+In this article, we will show how you can leverage the power of [GitLab CI/CD](https://about.gitlab.com/features/gitlab-ci-cd/)
+to build a [Maven](https://maven.apache.org/) project, deploy it to [Artifactory](https://www.jfrog.com/artifactory/), and then use it from another Maven application as a dependency.
+
+You'll create two different projects:
+
+- `simple-maven-dep`: the app built and deployed to Artifactory (available at https://gitlab.com/gitlab-examples/maven/simple-maven-dep)
+- `simple-maven-app`: the app using the previous one as a dependency (available at https://gitlab.com/gitlab-examples/maven/simple-maven-app)
+
+We assume that you already have a GitLab account on [GitLab.com](https://gitlab.com/), and that you know the basic usage of Git and [GitLab CI/CD](https://about.gitlab.com/features/gitlab-ci-cd/).
+We also assume that an Artifactory instance is available and reachable from the internet, and that you have valid credentials to deploy on it.
+
+## Create the simple Maven dependency
+
+First of all, you need an application to work with: in this specific case we will
+use a simple one, but it could be any Maven application. This will be the
+dependency you want to package and deploy to Artifactory, in order to be
+available to other projects.
+
+### Prepare the dependency application
+
+For this article you'll use a Maven app that can be cloned from our example
+project:
+
+1. Log in to your GitLab account
+1. Create a new project by selecting **Import project from ➔ Repo by URL**
+1. Add the following URL:
+
+    ```
+    https://gitlab.com/gitlab-examples/maven/simple-maven-dep.git
+    ```
+1. Click **Create project**
+
+This application is nothing more than a basic class with a stub for a JUnit based test suite.
+It exposes a method called `hello` that accepts a string as input, and prints a hello message on the screen.
+
+The project structure is really simple, and you should consider these two resources:
+
+- `pom.xml`: project object model (POM) configuration file
+- `src/main/java/com/example/dep/Dep.java`: source of our application
+
+### Configure the Artifactory deployment
+
+The application is ready to use, but you need some additional steps to deploy it to Artifactory:
+
+1. Log in to Artifactory with your user's credentials.
+1. From the main screen, click on the `libs-release-local` item in the **Set Me Up** panel.
+1. Copy to clipboard the configuration snippet under the **Deploy** paragraph.
+1. Change the `url` value in order to have it configurable via secret variables.
+1. Copy the snippet in the `pom.xml` file for your project, just after the
+   `dependencies` section. The snippet should look like this:
+
+    ```xml
+    <distributionManagement>
+      <repository>
+        <id>central</id>
+        <name>83d43b5afeb5-releases</name>
+        <url>${env.MAVEN_REPO_URL}/libs-release-local</url>
+      </repository>
+    </distributionManagement>
+    ```
+
+Another step you need to do before you can deploy the dependency to Artifactory
+is to configure the authentication data. It is a simple task, but Maven requires
+it to stay in a file called `settings.xml` that has to be in the `.m2` subdirectory
+in the user's homedir.
+
+Since you want to use GitLab Runner to automatically deploy the application, you
+should create the file in the project's home directory and set a command line
+parameter in `.gitlab-ci.yml` to use the custom location instead of the default one:
+
+1. Create a folder called `.m2` in the root of your repository
+1. Create a file called `settings.xml` in the `.m2` folder
+1. Copy the following content into a `settings.xml` file:
+
+    ```xml
+    <settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd"
+        xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
+      <servers>
+        <server>
+          <id>central</id>
+          <username>${env.MAVEN_REPO_USER}</username>
+          <password>${env.MAVEN_REPO_PASS}</password>
+        </server>
+      </servers>
+    </settings>
+    ```
+
+    Username and password will be replaced by the correct values using secret variables.
+
+### Configure GitLab CI/CD for `simple-maven-dep`
+
+Now it's time we set up [GitLab CI/CD](https://about.gitlab.com/features/gitlab-ci-cd/) to automatically build, test and deploy the dependency!
+
+GitLab CI/CD uses a file in the root of the repo, named `.gitlab-ci.yml`, to read the definitions for jobs
+that will be executed by the configured GitLab Runners. You can read more about this file in the [GitLab Documentation](https://docs.gitlab.com/ee/ci/yaml/).
+
+First of all, remember to set up secret variables for your deployment. Navigate to your project's **Settings > CI/CD** page
+and add the following secret variables (replace them with your current values, of course):
+
+- **MAVEN_REPO_URL**: `http://artifactory.example.com:8081/artifactory` (your Artifactory URL)
+- **MAVEN_REPO_USER**: `gitlab` (your Artifactory username)
+- **MAVEN_REPO_PASS**: `AKCp2WXr3G61Xjz1PLmYa3arm3yfBozPxSta4taP3SeNu2HPXYa7FhNYosnndFNNgoEds8BCS` (your Artifactory Encrypted Password)
+
+Now it's time to define jobs in `.gitlab-ci.yml` and push it to the repo:
+
+```yaml
+image: maven:latest
+
+variables:
+  MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
+  MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"
+
+cache:
+  paths:
+    - .m2/repository/
+    - target/
+
+build:
+  stage: build
+  script:
+    - mvn $MAVEN_CLI_OPTS compile
+
+test:
+  stage: test
+  script:
+    - mvn $MAVEN_CLI_OPTS test
+
+deploy:
+  stage: deploy
+  script:
+    - mvn $MAVEN_CLI_OPTS deploy
+  only:
+    - master
+```
+
