(It's status should be "running"). +The pipeline is split into 4 stages, each running a couple of jobs. + +![Pipeline stages](img/guide_pipeline_stages.png) + +In the **build** stage, the application is built into a Docker image and then +uploaded to your project's [Container Registry](../../user/project/container_registry.md) ([Auto Build](index.md#auto-build)). + +In the **test** stage, GitLab runs various checks on the application: + +- The `test` job runs unit and integration tests by detecting the language and + framework ([Auto Test](index.md#auto-test)) +- The `code_quality` job checks the code quality and is allowed to fail + ([Auto Code Quality](index.md#auto-code-quality)) **[STARTER]** +- The `container_scanning` job checks the Docker container if it has any + vulnerabilities and is allowed to fail ([Auto Container Scanning](index.md#auto-container-scanning)) +- The `dependency_scanning` job checks if the application has any dependencies + susceptible to vulnerabilities and is allowed to fail ([Auto Dependency Scanning](index.md#auto-dependency-scanning)) **[ULTIMATE]** +- The `sast` job runs static analysis on the current code to check for potential + security issues and is allowed to fail([Auto SAST](index.md#auto-sast)) **[ULTIMATE]** +- The `license_management` job searches the application's dependencies to determine each of their + licenses and is allowed to fail ([Auto License Management](index.md#auto-license-management)) **[ULTIMATE]** NOTE: **Note:** -If your ingress controller has been installed in a different way, you can find -how to get the external IP address in the -[Cluster documentation](../../user/project/clusters/index.md#getting-the-external-ip-address). +As you might have noticed, all jobs except `test` are allowed to fail in the +test stage. + +The **production** stage is run after the tests and checks finish, and it automatically +deploys the application in Kubernetes ([Auto Deploy](index.md#auto-deploy)). + +Lastly, in the **performance** stage, some performance tests will run +on the deployed application +([Auto Browser Performance Testing](index.md#auto-browser-performance-testing)). **[PREMIUM]** + +--- -Use this IP address to configure your DNS. This part heavily depends on your -preferences and domain provider. But in case you are not sure, just create an -A record with a wildcard host like `*.<your-domain>`. +The URL for the deployed application can be found under the **Environments** +page where you can also monitor your application. Let's explore that. + +### Monitoring + +Now that the application is successfully deployed, let's navigate to its +website. First, go to **Operations > Environments**. + +![Environments](img/guide_environments.png) + +In **Environments** you can see some details about the deployed +applications. In the rightmost column for the production environment, you can make use of the three icons: + +- The first icon will open the URL of the application that is deployed in + production. It's a very simple page, but the important part is that it works! +- The next icon with the small graph will take you to the metrics page where + Prometheus collects data about the Kubernetes cluster and how the application + affects it (in terms of memory/CPU usage, latency, etc.). + + ![Environments metrics](img/guide_environments_metrics.png) + +- The third icon is the [web terminal](../../ci/environments.md#web-terminals) + and it will open a terminal session right inside the container where the + application is running. + +Right below, there is the +[Deploy Board](https://docs.gitlab.com/ee/user/project/deploy_boards.md). +The squares represent pods in your Kubernetes cluster that are associated with +the given environment. Hovering above each square you can see the state of a +deployment and clicking a square will take you to the pod's logs page. + +TIP: **Tip:** +There is only one pod hosting the application at the moment, but you can add +more pods by defining the [`REPLICAS` variable](index.md#environment-variables) +under **Settings > CI/CD > Variables**. + +### Working with branches + +Following the [GitLab flow](../../workflow/gitlab_flow.md#working-with-feature-branches) +let's create a feature branch that will add some content to the application. + +Under your repository, navigate to the following file: `app/views/welcome/index.html.erb`. +By now, it should only contain a paragraph: `<p>You're on Rails!</p>`, so let's +start adding content. Let's use GitLab's [Web IDE](../../user/project/web_ide/index.md) to make the change. Once +you're on the Web IDE, make the following change: + +```html +<p>You're on Rails! Powered by GitLab Auto DevOps.</p> +``` + +Stage the file, add a commit message, and create a new branch and a merge request +by clicking **Commit**. + +![Web IDE commit](img/guide_ide_commit.png) + +Once you submit the merge request, you'll see the pipeline running. This will +run all the jobs as [described previously](#deploying-the-application), as well +a few more that run only on branches other than `master`. + +![Merge request](img/guide_merge_request.png) + +After a few minutes you'll notice that there was a failure in a test. +This means there's a test that was 'broken' by our change. +Navigating into the `test` job that failed, you can see what the broken test is: + +``` +Failure: +WelcomeControllerTest#test_should_get_index [/app/test/controllers/welcome_controller_test.rb:7]: +<You're on Rails!> expected but was +<You're on Rails! Powered by GitLab Auto DevOps.>.. +Expected 0 to be >= 1. + +bin/rails test test/controllers/welcome_controller_test.rb:4 +``` -Use `nslookup minimal-ruby-app-staging.<yourdomain>` to confirm that domain is -assigned to the cluster IP. +Let's fix that: -## Set up Auto DevOps +1. Back to the merge request, click the **Web IDE** button. +1. Find the `test/controllers/welcome_controller_test.rb` file and open it. +1. Change line 7 to say `You're on Rails! Powered by GitLab Auto DevOps.` +1. Click **Commit**. +1. On your left, under "Unstaged changes", click the little checkmark icon + to stage the changes. +1. Write a commit message and click **Commit**. -In your GitLab.com project, go to **Settings > CI/CD** and find the Auto DevOps -section. Select "Enable Auto DevOps", add in your base domain, and save. +Now, if you go back to the merge request you should not only see the test passing, +but also the application deployed as a [review app](index.md#auto-review-apps). You +can visit it by following the URL in the merge request. The changes that we +previously made should be there. -Next, a pipeline needs to be triggered. Since the test project doesn't have a -`.gitlab-ci.yml`, you need to either push a change to the repository or -manually visit `https://gitlab.com/<username>/minimal-ruby-app/pipelines/new`, -where `<username>` is your username. +![Review app](img/guide_merge_request_review_app.png) -This will create a new pipeline with several jobs: `build`, `test`, `code_quality`, -and `production`. The `build` job will create a Docker image with your new -change and push it to the Container Registry. The `test` job will test your -changes, whereas the `code_quality` job will run static analysis on your changes. -Finally, the `production` job will deploy your changes to a production application. +Once you merge the merge request, the pipeline will run on the `master` branch, +and the application will be eventually deployed straight to production. -Once the deploy job succeeds you should be able to see your application by -visiting the Kubernetes dashboard. Select the namespace of your project, which -will look like `minimal-ruby-app-23`, but with a unique ID for your project, -and your app will be listed as "production" under the Deployment tab. +## Conclusion -Once its ready, just visit `http://minimal-ruby-app.example.com` to see the -famous "Hello, world!"! +After implementing this project, you should now have a solid understanding of the basics of Auto DevOps. +We started from building and testing to deploying and monitoring an application +all within GitLab. Despite its automatic nature, Audo DevOps can also be configured +and customized to fit your workflow.
