-
-When gathering statistics (e.g. the output of `EXPLAIN ANALYZE`) you should make
-sure your database has enough data. Having around 10 000 rows in the tables
-being queries should provide a reasonable estimate of how a query will behave.
-Also make sure that PostgreSQL uses the following settings:
-
-* `random_page_cost`: `1`
-* `work_mem`: `16MB`
-* `maintenance_work_mem`: at least `64MB`
-* `shared_buffers`: at least `256MB`
-
-If you have access to GitLab.com's staging environment you should also run your
-measurements there, and include the results in this MR.
+Add a description of your merge request here. Merge requests without an adequate
+description will not be reviewed until one is added.

+### GitLab: API is not accessible
+
+This often occurs when gitlab-shell attempts to request authorization via the
+internal API (e.g., `http://localhost:8080/api/v4/internal/allowed`), and
+something in the check fails. There are many reasons why this may happen:
+
+1. Timeout connecting to a database (e.g., PostgreSQL or Redis)
+1. Error in Git hooks or push rules
+1. Error accessing the repository (e.g., stale NFS handles)
+
+To diagnose this problem, try to reproduce the problem and then see if there
+is a unicorn worker that is spinning via `top`. Try to use the `gdb`
+techniques above. In addition, using `strace` may help isolate issues:
+
+```shell
+strace -tt -T -f -s 1024 -p <PID of unicorn worker> -o /tmp/unicorn.txt
+```
+
+If you cannot isolate which Unicorn worker is the issue, try to run `strace`
+on all the Unicorn workers to see where the `/internal/allowed` endpoint gets
+stuck:
+
+```shell
+ps auwx | grep unicorn | awk '{ print " -p " $2}' | xargs strace -tt -T -f -s 1024 -o /tmp/unicorn.txt
+```
+
+The output in `/tmp/unicorn.txt` may help diagnose the root cause.

+# Autoscaling GitLab Runner on AWS
+
+One of the biggest advantages of GitLab Runner is its ability to automatically
+spin up and down VMs to make sure your builds get processed immediately. It's a
+great feature, and if used correctly, it can be extremely useful in situations
+where you don't use your Runners 24/7 and want to have a cost-effective and
+scalable solution.
+
+## Introduction
+
+In this tutorial, we'll explore how to properly configure a GitLab Runner in
+AWS that will serve as the bastion where it will spawn new Docker machines on
+demand.
+
+In addition, we'll make use of [Amazon's EC2 Spot instances][spot] which will
+greatly reduce the costs of the Runner instances while still using quite
+powerful autoscaling machines.
+
+## Prerequisites
+
+NOTE: **Note:**
+A familiarity with Amazon Web Services (AWS) is required as this is where most
+of the configuration will take place.
+
+Your GitLab instance is going to need to talk to the Runners over the network,
+and that is something you need think about when configuring any AWS security
+groups or when setting up your DNS configuration.
+
+For example, you can keep the EC2 resources segmented away from public traffic
+in a different VPC to better strengthen your network security. Your environment
+is likely different, so consider what works best for your situation.
+
+### AWS security groups
+
+Docker Machine will attempt to use a
+[default security group](https://docs.docker.com/machine/drivers/aws/#security-group)
+with rules for port `2376`, which is required for communication with the Docker
+daemon. Instead of relying on Docker, you can create a security group with the
+rules you need and provide that in the Runner options as we will
+[see below](#the-runners-machine-section). This way, you can customize it to your
+liking ahead of time based on your networking environment.
+
+### AWS credentials
+
+You'll need an [AWS Access Key](https://docs.aws.amazon.com/general/latest/gr/managing-aws-access-keys.html)
+tied to a user with permission to scale (EC2) and update the cache (via S3).
+Create a new user with [policies](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-policies-for-amazon-ec2.html)
+for EC2 (AmazonEC2FullAccess) and S3 (AmazonS3FullAccess). To be more secure,
+you can disable console login for that user. Keep the tab open or copy paste the
+security credentials in an editor as we'll use them later during the
+[Runner configuration](#the-runners-machine-section).
