-## Feature freeze on the 7th for the release on the 22nd
-
-The feature freeze on the 7th has been discontinued. The [transition period overview](https://gitlab.com/gitlab-org/release/docs/blob/21cbd409dd5f157fe252f254f3e897f01908abe2/general/deploy/auto-deploy-transition.md#transition)
-describes the change to this process. During the transition period, the only guarantee that
-a change will be included in the release on the 22nd is if the change has been
-deployed to GitLab.com prior to this date.
+## Feature flags
 
-### Feature flags
+Overview and details of feature flag processes in development of GitLab itself is described in [feature flags process documentation](https://docs.gitlab.com/ee/development/feature_flags/process.html).
 
-Merge requests that make changes hidden behind a feature flag, or remove an
-existing feature flag because a feature is deemed stable, may be merged (and
-picked into the stable branches) up to the 19th of the month. Such merge
-requests should have the ~"feature flag" label assigned, and don't require a
-corresponding exception request to be created.
+Guides on how to include feature flags in your backend/frontend code while developing GitLab are described in [developing with feature flags documentation](https://docs.gitlab.com/ee/development/feature_flags/developing.html).
 
-A level of common sense should be applied when deciding whether to have a feature
-behind a feature flag off or on by default.
+Getting access and how to expose the feature to users is detailed in [controlling feature flags documentation](https://docs.gitlab.com/ee/development/feature_flags/controls.html).
 
-The following guidelines can be applied to help make this decision:
+## Feature proposals from the 22nd to the 1st
 
-* If the feature is not fully ready or functioning, the feature flag should be disabled by default.
-* If the feature is ready but there are concerns about performance or impact, the feature flag should be enabled by default, but
-disabled via chatops before deployment on GitLab.com environments. If the performance concern is confirmed, the final release should have the feature flag disabled by default.
-* In most other cases, the feature flag can be enabled by default.
+To allow the Product and Engineering teams time to discuss issues that will be placed into an upcoming milestone,
+Product Managers must have their proposal for that milestone ready by the 22nd of each month.
 
-For more information on rolling out changes using feature flags, read [through the documentation](https://docs.gitlab.com/ee/development/rolling_out_changes_using_feature_flags.html).
+This proposal will be shared with Engineering for discussion, feedback, and planning.
+The plan for the upcoming milestone must be finalized by the 1st of the month, one week before kickoff on the 8th.
 
-In order to build the final package and present the feature for self-hosted
-customers, the feature flag should be removed. This should happen before the
-22nd, ideally _at least_ 2 days before. That means MRs with feature
-flags being picked at the 19th would have quite a tight schedule, so picking
-these _earlier_ is preferable.
+## Feature freeze on the 7th for the release on the 22nd
 
-While rare, release managers may decide to reject picking a change into a stable
-branch, even when feature flags are used. This might be necessary if the changes
-are deemed problematic, too invasive, or there simply isn't enough time to
-properly test how the changes behave on GitLab.com.
+The feature freeze on the 7th has been discontinued. [Transition period overview](https://gitlab.com/gitlab-org/release/docs/blob/21cbd409dd5f157fe252f254f3e897f01908abe2/general/deploy/auto-deploy-transition.md#transition)

 1. Configure PostgreSQL to listen on network interfaces:
 
-    For security reasons, PostgreSQL does not listen on any network interfaces
-    by default. However, Geo requires the **secondary** node to be able to
-    connect to the **primary** node's database. For this reason, we need the address of
-    each node. Note: For external PostgreSQL instances, see [additional instructions](external_database.md).
-
-    If you are using a cloud provider, you can lookup the addresses for each
-    Geo node through your cloud provider's management console.
-
-    To lookup the address of a Geo node, SSH in to the Geo node and execute:
-
-    ```sh
-    ##
-    ## Private address
-    ##
-    ip route get 255.255.255.255 | awk '{print "Private address:", $NF; exit}'
-
-    ##
-    ## Public address
-    ##
-    echo "External address: $(curl --silent ipinfo.io/ip)"
-    ```
-
-    In most cases, the following addresses will be used to configure GitLab
-    Geo:

-
-    If you are using Google Cloud Platform, SoftLayer, or any other vendor that
-    provides a virtual private cloud (VPC) you can use the **secondary** node's private
-    address (corresponds to "internal address" for Google Cloud Platform) for
-    `postgresql['md5_auth_cidr_addresses']` and `postgresql['listen_address']`.
-

-    with the interface corresponding to the given address. See [the PostgreSQL

+
+If you have many pipelines that access the same registry, it'll

+changes and credential rotations much simpler.

