Jenkins-Spring

---

Deploying a dockerized Spring-boot application with Heroku CLI, Maven CLI, Docker CLI and Jenkins

---

Login to heroku container registry

$ heroku container:login

Create a new registry application:

• NB: You need to link this new application to the github repository housing your Spring-boot application, do this manually via the heroku dashboard: heroku-app-dashboard > Deploy > Deployment method

$ heroku create

Create an image of the registry application (locally):

$ heroku container:push web --app <generated-app-name>
$ heroku container:release web --app <generated-app-name>

Push the created image to dockerhub

$ docker login
$ docker tag <imageID> <DockerhubUsername>/<DockerhubRepoName>:<ImageTag>
$ docker push <DockerhubUsername>/<DockerhubRepoName>

The image will then be pulled from dockerhub, built and run by Jenkins:

Jenkinsfile:

pipeline {
    agent any
    
    stages {
        .....
        
        stage('D E P L O Y') {
            steps {
                sh 'make docker-pull-run'
            }
        }
    }
    
    ...
}

makefile:

....

docker-pull-run:
	docker run --rm -p 5850:9090 countach/springboot-docker-jenkins:jenky
	
  ...