+
+## Prepare the bastion instance
+
+The first step is to install GitLab Runner in an EC2 instance that will serve
+as the bastion that spawns new machines. This doesn't have to be a powerful
+machine since it will not run any jobs itself, a `t2.micro` instance will do.
+This machine will be a dedicated host since we need it always up and running,
+thus it will be the only standard cost.
+
+NOTE: **Note:**
+For the bastion instance, choose a distribution that both Docker and GitLab
+Runner support, for example either Ubuntu, Debian, CentOS or RHEL will work fine.
+
+Install the prerequisites:
+
+1. Log in to your server
+1. [Install GitLab Runner from the official GitLab repository](https://docs.gitlab.com/runner/install/linux-repository.html)
+1. [Install Docker](https://docs.docker.com/engine/installation/#server)
+1. [Install Docker Machine](https://docs.docker.com/machine/install-machine/)
+
+Now that the Runner is installed, it's time to register it.
+
+## Registering the GitLab Runner
+
+Before configuring the GitLab Runner, you need to first register it, so that
+it connects with your GitLab instance:
+
+1. [Obtain a Runner token](../../ci/runners/README.md)
+1. [Register the Runner](https://docs.gitlab.com/runner/register/index.html#gnu-linux)
+1. When asked the executor type, enter `docker+machine`
+
+You can now move on to the most important part, configuring the GitLab Runner.
+
+TIP: **Tip:**
+If you want every user in your instance to be able to use the autoscaled Runners,
+register the Runner as a shared one.
+
+## Configuring the GitLab Runner
+
+Now that the Runner is registered, you need to edit its configuration file and
+add the required options for the AWS machine driver.
+
+Let's first break it down to pieces.
+
+### The global section
+
+In the global section, you can define the limit of the jobs that can be run
+concurrently across all Runners (`concurrent`). This heavily depends on your
+needs, like how many users your Runners will accommodate, how much time your
+builds take, etc. You can start with something low like `10`, and increase or
+decrease its value going forward.
+
+The `check_interval` option defines how often the Runner should check GitLab
+for new jobs, in seconds.
+
+Example:
+
+```toml
+concurrent = 10
+check_interval = 0
+```
+
+[Read more](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-global-section)
+about all the options you can use.
+
+### The `runners` section
+
+From the `[[runners]]` section, the most important part is the `executor` which
+must be set to `docker+machine`. Most of those settings are taken care of when
+you register the Runner for the first time.
+
+`limit` sets the maximum number of machines (running and idle) that this Runner
+will spawn. For more info check the [relationship between `limit`, `concurrent`
+and `IdleCount`](https://docs.gitlab.com/runner/configuration/autoscale.html#how-concurrent-limit-and-idlecount-generate-the-upper-limit-of-running-machines).
+
+Example:
+
+```toml
+[[runners]]
+  name = "gitlab-aws-autoscaler"
+  url = "<URL of your GitLab instance>"
+  token = "<Runner's token>"
+  executor = "docker+machine"
+  limit = 20
+```
+
+[Read more](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runners-section)
+about all the options you can use under `[[runners]]`.
+
+### The `runners.docker` section
+
+In the `[runners.docker]` section you can define the default Docker image to
+be used by the child Runners if it's not defined in [`.gitlab-ci.yml`](../../ci/yaml/README.md).
+By using `privileged = true`, all Runners will be able to run
+[Docker in Docker](../../ci/docker/using_docker_build.md#use-docker-in-docker-executor)
+which is useful if you plan to build your own Docker images via GitLab CI/CD.
+
+Next, we use `disable_cache = true` to disable the Docker executor's inner
+cache mechanism since we will use the distributed cache mode as described
+in the following section.
+
+Example:
+
+```toml
+  [runners.docker]
+    image = "alpine"
+    privileged = true
+    disable_cache = true
+```
+
+[Read more](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runners-docker-section)
+about all the options you can use under `[runners.docker]`.
+
+### The `runners.cache` section
+
+To speed up your jobs, GitLab Runner provides a cache mechanism where selected
+directories and/or files are saved and shared between subsequent jobs.
+While not required for this setup, it is recommended to use the distributed cache
+mechanism that GitLab Runner provides. Since new instances will be created on
+demand, it is essential to have a common place where the cache is stored.