+access to the runner.
+

+
+1. Modify the Runner's `config.toml` file as follows:

+    ```
+
+1. Restart the Runner service.
+
+NOTE: **Note:** The double quotes included in the `DOCKER_AUTH_CONFIG`
+data must be escaped with backslashes. This prevents them from being
+interpreted as TOML.
+
+NOTE: **Note:** The `environment` option is a list. So your Runner may
+have existing entries and you should add this to the list, not replace
+it.

 each item takes the completed state of the previous (pending) merge ref, adds its own changes,
 and starts the pipeline immediately in parallel under the assumption that everything is going to pass.

 In this way, if all the pipelines in the train merge successfully, no pipeline time is wasted either queuing or retrying.
 If the button is subsequently pressed in a different MR, instead of creating a new pipeline for the target branch,
 it creates a new pipeline targeting the merge result of the previous MR plus the target branch.
 Pipelines invalidated through failures are immediately canceled and requeued.

-# Manage feature flags
-
-Starting from GitLab 9.3 we support feature flags for features in GitLab via
-[Flipper](https://github.com/jnunemaker/flipper/). You should use the `Feature`
-class (defined in `lib/feature.rb`) in your code to get, set and list feature
-flags.
-
-During runtime you can set the values for the gates via the
-[features API](../api/features.md) (accessible to admins only).
-
-## Feature groups
-
-Starting from GitLab 9.4 we support feature groups via
-[Flipper groups](https://github.com/jnunemaker/flipper/blob/v0.10.2/docs/Gates.md#2-group).
-
-Feature groups must be defined statically in `lib/feature.rb` (in the
-`.register_feature_groups` method), but their implementation can obviously be
-dynamic (querying the DB etc.).
-
-Once defined in `lib/feature.rb`, you will be able to activate a
-feature for a given feature group via the [`feature_group` param of the features API](../api/features.md#set-or-create-a-feature)
-
-For GitLab.com, [team members have access to feature flags through Chatops](chatops_on_gitlabcom.md). Only
-percentage gates are supported at this time. Setting a feature to be used 50% of
-the time, you should execute `/chatops run feature set my_feature_flag 50`.
-
-## Feature flags for user applications
-
-This document only covers feature flags used in the development of GitLab 
-itself. Feature flags in deployed user applications can be found at 
-[Feature Flags](../user/project/operations/feature_flags.md)
-
-## Developing with feature flags
-
-In general, it's better to have a group- or user-based gate, and you should prefer
-it over the use of percentage gates. This would make debugging easier, as you
-filter for example logs and errors based on actors too. Furthermore, this allows
-for enabling for the `gitlab-org` group first, while the rest of the users
-aren't impacted.
-
-```ruby
-# Good
-Feature.enabled?(:feature_flag, project)
-
-# Avoid, if possible
-Feature.enabled?(:feature_flag)
-```
-
-To use feature gates based on actors, the model needs to respond to
-`flipper_id`. For example, to enable for the Foo model:
-
-```ruby
-class Foo < ActiveRecord::Base
-  include FeatureGate
-end
-```
-
-Features that are developed and are intended to be merged behind a feature flag
-should not include a changelog entry. The entry should be added in the merge
-request removing the feature flags.
-
-In the rare case that you need the feature flag to be on automatically, use
-`default_enabled: true` when checking:
-
-```ruby
-Feature.enabled?(:feature_flag, project, default_enabled: true)
-```
-
-For more information about rolling out changes using feature flags, refer to the
-[Rolling out changes using feature flags](rolling_out_changes_using_feature_flags.md)
-guide.
-
-### Frontend
-
-For frontend code you can use the method `push_frontend_feature_flag`, which is
-available to all controllers that inherit from `ApplicationController`. Using
-this method you can expose the state of a feature flag as follows:
-
-```ruby
-before_action do
-  push_frontend_feature_flag(:vim_bindings)
-end
-
-def index
-  # ...
-end
-
-def edit
-  # ...
-end
-```
-
-You can then check for the state of the feature flag in JavaScript as follows:
-
-```javascript
-if ( gon.features.vimBindings ) {
-  // ...
-}
-```
-
-The name of the feature flag in JavaScript will always be camelCased, meaning
-that checking for `gon.features.vim_bindings` would not work.
-
-### Specs
-
-In the test environment `Feature.enabled?` is stubbed to always respond to `true`,
-so we make sure behavior under feature flag doesn't go untested in some non-specific
-contexts.
-
-Whenever a feature flag is present, make sure to test _both_ states of the
-feature flag.
-
-See the
-[testing guide](testing_guide/best_practices.md#feature-flags-in-tests)
-for information and examples on how to stub feature flags in tests.
-
-## Enabling a feature flag (in development)
-
-In the rails console (`rails c`), enter the following command to enable your feature flag
-
-```ruby
-Feature.enable(:feature_flag_name)
-```

+# Access for enabling a feature flag in production
+
+In order to be able to turn on/off features behind feature flags in any of the
+GitLab Inc. provided environments such as staging and production, you need to
+have access to the chatops bot. Chatops bot is currently running on the ops instance,
+which is different from GitLab.com or dev.gitlab.org.
+
+Follow the Chatops document to [request access](https://docs.gitlab.com/ee/development/chatops_on_gitlabcom.html#requesting-access).
+
+Once you are added to the project test if your access propagated,
+run:
+
+```
+/chatops run feature --help
+```
+
+## Rolling out changes
+
+When the changes are deployed to the environments it is time to start
+rolling out the feature to our users. The exact procedure of rolling out a
+change is unspecified, as this can vary from change to change. However, in
+general we recommend rolling out changes incrementally, instead of enabling them
+for everybody right away. We also recommend you to _not_ enable a feature
+_before_ the code is being deployed.
+This allows you to separate rolling out a feature from a deploy, making it
+easier to measure the impact of both separately.
+
+GitLab's feature library (using
+[Flipper](https://github.com/jnunemaker/flipper), and covered in the [Feature
+Flags process](process.md) guide) supports rolling out changes to a percentage of
+users. This in turn can be controlled using [GitLab chatops](../../ci/chatops/README.md).
+
+For an up to date list of feature flag commands please see [the source
+code](https://gitlab.com/gitlab-com/chatops/blob/master/lib/chatops/commands/feature.rb).
+Note that all the examples in that file must be preceded by
+`/chatops run`.
+
+If you get an error "Whoops! This action is not allowed. This incident
+will be reported." that means your Slack account is not allowed to
+change feature flags or you do not [have access](#access-for-enabling-a-feature-flag-in-production).
+
+### Enabling feature for staging and dev.gitlab.org
+
+As a first step in a feature rollout, you should enable the feature on <https://staging.gitlab.com>
+and <https://dev.gitlab.org>.
+
