DevOps - CI

Preparation

1. Start the devops-ci VM in the BME VIK Cloud (Smallville)
2. Create new GitHub repository for the demo SpringBoot RESTFul application

git clone https://github.com/szatmari/devops-ci.git
git remote set-url myorigin YOUR_GIT_URL
git pull myorigin master --allow-unrelated-histories
git push -u myorigin master

Gradle

1. Run the SpringBoot REST App

./gradlew bootRun

2. Test the application:

curl http://localhost:8088/greeting?name=Zoltan

3. Add dependency (src/main/java/hello/Greeting.java)

import org.joda.time.LocalTime;
...
    public String getContent() {
        LocalTime currentTime = new LocalTime();
        return content +" " + currentTime;
    }

4. Test the application again

curl http://localhost:8088/greeting?name=Zoltan

5. Map the port 8088 to the public interface in the BME Cloud Manager
6. Test the application on the generated URL using a browser

Jenkins

1. Map the port 8080 to the public interface in the BME Cloud Manager
2. Visit the generated endpoint
3. Create a new freestyle job
   • Set your GitHub link to your project
   • Configure SCM: git
   • Add your repository URL
   • Set the "Branches to build" property to "*/master"
   • Add "Invoke gradle script" to the Build section
   • Set the gradle task: "build"
   • Add a Post Build action: Publish Junit test results
   • Set the path of the "Test report XMLs" to "build/test-results/test/*.xml"
4. Set build trigger: Poll SCM "* * * * *"
5. Add a new build task to do deployment: "Execute shell"

docker-compose up -d --force-recreate

Travis + Heroku

1. Visit and login to https://travis-ci.org/ using your GitHub account
2. Open your profile page and connect your GitHub Rpository (enable) to Travis https://travis-ci.org/account/repositories
3. Add, commit and push the travis.yml file to your repository

language: java
jdk: openjdk8

4. Add Procfile for Heroku deployment

web java -Dserver.port=$PORT -jar target/gs-rest-service-0.1.0.jar

5. Add deploy steps to the .travis,yml

language: java
jdk: openjdk8

deploy:
  provider: heroku
  api_key: paceholder
  app: devops-ci

6. Generate secure API key for Heroku deployment for this repository

travis encrypt paste-your-api-key-here --add deploy.api_key --org

7. Check the app on your Heroku URL