+
+In the following example, we use Amazon S3:
+
+```toml
+  [runners.cache]
+    Type = "s3"
+    ServerAddress = "s3.amazonaws.com"
+    AccessKey = "<your AWS Access Key ID>"
+    SecretKey = "<your AWS Secret Access Key>"
+    BucketName = "<the bucket where your cache should be kept>"
+    BucketLocation = "us-east-1"
+    Shared = true
+```
+
+Here's some more info to further explore the cache mechanism:
+

+- [Deploying and using a cache server for GitLab Runner](https://docs.gitlab.com/runner/configuration/autoscale.html#distributed-runners-caching)
+- [How cache works](../../ci/yaml/README.md#cache)
+
+### The `runners.machine` section
+
+This is the most important part of the configuration and it's the one that
+tells GitLab Runner how and when to spawn new or remove old Docker Machine
+instances.
+
+We will focus on the AWS machine options, for the rest of the settings read
+about the:
+
+- [Autoscaling algorithm and the parameters it's based on](https://docs.gitlab.com/runner/configuration/autoscale.html#autoscaling-algorithm-and-parameters) - depends on the needs of your organization
+- [Off peak time configuration](https://docs.gitlab.com/runner/configuration/autoscale.html#off-peak-time-mode-configuration) - useful when there are regular time periods in your organization when no work is done, for example weekends
+
+Here's an example of the `runners.machine` section:
+
+```toml
+  [runners.machine]
+    IdleCount = 1
+    IdleTime = 1800
+    MaxBuilds = 10
+    OffPeakPeriods = [
+      "* * 0-9,18-23 * * mon-fri *",
+      "* * * * * sat,sun *"
+    ]
+    OffPeakIdleCount = 0
+    OffPeakIdleTime = 1200
+    MachineDriver = "amazonec2"
+    MachineName = "gitlab-docker-machine-%s"
+    MachineOptions = [
+      "amazonec2-access-key=XXXX",
+      "amazonec2-secret-key=XXXX",
+      "amazonec2-region=us-central-1",
+      "amazonec2-vpc-id=vpc-xxxxx",
+      "amazonec2-subnet-id=subnet-xxxxx",
+      "amazonec2-use-private-address=true",
+      "amazonec2-tags=runner-manager-name,gitlab-aws-autoscaler,gitlab,true,gitlab-runner-autoscale,true",
+      "amazonec2-security-group=docker-machine-scaler",
+      "amazonec2-instance-type=m4.2xlarge",
+    ]
+```
+
+The Docker Machine driver is set to `amazonec2` and the machine name has a
+standard prefix followed by `%s` (required) that is replaced by the ID of the
+child Runner: `gitlab-docker-machine-%s`.
+
+Now, depending on your AWS infrastructure, there are many options you can set up
+under `MachineOptions`. Below you can see the most common ones.
+
+| Machine option | Description |
+| -------------- | ----------- |
+| `amazonec2-access-key=XXXX` | The AWS access key of the user that has permissions to create EC2 instances, see [AWS credentials](#aws-credentials). |
+| `amazonec2-secret-key=XXXX` | The AWS secret key of the user that has permissions to create EC2 instances, see [AWS credentials](#aws-credentials). |
+| `amazonec2-region=eu-central-1` | The region to use when launching the instance. You can omit this entirely and the default `us-east-1` will be used. |
+| `amazonec2-vpc-id=vpc-xxxxx` | Your [VPC ID](https://docs.docker.com/machine/drivers/aws/#vpc-id) to launch the instance in. |
+| `amazonec2-subnet-id=subnet-xxxx` | The AWS VPC subnet ID. |
+| `amazonec2-use-private-address=true` | Use the private IP address of Docker Machines, but still create a public IP address. Useful to keep the traffic internal and avoid extra costs.|
+| `amazonec2-tags=runner-manager-name,gitlab-aws-autoscaler,gitlab,true,gitlab-runner-autoscale,true` | AWS extra tag key-value pairs, useful to identify the instances on the AWS console. The "Name" tag is set to the machine name by default. We set the "runner-manager-name" to match the Runner name set in `[[runners]]`, so that we can filter all the EC2 instances created by a specific manager setup. Read more about [using tags in AWS](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html). |
+| `amazonec2-security-group=docker-machine-scaler` | AWS VPC security group name, see [AWS security groups](#aws-security-groups). |
+| `amazonec2-instance-type=m4.2xlarge` | The instance type that the child Runners will run on. |
+
+TIP: **Tip:**
+Under `MachineOptions` you can add anything that the [AWS Docker Machine driver
+supports](https://docs.docker.com/machine/drivers/aws/#options). You are highly
+encouraged to read Docker's docs as your infrastructure setup may warrant
+different options to be applied.