+For example, to enable a feature for 25% of all users, run the following in
+Slack:
+
+```
+/chatops run feature set new_navigation_bar 25 --dev
+/chatops run feature set new_navigation_bar 25 --staging
+```
+
+These two environments have different scopes.
+`dev.gitlab.org` is a production CE environment that has internal GitLab Inc.
+traffic and is used for some development and other related work.
+`staging.gitlab.com` has a smaller subset of GitLab.com database and repositories
+and does not have regular traffic. Staging is an EE instance and can give you
+a (very) rough estimate of how your feature will look/behave on GitLab.com.
+Both of these instances are connected to Sentry so make sure you check the projects
+there for any exceptions while testing your feature after enabling the feature flag.
+
+Once you are confident enough that these environments are in a good state with your
+feature enabled, you can roll out the change to GitLab.com.
+
+## Enabling feature for GitLab.com
+
+Similar to above, to enable a feature for 25% of all users, run the following in
+Slack:
+
+```
+/chatops run feature set new_navigation_bar 25
+```
+
+This will enable the feature for GitLab.com, with `new_navigation_bar` being the
+name of the feature.
+
+If you are not certain what percentages to use, simply use the following steps:
+
+1. 25%
+1. 50%
+1. 75%
+1. 100%
+
+Between every step you'll want to wait a little while and monitor the
+appropriate graphs on <https://dashboards.gitlab.net>. The exact time to wait
+may differ. For some features a few minutes is enough, while for others you may
+want to wait several hours or even days. This is entirely up to you, just make
+sure it is clearly communicated to your team, and the Production team if you
+anticipate any potential problems.
+
+Feature gates can also be actor based, for example a feature could first be
+enabled for only the `gitlab-ce` project. The project is passed by supplying a
+`--project` flag:
+
+```
+/chatops run feature set --project=gitlab-org/gitlab-ce some_feature true
+```
+
+For groups the `--group` flag is available:
+
+```
+/chatops run feature set --group=gitlab-org some_feature true
+```
+
+## Cleaning up
+
+Once the change is deemed stable, submit a new merge request to remove the
+feature flag. This ensures the change is available to all users and self-hosted
+instances. Make sure to add the ~"feature flag" label to this merge request so
+release managers are aware the changes are hidden behind a feature flag. If the
+merge request has to be picked into a stable branch, make sure to also add the
+appropriate "Pick into X" label (e.g. "Pick into XX.X").
+See [the process document](https://docs.gitlab.com/ee/development/feature_flags/process.html#including-a-feature-behind-feature-flag-in-the-final-release) for further details.
+
+When a feature gate has been removed from the code base, the value still exists
+in the database.
+This can be removed through ChatOps:
+
+```
+/chatops run feature delete some_feature
+```

+Feature.enabled?(:feature_flag)
+```
+
+To use feature gates based on actors, the model needs to respond to
+`flipper_id`. For example, to enable for the Foo model:
+
+```ruby

+  include FeatureGate
+end

+
+Features that are developed and are intended to be merged behind a feature flag
+should not include a changelog entry. The entry should be added in the merge

+In the rare case that you need the feature flag to be on automatically, use
+`default_enabled: true` when checking:
+
+```ruby
+Feature.enabled?(:feature_flag, project, default_enabled: true)
+```
+
+The [`Project#feature_available?`][project-fa],
+[`Namespace#feature_available?`][namespace-fa] (EE), and
+[`License.feature_available?`][license-fa] (EE) methods all implicitly check for
+a feature flag by the same name as the provided argument.
+
+For example if a feature is license-gated, there's no need to add an additional
+explicit feature flag check since the flag will be checked as part of the
+`License.feature_available?` call. Similarly, there's no need to "clean up" a
+feature flag once the feature has reached general availability.
+
+You'd still want to use an explicit `Feature.enabled?` check if your new feature
+isn't gated by a License or Plan.
+

+
+An important side-effect of the implicit feature flags mentioned above is that
+unless the feature is explicitly disabled or limited to a percentage of users,
+the feature flag check will default to `true`.
+
+As an example, if you were to ship the backend half of a feature behind a flag,
+you'd want to explicitly disable that flag until the frontend half is also ready
+to be shipped. [You can do this via Chatops](https://docs.gitlab.com/ee/development/feature_flags/controls.html):
+
+```
+/chatops run feature set some_feature 0
+```
+
+Note that you can do this at any time, even before the merge request using the
+flag has been merged!
+
+## Feature groups
+
+Starting from GitLab 9.4 we support feature groups via
+[Flipper groups](https://github.com/jnunemaker/flipper/blob/v0.10.2/docs/Gates.md#2-group).

+```
+
+You can then check for the state of the feature flag in JavaScript as follows:

+# Feature flags in development of GitLab
+
+Feature flags can be used to gradually roll out changes, be
+it a new feature, or a performance improvement. By using feature flags, we can
+comfortably measure the impact of our changes, while still being able to easily
+disable those changes, without having to revert an entire release.
+
+Before using feature flags for GitLab's development, read through the following:
+
+- [Process for using features flags](process.md).
+- [Developing with feature flags documentation](development.md).

+# Feature flags process
+
+## Feature flags for user applications
+
+This document only covers feature flags used in the development of GitLab
+itself. Feature flags in deployed user applications can be found at
+[Feature Flags feature documentation](../../user/project/operations/feature_flags.md).
+
+## Feature flags in GitLab development
+
+The following highlights should be considered when deciding if feature flags
+should be leveraged:
+
+- By default, the feature flags should be **off**.
+- Feature flags should remain in the codebase for as short period as possible
+  to reduce the need for feature flag accounting.
+- The person operating with feature flags is responsible for clearly communicating
+  the status of a feature behind the feature flag with responsible stakeholders.
+- Merge requests that make changes hidden behind a feature flag, or remove an
+  existing feature flag because a feature is deemed stable must have the
+  ~"feature flag" label assigned.
+
+One might be tempted to think that feature flags will delay the release of a
+feature by at least one month (= one release). This is not the case. A feature
+flag does not have to stick around for a specific amount of time
+(e.g. at least one release), instead they should stick around until the feature
+is deemed stable. Stable means it works on GitLab.com without causing any
+problems, such as outages.
+
+### When to use feature flags
+
+Starting with GitLab 11.4, developers are required to use feature flags for
+non-trivial changes. Such changes include:
+
+- New features (e.g. a new merge request widget, epics, etc).
