All the code for this project can be found in this [GitLab repo](https://gitlab.com/gitlab-examples/spring-gitlab-cf-deploy-demo). In case you're interested in deploying Spring Boot applications to Kubernetes using GitLab CI/CD, read through the blog post [Continuous Delivery of a Spring Boot application with GitLab CI and Kubernetes](https://about.gitlab.com/2016/12/14/continuous-delivery-of-a-spring-boot-application-with-gitlab-ci-and-kubernetes/). ## Requirements _We assume you are familiar with Java, GitLab, Cloud Foundry, and GitLab CI/CD._ To follow along with this tutorial you will need the following: - An account on [Pivotal Web Services (PWS)](https://run.pivotal.io/) or any other Cloud Foundry instance - An account on GitLab NOTE: **Note:** You will need to replace the `api.run.pivotal.io` URL in the all below commands with the [API URL](https://docs.cloudfoundry.org/running/cf-api-endpoint.html) of your CF instance if you're not deploying to PWS. ## Create your project To create your Spring Boot application you can use the Spring template in GitLab when creating a new project: ![New Project From Template](img/create_from_template.png) ## Configure the deployment to Cloud Foundry To deploy to Cloud Foundry we need to add a `manifest.yml` file. This is the configuration for the CF CLI we will use to deploy the application. We will create this in the root directory of our project with the following content: ```yaml --- applications: - name: gitlab-hello-world random-route: true memory: 1G path: target/demo-0.0.1-SNAPSHOT.jar ``` ## Configure GitLab CI/CD to deploy your application Now we need to add the GitLab CI/CD configuration file ([`.gitlab-ci.yml`](../../yaml/README.md)) to our project's root. This is how GitLab figures out what commands need to be run whenever code is pushed to our repository. We will add the following `.gitlab-ci.yml` file to the root directory of the repository, GitLab will detect it automatically and run the steps defined once we push our code: ```yaml image: java:8 stages: - build - deploy build: stage: build script: ./mvnw package artifacts: paths: - target/demo-0.0.1-SNAPSHOT.jar production: stage: deploy script: - curl --location "https://cli.run.pivotal.io/stable?release=linux64-binary&source=github" | tar zx - ./cf login -u $CF_USERNAME -p $CF_PASSWORD -a api.run.pivotal.io - ./cf push only: - master ``` We've used the `java:8` [docker image](../../docker/using_docker_images.md) to build our application as it provides the up-to-date Java 8 JDK on [Docker Hub](https://hub.docker.com/). We've also added the [`only` clause](../../yaml/README.md#only-and-except-simplified) to ensure our deployments only happen when we push to the master branch. Now, since the steps defined in `.gitlab-ci.yml` require credentials to login to CF, you'll need to add your CF credentials as [environment variables](../../variables/README.md#predefined-variables-environment-variables) on GitLab CI/CD. To set the environment variables, navigate to your project's **Settings > CI/CD** and expand **Variables**. Name the variables `CF_USERNAME` and `CF_PASSWORD` and set them to the correct values. ![Variable Settings in GitLab](img/cloud_foundry_variables.png) Once set up, GitLab CI/CD will deploy your app to CF at every push to your repository's deafult branch. To see the build logs or watch your builds running live, navigate to **CI/CD > Pipelines**. CAUTION: **Caution:** It is considered best practice for security to create a separate deploy user for your application and add its credentials to GitLab instead of using a developer's credentials. To start a manual deployment in GitLab go to **CI/CD > Pipelines** then click on **Run Pipeline**. Once the app is finished deploying it will display the URL of your application in the logs for the `production` job like: ```shell requested state: started instances: 1/1 usage: 1G x 1 instances urls: gitlab-hello-world-undissembling-hotchpot.cfapps.io last uploaded: Mon Nov 6 10:02:25 UTC 2017 stack: cflinuxfs2 buildpack: client-certificate-mapper=1.2.0_RELEASE container-security-provider=1.8.0_RELEASE java-buildpack=v4.5-offline-https://github.com/cloudfoundry/java-buildpack.git#ffeefb9 java-main java-opts jvmkill-agent=1.10.0_RELEASE open-jdk-like-jre=1.8.0_1... state since cpu memory disk details #0 running 2017-11-06 09:03:22 PM 120.4% 291.9M of 1G 137.6M of 1G ``` You can then visit your deployed application (for this example, `https://gitlab-hello-world-undissembling-hotchpot.cfapps.io/`) and you should see the "Spring is here!" message.