+
+NOTE: **Note:**
+The child instances will use by default Ubuntu 16.04 unless you choose a
+different AMI ID by setting `amazonec2-ami`.
+
+NOTE: **Note:**
+If you specify `amazonec2-private-address-only=true` as one of the machine
+options, your EC2 instance won't get assigned a public IP. This is ok if your
+VPC is configured correctly with an Internet Gateway (IGW) and routing is fine,
+but it’s something to consider if you've got a more complex configuration. Read
+more in [Docker docs about VPC connectivity](https://docs.docker.com/machine/drivers/aws/#vpc-connectivity).
+
+[Read more](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runners-machine-section)
+about all the options you can use under `[runners.machine]`.
+
+### Getting it all together
+
+Here's the full example of `/etc/gitlab-runner/config.toml`:
+
+```toml
+concurrent = 10
+check_interval = 0
+
+[[runners]]
+  name = "gitlab-aws-autoscaler"
+  url = "<URL of your GitLab instance>"
+  token = "<Runner's token>"
+  executor = "docker+machine"
+  limit = 20
+  [runners.docker]
+    image = "alpine"
+    privileged = true
+    disable_cache = true
+  [runners.cache]
+    Type = "s3"
+    ServerAddress = "s3.amazonaws.com"
+    AccessKey = "<your AWS Access Key ID>"
+    SecretKey = "<your AWS Secret Access Key>"
+    BucketName = "<the bucket where your cache should be kept>"
+    BucketLocation = "us-east-1"
+    Shared = true
+  [runners.machine]
+    IdleCount = 1
+    IdleTime = 1800
+    MaxBuilds = 100
+    OffPeakPeriods = [
+      "* * 0-9,18-23 * * mon-fri *",
+      "* * * * * sat,sun *"
+    ]
+    OffPeakIdleCount = 0
+    OffPeakIdleTime = 1200
+    MachineDriver = "amazonec2"
+    MachineName = "gitlab-docker-machine-%s"
+    MachineOptions = [
+      "amazonec2-access-key=XXXX",
+      "amazonec2-secret-key=XXXX",
+      "amazonec2-region=us-central-1",
+      "amazonec2-vpc-id=vpc-xxxxx",
+      "amazonec2-subnet-id=subnet-xxxxx",
+      "amazonec2-use-private-address=true",
+      "amazonec2-tags=runner-manager-name,gitlab-aws-autoscaler,gitlab,true,gitlab-runner-autoscale,true",
+      "amazonec2-security-group=docker-machine-scaler",
+      "amazonec2-instance-type=m4.2xlarge",
+    ]
+```
+
+## Cutting down costs with Amazon EC2 Spot instances
+
+As [described by][spot] Amazon:
+
+>
+Amazon EC2 Spot instances allow you to bid on spare Amazon EC2 computing capacity.
+Since Spot instances are often available at a discount compared to On-Demand
+pricing, you can significantly reduce the cost of running your applications,
+grow your application’s compute capacity and throughput for the same budget,
+and enable new types of cloud computing applications.
+
+In addition to the [`runners.machine`](#the-runners-machine-section) options
+you picked above, in `/etc/gitlab-runner/config.toml` under the `MachineOptions`
+section, add the following:
+
+```toml
+    MachineOptions = [
+      "amazonec2-request-spot-instance=true",
+      "amazonec2-spot-price=0.03",
+      "amazonec2-block-duration-minutes=60"
+    ]
+```
+
+With this configuration, Docker Machines are created on Spot instances with a
+maximum bid price of $0.03 per hour and the duration of the Spot instance is
+capped at 60 minutes. The `0.03` number mentioned above is just an example, so
+be sure to check on the current pricing based on the region you picked.