+- Complex performance improvements that may require additional testing in
+  production, such as rewriting complex queries.
+- Invasive changes to the user interface, such as a new navigation bar or the
+  removal of a sidebar.
+- Adding support for importing projects from a third-party service.
+
+In all cases, those working on the changes can best decide if a feature flag is
+necessary. For example, changing the color of a button doesn't need a feature
+flag, while changing the navigation bar definitely needs one. In case you are
+uncertain if a feature flag is necessary, simply ask about this in the merge
+request, and those reviewing the changes will likely provide you with an answer.
+
+When using a feature flag for UI elements, make sure to _also_ use a feature
+flag for the underlying backend code, if there is any. This ensures there is
+absolutely no way to use the feature until it is enabled.
+
+### Including a feature behind feature flag in the final release
+
+In order to build a final release and present the feature for self-hosted
+users, the feature flag should be at least defaulted to **on**. If the feature
+is deemed stable and there is confidence that removing the feature flag is safe,
+consider removing the feature flag altogether. Take into consideration that such
+action can make the feature available on GitLab.com shortly after the change to
+the feature flag is merged.
+
+Changing the default state or removing the feature flag has to be done before
+the 22nd of the month, _at least_ 2 working days before, in order for the change
+to be included in the final self-managed release.
+
+In addition to this, the feature behind feature flag should:
+
+- Run in all GitLab.com environments for a sufficient period of time. This time
+  period depends on the feature behind the feature flag, but as a general rule of
+  thumb 2-4 working days should be sufficient to gather enough feedback.
+- The feature should be exposed to all users within the GitLab.com plan during
+  the above mentioned period of time. Exposing the feature to a smaller percentage
+  or only a group of users might not expose a sufficient amount of information to aid in
+  making a decision on feature stability.
+
+While rare, release managers may decide to reject picking or revert a change in
+a stable branch, even when feature flags are used. This might be necessary if
+the changes are deemed problematic, too invasive, or there simply isn't enough
+time to properly measure how the changes behave on GitLab.com.
+
+### The cost of feature flags
+
+When reading the above, one might be tempted to think this procedure is going to
+add a lot of work. Fortunately, this is not the case, and we'll show why. For
+this example we'll specify the cost of the work to do as a number, ranging from
+0 to infinity. The greater the number, the more expensive the work is. The cost
+does _not_ translate to time, it's just a way of measuring complexity of one
+change relative to another.
+
+Let's say we are building a new feature, and we have determined that the cost of
+this is 10. We have also determined that the cost of adding a feature flag check
+in a variety of places is 1. If we do not use feature flags, and our feature
+works as intended, our total cost is 10. This however is the best case scenario.
+Optimizing for the best case scenario is guaranteed to lead to trouble, whereas
+optimizing for the worst case scenario is almost always better.
+
+To illustrate this, let's say our feature causes an outage, and there's no
+immediate way to resolve it. This means we'd have to take the following steps to
+resolve the outage:
+
+1. Revert the release.
+1. Perform any cleanups that might be necessary, depending on the changes that
+   were made.
+1. Revert the commit, ensuring the "master" branch remains stable. This is
+   especially necessary if solving the problem can take days or even weeks.
+1. Pick the revert commit into the appropriate stable branches, ensuring we
+   don't block any future releases until the problem is resolved.
+
+As history has shown, these steps are time consuming, complex, often involve
+many developers, and worst of all: our users will have a bad experience using
+GitLab.com until the problem is resolved.
+
+Now let's say that all of this has an associated cost of 10. This means that in
+the worst case scenario, which we should optimize for, our total cost is now 20.
+
+If we had used a feature flag, things would have been very different. We don't
+need to revert a release, and because feature flags are disabled by default we
+don't need to revert and pick any Git commits. In fact, all we have to do is
+disable the feature, and in the worst case, perform cleanup. Let's say that
+the cost of this is 2. In this case, our best case cost is 11: 10 to build the
+feature, and 1 to add the feature flag. The worst case cost is now 13: 10 to
+build the feature, 1 to add the feature flag, and 2 to disable and clean up.
+
+Here we can see that in the best case scenario the work necessary is only a tiny
+bit more compared to not using a feature flag. Meanwhile, the process of
+reverting our changes has been made significantly and reliably cheaper.
+
+In other words, feature flags do not slow down the development process. Instead,
+they speed up the process as managing incidents now becomes _much_ easier. Once
+continuous deployments are easier to perform, the time to iterate on a feature
+is reduced even further, as you no longer need to wait weeks before your changes
+are available on GitLab.com.

-# Rolling out changes using feature flags
-
-[Feature flags](feature_flags.md) can be used to gradually roll out changes, be
-it a new feature, or a performance improvement. By using feature flags, we can
-comfortably measure the impact of our changes, while still being able to easily
-disable those changes, without having to revert an entire release.
-
-## When to use feature flags
-
-Starting with GitLab 11.4, developers are required to use feature flags for
-non-trivial changes. Such changes include:
-
-- New features (e.g. a new merge request widget, epics, etc).
-- Complex performance improvements that may require additional testing in
-  production, such as rewriting complex queries.
-- Invasive changes to the user interface, such as a new navigation bar or the
-  removal of a sidebar.
-- Adding support for importing projects from a third-party service.
-
-In all cases, those working on the changes can best decide if a feature flag is
-necessary. For example, changing the color of a button doesn't need a feature
-flag, while changing the navigation bar definitely needs one. In case you are
-uncertain if a feature flag is necessary, simply ask about this in the merge
-request, and those reviewing the changes will likely provide you with an answer.
-
-When using a feature flag for UI elements, make sure to _also_ use a feature
-flag for the underlying backend code, if there is any. This ensures there is
-absolutely no way to use the feature until it is enabled.
-
-## The cost of feature flags
-
-When reading the above, one might be tempted to think this procedure is going to
-add a lot of work. Fortunately, this is not the case, and we'll show why. For
-this example we'll specify the cost of the work to do as a number, ranging from