+GitLab Runner will use the latest [Maven Docker image](https://hub.docker.com/_/maven/), which already contains all the tools and the dependencies you need to manage the project,
+in order to run the jobs.
+
+Environment variables are set to instruct Maven to use the `homedir` of the repo instead of the user's home when searching for configuration and dependencies.
+
+Caching the `.m2/repository folder` (where all the Maven files are stored), and the `target` folder (where our application will be created), is useful for speeding up the process
+by running all Maven phases in a sequential order, therefore, executing `mvn test` will automatically run `mvn compile` if necessary.
+
+Both `build` and `test` jobs leverage the `mvn` command to compile the application and to test it as defined in the test suite that is part of the application.
+
+Deploy to Artifactory is done as defined by the secret variables we have just set up.
+The deployment occurs only if we're pushing or merging to `master` branch, so that the development versions are tested but not published.
+
+Done! Now you have all the changes in the GitLab repo, and a pipeline has already been started for this commit. In the **Pipelines** tab you can see what's happening.
+If the deployment has been successful, the deploy job log will output:
+
+```
+[INFO] ------------------------------------------------------------------------
+[INFO] BUILD SUCCESS
+[INFO] ------------------------------------------------------------------------
+[INFO] Total time: 1.983 s
+```
+
+>**Note**:
+the `mvn` command downloads a lot of files from the internet, so you'll see a lot of extra activity in the log the first time you run it.
+
+Yay! You did it! Checking in Artifactory will confirm that you have a new artifact available in the `libs-release-local` repo.
+
+## Create the main Maven application
+
+Now that you have the dependency available on Artifactory, it's time to use it!
+Let's see how we can have it as a dependency to our main application.
+
+### Prepare the main application
+
+We'll use again a Maven app that can be cloned from our example project:
+
+1. Create a new project by selecting **Import project from ➔ Repo by URL**
+1. Add the following URL:
+
+    ```
+    https://gitlab.com/gitlab-examples/maven/simple-maven-app.git
+    ```
+1. Click **Create project**
+
+This one is a simple app as well. If you look at the `src/main/java/com/example/app/App.java`
+file you can see that it imports the `com.example.dep.Dep` class and calls the `hello` method passing `GitLab` as a parameter.
+
+Since Maven doesn't know how to resolve the dependency, you need to modify the configuration:
+
+1. Go back to Artifactory
+1. Browse the `libs-release-local` repository
+1. Select the `simple-maven-dep-1.0.jar` file
+1. Find the configuration snippet from the **Dependency Declaration** section of the main panel
+1. Copy the snippet in the `dependencies` section of the `pom.xml` file.
+   The snippet should look like this:
+
+    ```xml
+    <dependency>
+      <groupId>com.example.dep</groupId>
+      <artifactId>simple-maven-dep</artifactId>
+      <version>1.0</version>
+    </dependency>
+    ```
+
+### Configure the Artifactory repository location
+
+At this point you defined the dependency for the application, but you still miss where you can find the required files.
+You need to create a `.m2/settings.xml` file as you did for the dependency project, and let Maven know the location using environment variables.
+
+Here is how you can get the content of the file directly from Artifactory:
+
+1. From the main screen, click on the `libs-release-local` item in the **Set Me Up** panel
+1. Click on **Generate Maven Settings**
+1. Click on **Generate Settings**
+1. Copy to clipboard the configuration file
+1. Save the file as `.m2/settings.xml` in your repo
+
+Now you are ready to use the Artifactory repository to resolve dependencies and use `simple-maven-dep` in your main application!
+
+### Configure GitLab CI/CD for `simple-maven-app`
+
+You need a last step to have everything in place: configure the `.gitlab-ci.yml` file for this project, as you already did for `simple-maven-dep`.
+
+You want to leverage [GitLab CI/CD](https://about.gitlab.com/features/gitlab-ci-cd/) to automatically build, test and run your awesome application,
+and see if you can get the greeting as expected!
+
+All you need to do is to add the following `.gitlab-ci.yml` to the repo:
+
+```yaml
+image: maven:latest
+
+stages:
+  - build
+  - test
+  - run
+
+variables:
+  MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
+  MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"
+
+cache:
+  paths:
+    - .m2/repository/
+    - target/
+
+build:
+  stage: build
+  script:
+    - mvn $MAVEN_CLI_OPTS compile
+
+test:
+  stage: test
+  script:
+    - mvn $MAVEN_CLI_OPTS test
+
+run:
+  stage: run
+  script:
+    - mvn $MAVEN_CLI_OPTS package
+    - mvn $MAVEN_CLI_OPTS exec:java -Dexec.mainClass="com.example.app.App"
+```
+
+It is very similar to the configuration used for `simple-maven-dep`, but instead of the `deploy` job there is a `run` job.
+Probably something that you don't want to use in real projects, but here it is useful to see the application executed automatically.
+
+And that's it! In the `run` job output log you will find a friendly hello to GitLab!
+
+## Conclusion
+
+In this article we covered the basic steps to use an Artifactory Maven repository to automatically publish and consume artifacts.
+
+A similar approach could be used to interact with any other Maven compatible Binary Repository Manager.
+Obviously, you can improve these examples, optimizing the `.gitlab-ci.yml` file to better suit your needs, and adapting to your workflow.