+
+To learn more about Amazon EC2 Spot instances, visit the following links:
+
+- https://aws.amazon.com/ec2/spot/
+- https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-requests.html
+- https://aws.amazon.com/blogs/aws/focusing-on-spot-instances-lets-talk-about-best-practices/
+
+### Caveats of Spot instances
+
+While Spot instances is a great way to use unused resources and minimize the
+costs of your infrastructure, you must be aware of the implications.
+
+Running CI jobs on Spot instances may increase the failure rates because of the
+Spot instances pricing model. If the price exceeds your bid, the existing Spot
+instances will be immediately terminated and all your jobs on that host will fail.
+
+As a consequence, the auto-scale Runner would fail to create new machines while
+it will continue to request new instances. This eventually will make 60 requests
+and then AWS won't accept any more. Then once the Spot price is acceptable, you
+are locked out for a bit because the call amount limit is exceeded.
+
+If you encounter that case, you can use the following command in the bastion
+machine to see the Docker Machines state:
+
+```sh
+docker-machine ls -q --filter state=Error --format "{{.NAME}}"
+```
+
+NOTE: **Note:**
+There are some issues regarding making GitLab Runner gracefully handle Spot
+price changes, and there are reports of `docker-machine` attempting to
+continually remove a Docker Machine. GitLab has provided patches for both cases
+in the upstream project. For more information, see issues
+[#2771](https://gitlab.com/gitlab-org/gitlab-runner/issues/2771) and
+[#2772](https://gitlab.com/gitlab-org/gitlab-runner/issues/2772).
+
+## Conclusion
+
+In this guide we learned how to install and configure a GitLab Runner in
+autoscale mode on AWS.
+
+Using the autoscale feature of GitLab Runner can save you both time and money.
+Using the Spot instances that AWS provides can save you even more, but you must
+be aware of the implications. As long as your bid is high enough, there shouldn't
+be an issue.

+# Axios
+We use [axios][axios] to communicate with the server in Vue applications and most new code.
+
+In order to guarantee all defaults are set you *should not use `axios` directly*, you should import `axios` from `axios_utils`.
+
+## CSRF token
+All our request require a CSRF token.
+To guarantee this token is set, we are importing [axios][axios], setting the token, and exporting `axios` .
+
+This exported module should be used instead of directly using `axios` to ensure the token is set.
+
+## Usage
+```javascript
+  import axios from '~/lib/utils/axios_utils';
+
+  axios.get(url)
+    .then((response) => {
+      // `data` is the response that was provided by the server
+      const data = response.data;
+
+      // `headers` the headers that the server responded with
+      // All header names are lower cased
+      const paginationData = response.headers;
+    })
+    .catch(() => {
+      //handle the error
+    });
+```
+
+## Mock axios response on tests
+
+To help us mock the responses we need we use [axios-mock-adapter][axios-mock-adapter]
+
+
+```javascript
+  import axios from '~/lib/utils/axios_utils';
+  import MockAdapter from 'axios-mock-adapter';
+
+  let mock;
+  beforeEach(() => {
+    // This sets the mock adapter on the default instance
+    mock = new MockAdapter(axios);
+    // Mock any GET request to /users
+    // arguments for reply are (status, data, headers)
+    mock.onGet('/users').reply(200, {
+      users: [
+        { id: 1, name: 'John Smith' }
+      ]
+    });
+  });
+
+  afterEach(() => {
+    mock.reset();
+  });
+```
+
+### Mock poll requests on tests with axios
+
+Because polling function requires an header object, we need to always include an object as the third argument:
+
+```javascript
+  mock.onGet('/users').reply(200, { foo: 'bar' }, {});

-# Vue Resouce
-In Vue applications we use [vue-resource][vue-resource-repo] to communicate with the server.
-
-## HTTP Status Codes
-
-### `.json()`
-When making a request to the server, you will most likely need to access the body of the response.