-0 to infinity. The greater the number, the more expensive the work is. The cost
-does _not_ translate to time, it's just a way of measuring complexity of one
-change relative to another.
-
-Let's say we are building a new feature, and we have determined that the cost of
-this is 10. We have also determined that the cost of adding a feature flag check
-in a variety of places is 1. If we do not use feature flags, and our feature
-works as intended, our total cost is 10. This however is the best case scenario.
-Optimising for the best case scenario is guaranteed to lead to trouble, whereas
-optimising for the worst case scenario is almost always better.
-
-To illustrate this, let's say our feature causes an outage, and there's no
-immediate way to resolve it. This means we'd have to take the following steps to
-resolve the outage:
-
-1. Revert the release.
-1. Perform any cleanups that might be necessary, depending on the changes that
-   were made.
-1. Revert the commit, ensuring the "master" branch remains stable. This is
-   especially necessary if solving the problem can take days or even weeks.
-1. Pick the revert commit into the appropriate stable branches, ensuring we
-   don't block any future releases until the problem is resolved.
-
-As history has shown, these steps are time consuming, complex, often involve
-many developers, and worst of all: our users will have a bad experience using
-GitLab.com until the problem is resolved.
-
-Now let's say that all of this has an associated cost of 10. This means that in
-the worst case scenario, which we should optimise for, our total cost is now 20.
-
-If we had used a feature flag, things would have been very different. We don't
-need to revert a release, and because feature flags are disabled by default we
-don't need to revert and pick any Git commits. In fact, all we have to do is
-disable the feature, and in the worst case, perform cleanup. Let's say that 
-the cost of this is 2. In this case, our best case cost is 11: 10 to build the 
-feature, and 1 to add the feature flag. The worst case cost is now 13: 10 to 
-build the feature, 1 to add the feature flag, and 2 to disable and clean up.
-
-Here we can see that in the best case scenario the work necessary is only a tiny
-bit more compared to not using a feature flag. Meanwhile, the process of
-reverting our changes has been made significantly and reliably cheaper.
-
-In other words, feature flags do not slow down the development process. Instead,
-they speed up the process as managing incidents now becomes _much_ easier. Once
-continuous deployments are easier to perform, the time to iterate on a feature
-is reduced even further, as you no longer need to wait weeks before your changes
-are available on GitLab.com.
-
-## Rolling out changes
-
-The procedure of using feature flags is straightforward, and similar to not
-using them. You add the necessary tests (make sure to test both the on and off
-states of your feature flag(s)), make sure they all pass, have the code
-reviewed, etc. You then submit your merge request, and add the ~"feature flag"
-label. This label is used to signal to release managers that your changes are
-hidden behind a feature flag and that it is safe to pick the MR into a stable
-branch, without the need for an exception request.
-
-When the changes are deployed it is time to start rolling out the feature to our
-users. The exact procedure of rolling out a change is unspecified, as this can
-vary from change to change. However, in general we recommend rolling out changes
-incrementally, instead of enabling them for everybody right away. We also
-recommend you to _not_ enable a feature _before_ the code is being deployed.
-This allows you to separate rolling out a feature from a deploy, making it
-easier to measure the impact of both separately.
-
-GitLab's feature library (using
-[Flipper](https://github.com/jnunemaker/flipper), and covered in the [Feature
-Flags](feature_flags.md) guide) supports rolling out changes to a percentage of
-users. This in turn can be controlled using [GitLab
-chatops](../ci/chatops/README.md).
-
-For an up to date list of feature flag commands please see [the source
-code](https://gitlab.com/gitlab-com/chatops/blob/master/lib/chatops/commands/feature.rb).
-Note that all the examples in that file must be preceded by
-`/chatops run`.
-
-If you get an error "Whoops! This action is not allowed. This incident
-will be reported." that means your Slack account is not allowed to
-change feature flags. To test if you are allowed to do anything at all,
-run:
-
-```
-/chatops run feature --help
-```
-
-For example, to enable a feature for 25% of all users, run the following in
-Slack:
-
-```
-/chatops run feature set new_navigation_bar 25
-```
-
-This will enable the feature for GitLab.com, with `new_navigation_bar` being the
-name of the feature. We can also enable the feature for <https://dev.gitlab.org>
-or <https://staging.gitlab.com>:
-
-```
-/chatops run feature set new_navigation_bar 25 --dev
-/chatops run feature set new_navigation_bar 25 --staging
-```
-
-If you are not certain what percentages to use, simply use the following steps:
-
-1. 25%
-1. 50%
-1. 75%
-1. 100%
-
-Between every step you'll want to wait a little while and monitor the
-appropriate graphs on <https://dashboards.gitlab.net>. The exact time to wait
-may differ. For some features a few minutes is enough, while for others you may
-want to wait several hours or even days. This is entirely up to you, just make
-sure it is clearly communicated to your team, and the Production team if you
-anticipate any potential problems.
-
-Feature gates can also be actor based, for example a feature could first be
-enabled for only the `gitlab-ce` project. The project is passed by supplying a
-`--project` flag:
-
-```
-/chatops run feature set --project=gitlab-org/gitlab-ce some_feature true
-```
-
-For groups the `--group` flag is available:
-
-```
-/chatops run feature set --group=gitlab-org some_feature true
-```
-
-Once a change is deemed stable, submit a new merge request to remove the
-feature flag. This ensures the change is available to all users and self-hosted
-instances. Make sure to add the ~"feature flag" label to this merge request so
-release managers are aware the changes are hidden behind a feature flag. If the
-merge request has to be picked into a stable branch (e.g. after the 7th), make
-sure to also add the appropriate "Pick into X" label (e.g. "Pick into 11.4").
-
-One might be tempted to think this will delay the release of a feature by at
-least one month (= one release). This is not the case. A feature flag does not
-have to stick around for a specific amount of time (e.g. at least one release),
-instead they should stick around until the feature is deemed stable. Stable
-means it works on GitLab.com without causing any problems, such as outages. In
-most cases this will translate to a feature (with a feature flag) being shipped
-in RC1, followed by the feature flag being removed in RC2. This in turn means
-the feature will be stable by the time we publish a stable package around the
-22nd of the month.
-
-## Implicit feature flags
-
-The [`Project#feature_available?`][project-fa],
-[`Namespace#feature_available?`][namespace-fa] (EE), and