+The goal of this accord is to make sure we are all on the same page. 
 
+1. When writing Vue, you may not use jQuery in your application. 
+1.1 If you need to grab data from the DOM, you may query the DOM 1 time while bootstrapping your application to grab data attributes using `dataset`. You can do this without jQuery.
+1.2 You may use a jQuery dependency in Vue.js following [this example from the docs](https://vuejs.org/v2/examples/select2.html). 
+1.3 If an outside jQuery Event needs to be listen to inside the Vue application, you may use jQuery event listeners.
+1.4 We will avoid adding new jQuery events when they are not required. Instead of adding new jQuery events take a look at [different methods to do the same task](https://vuejs.org/v2/api/#vm-emit).
+
+1. You may query the `window` object 1 time, while bootstrapping your application for application specific data (e.g. `scrollTo` is ok to access anytime). Do this access during the bootstrapping of your application.
+
+1. You may have a temporary but immediate need to create technical debt by writing code that does not follow our standards, to be refactored later. Maintainers need to be ok with the tech debt in the first place. An issue should be created for that tech debt to evaluate it further and discuss. In the coming months you should fix that tech debt, with it's priority to be determined by maintainers.
+
+1. When creating tech debt you must write the tests for that code before hand and those tests may not be rewritten. e.g. jQuery tests rewritten to Vue tests.
+
+1. You may choose to use VueX as a centralized state management. If you choose not to use VueX, you must use the *store pattern* which can be found in the [Vue.js documentation](https://vuejs.org/v2/guide/state-management.html#Simple-State-Management-from-Scratch).
+
+1. Once you have chosen a centralized state management solution you must use it for your entire application. i.e. Don't mix and match your state management solutions.

+# Monitoring NGINX Ingress Controller
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/13438) in GitLab 9.5
+
+GitLab has support for automatically detecting and monitoring the Kubernetes NGINX ingress controller. This is provided by leveraging the built in Prometheus metrics included in [version 0.9.0](https://github.com/kubernetes/ingress/blob/master/controllers/nginx/Changelog.md#09-beta1) of the ingress.
+
+## Metrics supported
+