-Use `.json()` to convert. Because `.json()` returns a Promise the follwoing structure should be used:
-
-  ```javascript
-  service.get('url')
-    .then(resp => resp.json())
-    .then((data) => {
-      this.store.storeData(data);
-    })
-    .catch(() => new Flash('Something went wrong'));
-  ```
-
-
-When using `Poll` (`app/assets/javascripts/lib/utils/poll.js`), the `successCallback` needs to handle `.json()` as a Promise:
-  ```javascript
-  successCallback: (response) => {
-    return response.json().then((data) => {
-      // handle the response
-    });
-  }
-  ```
-
-### 204
-Some endpoints - usually `delete` endpoints - return `204` as the success response.
-When handling `204 - No Content` responses, we cannot use `.json()` since it tries to parse the non-existant body content.
-
-When handling `204` responses, do not use `.json`, otherwise the promise will throw an error and will enter the `catch` statement:
-
-```javascript
-  Vue.http.delete('path')
-    .then(() => {
-      // success!
-    })
-    .catch(() => {
-      // handle error
-    })
-```
-
-## Headers
-Headers are being parsed into a plain object in an interceptor.
-In Vue-resource 1.x `headers` object was changed into an `Headers` object. In order to not change all old code, an interceptor was added.
-
-If you need to write a unit test that takes the headers in consideration, you need to include an interceptor to parse the headers after your test interceptor.
-You can see an example in `spec/javascripts/environments/environment_spec.js`:
-  ```javascript
-  import { headersInterceptor } from './helpers/vue_resource_helper';
-
-  beforeEach(() => {
-    Vue.http.interceptors.push(myInterceptor);
-    Vue.http.interceptors.push(headersInterceptor);
-  });
-
-  afterEach(() => {
-    Vue.http.interceptors = _.without(Vue.http.interceptors, myInterceptor);
-    Vue.http.interceptors = _.without(Vue.http.interceptors, headersInterceptor);
-  });
-  ```
-
-## CSRF token
-We use a Vue Resource interceptor to manage the CSRF token.
-`app/assets/javascripts/vue_shared/vue_resource_interceptor.js` holds all our common interceptors.
-Note: You don't need to load `app/assets/javascripts/vue_shared/vue_resource_interceptor.js`
-since it's already being loaded by `common_vue.js`.

+method is used on some tables that are very large on GitLab.com, which would
+cause other issues.
+
+## Updating an existing column
+
+To update an existing column to a particular value, you can use
+`update_column_in_batches` (`add_column_with_default` uses this internally to
+fill in the default value). This will split the updates into batches, so we
+don't update too many rows at in a single statement.
+
+This updates the column `foo` in the `projects` table to 10, where `some_column`
+is `'hello'`:
+
+```ruby
+update_column_in_batches(:projects, :foo, 10) do |table, query|
+  query.where(table[:some_column].eq('hello'))
+end
+```
+
+To perform a computed update, the value can be wrapped in `Arel.sql`, so Arel
+treats it as an SQL literal. The below example is the same as the one above, but
+the value is set to the product of the `bar` and `baz` columns:
+
+```ruby
+update_value = Arel.sql('bar * baz')
+
+update_column_in_batches(:projects, :foo, update_value) do |table, query|
+  query.where(table[:some_column].eq('hello'))
+end
+```
+
+Like `add_column_with_default`, there is a RuboCop cop to detect usage of this
+on large tables. In the case of `update_column_in_batches`, it may be acceptable
+to run on a large table, as long as it is only updating a small subset of the
+rows in the table, but do not ignore that without validating on the GitLab.com
+staging environment - or asking someone else to do so for you - beforehand.

+
+It is possible to generate diagrams and flowcharts from text using [Mermaid][mermaid].
+
+In order to generate a diagram or flowchart, you should write your text inside the `mermaid` block.
+
+Example:
+
+    ```mermaid
+    graph TD;
+      A-->B;
+      A-->C;
+      B-->D;
+      C-->D;
+    ```
+
+Becomes:
+
+```mermaid
+graph TD;
+  A-->B;
+  A-->C;
+  B-->D;
+  C-->D;
+```
+
+For details see the [Mermaid official page][mermaid].