-[`License.feature_available?`][license-fa] (EE) methods all implicitly check for
-a feature flag by the same name as the provided argument.
-
-For example if a feature is license-gated, there's no need to add an additional
-explicit feature flag check since the flag will be checked as part of the
-`License.feature_available?` call. Similarly, there's no need to "clean up" a
-feature flag once the feature has reached general availability.
-
-You'd still want to use an explicit `Feature.enabled?` check if your new feature
-isn't gated by a License or Plan.

-
-### Undefined feature flags default to "on"
-
-An important side-effect of the [implicit feature flags](#implicit-feature-flags) 
-mentioned above is that unless the feature is explicitly disabled or limited to a 
-percentage of users, the feature flag check will default to `true`.
-
-As an example, if you were to ship the backend half of a feature behind a flag,
-you'd want to explicitly disable that flag until the frontend half is also ready
-to be shipped. You can do this via ChatOps:
-
-```
-/chatops run feature set some_feature 0
-```
-
-Note that you can do this at any time, even before the merge request using the
-flag has been merged!
-
-### Cleaning up
-
-When a feature gate has been removed from the code base, the value still exists
-in the database. This can be removed through ChatOps:
-
-```
-/chatops run feature delete some_feature
-```

+## Remove orphan artifact files
+
+When you notice there are more job artifacts files on disk than there
+should be, you can run:
+
+```shell
+gitlab-rake gitlab:cleanup:orphan_job_artifact_files
+```
+
+This command:
+
+- Scans through the entire artifacts folder.
+- Checks which files still have a record in the database.
+- If no database record is found, the file is deleted from disk.
+
+By default, this task does not delete anything but shows what it can
+delete. Run the command with `DRY_RUN=false` if you actually want to
+delete the files:
+
+```shell
+gitlab-rake gitlab:cleanup:orphan_job_artifact_files DRY_RUN=false
+```
+
+You can also limit the number of files to delete with `LIMIT`:
+
+```shell
+gitlab-rake gitlab:cleanup:orphan_job_artifact_files LIMIT=100`
+```
+
+This will only delete up to 100 files from disk. You can use this to
+delete a small set for testing purposes.
+
+If you provide `DEBUG=1`, you'll see the full path of every file that
+is detected as being an orphan.
+
+If `ionice` is installed, the tasks uses it to ensure the command is
+not causing too much load on the disk. You can configure the niceness
+level with `NICENESS`. Below are the valid levels, but consult
+`man 1 ionice` to be sure.

 ### Customizing `.gitlab-ci.yml`
 
-If you want to modify the CI/CD pipeline used by Auto DevOps, you can copy the
-[Auto DevOps template] into your project's repo and edit as you see fit.
-
-Assuming that your project is new or it doesn't have a `.gitlab-ci.yml` file
-present:
-
-1. From your project home page, either click on the "Set up CI/CD" button, or click
-   on the plus button and (`+`), then "New file"
-1. Pick `.gitlab-ci.yml` as the template type
-1. Select "Auto-DevOps" from the template dropdown
-1. Edit the template or add any jobs needed
-1. Give an appropriate commit message and hit "Commit changes"
-
-TIP: **Tip:** The Auto DevOps template includes useful comments to help you
-customize it. For example, if you want deployments to go to a staging environment
-instead of directly to a production one, you can enable the `staging` job by
-renaming `.staging` to `staging`. Then make sure to uncomment the `when` key of
-the `production` job to turn it into a manual action instead of deploying
-automatically.

+is just an example of a [`.gitlab-ci.yml`](../../ci/yaml/README.md) and uses

+Auto DevOps is completely customizable because the [Auto DevOps template]:
+
+- Is just an implementation of a [`.gitlab-ci.yml`](../../ci/yaml/README.md) file.
+- Uses only features available to any implementation of `.gitlab-ci.yml`.
+
+If you want to modify the CI/CD pipeline used by Auto DevOps, you can [`include`
+the template](../../ci/yaml/README.md#includetemplate) and customize as
+needed. To do this, add a `.gitlab-ci.yml` file to the root of your repository
+containing the following:
+
+```yml
+include:
+  - template: Auto-DevOps.gitlab-ci.yml
+```
+
+Then add any extra changes you want. Your additions will be merged with the
+[Auto DevOps template] using the behaviour described for
+[`include`](../../ci/yaml/README.md#include).
+
+It is also possible to copy and paste the contents of the [Auto DevOps
+template] into your project and edit this as needed. You may prefer to do it
+that way if you want to specifically remove any part of it.

+## Monitoring section
+
+The following topics document the **Monitoring** section of the Admin Area.
+
+### System Info
+
+The **System Info** page provides the following statistics:
+
+| Field        | Description |
+| :----------- | :---------- |
+| CPU          | Number of CPU cores available |
+| Memory Usage | Memory in use, and total memory available |
+| Disk Usage   | Disk space in use, and total disk space available |
+| Uptime       | Approximate uptime of the GitLab instance |
+
+These statistics are updated only when you navigate to the **System Info** page, or you refresh the page in your browser.
+
+### Background Jobs
+
+The **Background Jobs** page displays the Sidekiq dashboard. Sidekiq is used by GitLab to
+perform processing in the background.
+
+The Sidekiq dashboard consists of the following elements:
+
+- A tab per jobs' status.
+- A breakdown of background job statistics.
+- A live graph of **Processed** and **Failed** jobs, with a selectable polling interval.
+- An historical graph of **Processed** and **Failed** jobs, with a selectable time span.
+- Redis statistics, including:
+  - Version number
+  - Uptime, measured in days
+  - Number of connections
+  - Current memory usage, measured in MB
+  - Peak memory usage, measured in MB
+
+### Logs
+
+The **Logs** page provides access to the following log files:
+
+| Log file                | Contents |
+| :---------------------- | :------- |
+| `application.log`       | GitLab user activity |
+| `githost.log`           | Failed GitLab interaction with Git repositories |
+| `production.log`        | Requests received from Unicorn, and the actions taken to serve those requests |
+| `sidekiq.log`           | Background jobs |
+| `repocheck.log`         | Repository activity |
+| `integrations_json.log` | Activity between GitLab and integrated systems |
+| `kubernetes.log`        | Kubernetes activity |
+
+The contents of these log files can be useful when troubleshooting a problem. Access is available to GitLab admins, without requiring direct access to the log files.
+
+For details of these log files and their contents, see [Log system](../../administration/logs.md).
+
+The content of each log file is listed in chronological order. To minimize performance issues, a maximum 2000 lines of each log file are shown.
+
+### Requests Profiles
+
+The **Requests Profiles** page contains the token required for profiling. For more details, see [Request Profiling](../../administration/monitoring/performance/request_profiling.md).
+
+### Audit Log **[PREMIUM ONLY]**