+| HTTP Error Rate (HTTP Errors / sec) | sum(rate(nginx_upstream_responses_total{status_code="5xx", upstream=~"%{kube_namespace}-%{ci_environment_slug}-.*"}[2m])) |
+
+## Configuring Prometheus to monitor for NGINX ingress metrics
+
+The easiest way to get started is to use at least version 0.9.0 of [NGINX ingress](https://github.com/kubernetes/ingress/tree/master/controllers/nginx). If you are using NGINX as your Kubernetes ingress, there is [direct support](https://github.com/kubernetes/ingress/pull/423) for enabling Prometheus monitoring in the 0.9.0 release.
+
+If you have deployed with the [gitlab-omnibus](https://docs.gitlab.com/ee/install/kubernetes/gitlab_omnibus.md) Helm chart, these metrics will be automatically enabled and annotated for Prometheus monitoring.
+
+## Specifying the Environment label
+
+In order to isolate and only display relevant metrics for a given environment
+however, GitLab needs a method to detect which labels are associated. To do this, GitLab will search metrics with appropriate labels. In this case, the `upstream` label must be of the form `<Kubernetes Namespace>-<CI_ENVIRONMENT_SLUG>-*`.
+
+If you have used [Auto Deploy](https://docs.gitlab.com/ee/ci/autodeploy/index.html) to deploy your app, this format will be used automatically and metrics will be detected with no action on your part.

+You can manage the groups and users and their access levels in all of your

+
+You should have `master` or `owner` [permissions](../../permissions.md) to add
+or import a new user to your project.
+
+To view, edit, add, and remove project's members, go to your
+project's **Settings > Members**.

+# Share Projects with other Groups
+
+You can share projects with other [groups](../../group/index.md). This makes it
+possible to add a group of users to a project with a single action.
+
+## Groups as collections of users
+
+Groups are used primarily to [create collections of projects](../user/group/index.md), but you can also
+take advantage of the fact that groups define collections of _users_, namely the group
+members.
+
+## Sharing a project with a group of users
+
+The primary mechanism to give a group of users, say 'Engineering', access to a project,
+say 'Project Acme', in GitLab is to make the 'Engineering' group the owner of 'Project
+Acme'.  But what if 'Project Acme' already belongs to another group, say 'Open Source'?
+This is where the group sharing feature can be of use.
+
+To share 'Project Acme' with the 'Engineering' group, go to the project settings page for 'Project Acme' and use the left navigation menu to go to the 'Groups' section.
+
+![The 'Groups' section in the project settings screen](img/share_project_with_groups.png)
+
+Now you can add the 'Engineering' group with the maximum access level of your choice.
+After sharing 'Project Acme' with 'Engineering', the project is listed on the group dashboard.
+
+!['Project Acme' is listed as a shared project for 'Engineering'](img/other_group_sees_shared_project.png)
+
+## Maximum access level
+
+!['Project Acme' is shared with 'Engineering' with a maximum access level of 'Developer'](img/max_access_level.png)
+
+In the screenshot above, the maximum access level of 'Developer' for members from 'Engineering' means that users with higher access levels in 'Engineering' ('Master' or 'Owner') will only have 'Developer' access to 'Project Acme'.
+
+## Share project with group lock (EES/EEP)
+
+In [GitLab Enterprise Edition Starter](https://about.gitlab.com/gitlab-ee/)
+it is possible to prevent projects in a group from [sharing
+a project with another group](../members/share_project_with_groups.md).
+This allows for tighter control over project access.
+
+Learn more about [Share with group lock](https://docs.gitlab.com/ee/user/group/index.html#share-with-group-lock-ees-eep).

-
-When in a Project -> Settings, you will find Features on the bottom of the page that you can toggle.
-
-Below you will find a more elaborate explanation of each of these.
-
-## Issues
-
-Issues is a really powerful, but lightweight issue tracking system.
-
-You can make tickets, assign them to people, file them under milestones, order them with labels and have discussion in them.
-
-They integrate deeply into GitLab and are easily referenced from anywhere by using `#` and the issue number.
-
-## Merge Requests
-
-Using a merge request, you can review and discuss code before it is merged in the branch of your code.
-
-As with issues, it can be assigned; people, issues, etc. can be referenced; milestones attached.
-
-We see it as an integral part of working together on code and couldn't work without it.
-
-## Wiki
-
-This is a separate system for documentation, built right into GitLab.
-
-It is source controlled and is very convenient if you don't want to keep you documentation in your source code, but you do want to keep it in your GitLab project.
-
-[Read more about Wikis.](../user/project/wiki/index.md)
-
-## Snippets
-
-Snippets are little bits of code or text.
-
-This is a nice place to put code or text that is used semi-regularly within the project, but does not belong in source control.
-
-For example, a specific config file that is used by the team that is only valid for the people that work on the code.

-## Git LFS
-
->**Note:** Project-specific LFS setting was added on 8.12 and is available only to admins.
-
-Git Large File Storage allows you to easily manage large binary files with Git.
-With this setting admins can better control which projects are allowed to use