+
+The **Audit Log** page lists changes made within the GitLab server. With this information you can control, analyze, and track every change.

+| [Container Scanning](container_scanning/index.md)            | Uses `clair` underneath and the latest `clair-db` version is used for each job run by running the [`latest` docker image tag](https://gitlab.com/gitlab-org/gitlab-ee/blob/438a0a56dc0882f22bdd82e700554525f552d91b/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml#L37). The `clair-db` database [is updated daily according to the author](https://github.com/arminc/clair-local-scan#clair-server-or-local). |
+| [Dependency Scanning](dependency_scanning/index.md)          | Relies on `bundler-audit` (for Rubygems), `retire.js` (for NPM packages) and `gemnasium` (GitLab's own tool for all libraries). `bundler-audit` and `retire.js` both fetch their vulnerabilities data from GitHub repositories, so vulnerabilities added to `ruby-advisory-db` and `retire.js` are immediately available. The tools themselves are updated once per month if there's a new version. The [Gemnasium DB](https://gitlab.com/gitlab-org/security-products/gemnasium-db) is updated at least once a week. |
+| [Dynamic Application Security Testing (DAST)](dast/index.md) | Updated weekly on Sundays. The underlying tool, `zaproxy`, downloads fresh rules at startup. |
+| [Static Application Security Testing (SAST)](sast/index.md)  | Relies exclusively on [the tools GitLab is wrapping](sast/index.md#supported-languages-and-frameworks). The underlying analyzers are updated at least once per month if a relevant update is available. The vulnerabilities database is updated by the upstream tools. |
+
+You don't have to update GitLab to benefit from the latest vulnerabilities definitions,
+but you may have to in the future.
+
+The security tools are released as Docker images, and the vendored job definitions
+to enable them are using the `x-y-stable` image tags that get overridden each time a new
+release of the tools is pushed. The Docker images are updated to match the
+previous GitLab releases, so they automatically get the latest versions of the
+scanning tools without the user having to do anything.
+
+This workflow comes with some drawbacks and there's a
+[plan to change this](https://gitlab.com/gitlab-org/gitlab-ee/issues/9725).

 It is also possible to use GitLab Serverless with an existing Kubernetes
 cluster which already has Knative installed.
 
-Simply:
+You must do the following:
 
 1. Follow the steps to
    [add an existing Kubernetes cluster](../index.md#adding-an-existing-kubernetes-cluster).
+
+1. Ensure GitLab can manage Knative:
+    - For a non-GitLab managed cluster, ensure that the service account for the token
+      provided can manage resources in the `serving.knative.dev` API group.
+    - For a GitLab managed cluster,
+      GitLab uses a service account with the `edit` cluster role. This account needs
+      the ability to manage resources in the `serving.knative.dev` API group.
+      We suggest you do this with an [aggregated ClusterRole](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#aggregated-clusterroles)
+      adding rules to the default `edit` cluster role:
+      First, save the following YAML as `knative-serving-only-role.yaml`:

+
+## Enabling TLS for Knative services
+
+By default, a GitLab serverless deployment will be served over `http`. In order to serve over `https` you
+must manually obtain and install TLS certificates.
+
+The simplest way to accomplish this is to 
+use [Certbot to manually obtain Let's Encrypt certificates](https://knative.dev/docs/serving/using-a-tls-cert/#using-certbot-to-manually-obtain-let-s-encrypt-certificates). Certbot is a free, open source software tool for automatically using Let’s Encrypt certificates on manually-administrated websites to enable HTTPS.
+
+NOTE: **Note:**
+The instructions below relate to installing and running Certbot on a Linux server and may not work on other operating systems.
+
+1. Install Certbot by running the 
+   [`certbot-auto` wrapper script](https://certbot.eff.org/docs/install.html#certbot-auto).
+   On the command line of your server, run the following commands:
+
+    ```sh
+    wget https://dl.eff.org/certbot-auto
+    sudo mv certbot-auto /usr/local/bin/certbot-auto
+    sudo chown root /usr/local/bin/certbot-auto
+    chmod 0755 /usr/local/bin/certbot-auto
+    /usr/local/bin/certbot-auto --help
+    ```
+
+    To check the integrity of the `certbot-auto` script, run:
+
+      ```sh
+      wget -N https://dl.eff.org/certbot-auto.asc
+      gpg2 --keyserver ipv4.pool.sks-keyservers.net --recv-key A2CFB51FA275A7286234E7B24D17C995CD9775F2
+      gpg2 --trusted-key 4D17C995CD9775F2 --verify certbot-auto.asc /usr/local/bin/certbot-auto
+      ```
+
+    The output of the last command should look something like:
+
+      ```sh
+      gpg: Signature made Mon 10 Jun 2019 06:24:40 PM EDT
+      gpg:                using RSA key A2CFB51FA275A7286234E7B24D17C995CD9775F2
+      gpg: key 4D17C995CD9775F2 marked as ultimately trusted
+      gpg: checking the trustdb
+      gpg: marginals needed: 3  completes needed: 1  trust model: pgp
+      gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u
+      gpg: next trustdb check due at 2027-11-22
+      gpg: Good signature from "Let's Encrypt Client Team <letsencrypt-client@eff.org>" [ultimate]
+      ```
+
+1. Run the following command to use Certbot to request a certificate
+   using DNS challenge during authorization:
+
+
+    ```sh
+    ./certbot-auto certonly --manual --preferred-challenges dns -d '*.<namespace>.example.com'
+    ```
+
+    Where `<namespace>` is the namespace created by GitLab for your serverless project (composed of `<projectname+id>`) and
+    `example.com` is the domain being used for your project. If you are unsure what the namespace of your project is, navigate
+    to the **Operations > Serverless** page of your project and inspect
+    the endpoint provided for your function/app.
+
+    ![function_endpoint](img/function-endpoint.png)
+
+    In the above image, the namespace for the project is `node-function-11909507` and the domain is `knative.info`, thus
+    certificate request line would look like this:
+
+    ```sh
+    ./certbot-auto certonly --manual --preferred-challenges dns -d '*.node-function-11909507.knative.info'
+    ```
+
+    The Certbot tool walks you through the steps of validating that you own each domain that you specify by creating TXT records in those domains.
+    After this process is complete, the output should look something like this:
+
+    ```sh
+    IMPORTANT NOTES:
+    - Congratulations! Your certificate and chain have been saved at:
+      /etc/letsencrypt/live/namespace.example.com/fullchain.pem
+      Your key file has been saved at:
+      /etc/letsencrypt/live/namespace.example/privkey.pem
+      Your cert will expire on 2019-09-19. To obtain a new or tweaked
+      version of this certificate in the future, simply run certbot-auto
+      again. To non-interactively renew *all* of your certificates, run
+      "certbot-auto renew"
+    -----BEGIN PRIVATE KEY-----
+    - Your account credentials have been saved in your Certbot
+      configuration directory at /etc/letsencrypt. You should make a

+      making regular backups of this folder is ideal.
+    ```
+
+1. Create certificate and private key files. Using the contents of the files
+   returned by Certbot, we'll create two files in order to create the

+
+1. Create a Kubernetes secret to hold your TLS certificate, `cert.pem`, and
+   the private key `cert.pk`:
+
+    NOTE: **Note:**
+    Running `kubectl` commands on your cluster requires setting up access to the cluster first.
+    For clusters created on GKE, see
+    [GKE Cluster Access](https://cloud.google.com/kubernetes-engine/docs/how-to/cluster-access-for-kubectl).
+    For other platforms, [install `kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/).
+
+    ```sh
+    kubectl create --namespace istio-system secret tls istio-ingressgateway-certs \
+    --key cert.pk \
+    --cert cert.pem
+    ```
+
+    Where `cert.pem` and `cert.pk` are your certificate and private key files. Note that the `istio-ingressgateway-certs` secret name is required.
+
+1. Configure Knative to use the new secret that you created for HTTPS
+   connections. Run the 
+  following command to open the Knative shared `gateway` in edit mode:
+
+    ```sh
+    kubectl edit gateway knative-ingress-gateway --namespace knative-serving
+    ```
+
+      Update the gateway to include the following tls: section and configuration:
+
+      ```sh
+      tls:
+        mode: SIMPLE
+        privateKey: /etc/istio/ingressgateway-certs/tls.key
+        serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
+      ```
+
+      Example:
+
+      ```sh
+      apiVersion: networking.istio.io/v1alpha3
+      kind: Gateway
+      metadata:
+        # ... skipped ...
+      spec:
+        selector:
+          istio: ingressgateway
+        servers:
+          - hosts:
+              - "*"
+            port:
+              name: http
+              number: 80
+              protocol: HTTP
+          - hosts:
+              - "*"
+            port:
+              name: https
+              number: 443
+              protocol: HTTPS
+            tls:
+              mode: SIMPLE
+              privateKey: /etc/istio/ingressgateway-certs/tls.key
+              serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
+      ```
+
+      After your changes are running on your Knative cluster, you can begin using the HTTPS protocol for secure access your deployed Knative services.
+      In the event a mistake is made during this process and you need to update the cert, you will need to edit the gateway `knative-ingress-gateway`
+      to switch back to `PASSTHROUGH` mode. Once corrections are made, edit the file again so the gateway will use the new certificates.

+## Project aliases **[PREMIUM ONLY]**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/3264) in [GitLab Premium](https://about.gitlab.com/pricing/) 12.1.
+
+When migrating repositories to GitLab and they are being accessed by other systems,
+it's very useful to be able to access them using the same name especially when
+they are a lot. It reduces the risk of changing significant number of Git URLs in
+a large number of systems.
+
+GitLab provides a functionality to help with this. In GitLab, repositories are
+usually accessed with a namespace and project name. It is also possible to access
+them via a project alias. This feature is only available on Git over SSH.
+
+A project alias can be only created via API and only by GitLab administrators.
+Follow the [Project Aliases API documentation](../../api/project_aliases.md) for
+more details.
+
+Once an alias has been created for a project (e.g., an alias `gitlab-ce` for the
+project `https://gitlab.com/gitlab-org/gitlab-ce`), the repository can be cloned
+using the alias (e.g `git clone git@gitlab.com:gitlab-ce.git` instead of
+`git clone git@gitlab.com:gitlab-org/gitlab-ce.git`).
