如何使用 Jenkinsfile 将 Docker 映像部署到某个 Docker 容器？

Question

I have a Jenkinsfile which build and deploys an Angular Image to Docker and stores it there - I use Portainer as an UI here. Now i want to add a deployment stage to my Jenkinsfile which deploys the Image to a certain container.

I tried serveral solutions from the internet but no of them worked for me.

Here is my Jenkinsfile:

    pipeline {

agent any
tools { 
    nodejs 'NodeJS 16.9.1'  
    dockerTool 'docker-19.03.9'  
}

environment {
    IMAGE = 'name-angular'
    VERSION = 'test'
}
stages {
    stage('Build image') {
        steps {
            script {
                sh 'npm install'
                sh 'npm run buildProd'
                IMAGE = readMavenPom().getArtifactId()
                VERSION = readMavenPom().getVersion()
                echo "Building image ${IMAGE}:${VERSION}..."
                dockerImage = docker.build("name:latest")
            }
        }
    }
    
    stage('Deploy image') {
        steps {
            echo 'Deploying image...'
          
        }
    }
    
    stage('Clean up') {
        steps {
            echo 'Cleaning up...'
        }
    }
}

}

As you see my deployment stage is completely empty because i even dont know how to start with this.

I think the dockerImage variable will not be transfer to the other stage, so you can call docker command directly. The below pipeline is an example, so you should fit this to your purpose.

pipeline {

    agent any

    tools { 
        nodejs 'NodeJS 16.9.1'  
        dockerTool 'docker-19.03.9'  
    }

    environment {
        IMAGE = readMavenPom().getArtifactId()
        VERSION = readMavenPom().getVersion()
    }

    stages {
        stage('Build image') {
            steps {
                sh 'npm install'
                sh 'npm run buildProd'

                echo "Building image ${IMAGE}:${VERSION}..."
                sh 'docker build -t ${IMAGE}:${VERSION} .'
            }
        }
  
        stage('Deploy image') {
            steps {
                echo 'Deploying image...'
                sh 'docker push ${IMAGE}:${VERSION}'
            }
        }
    
    post {
        always {
            sh 'docker rmi ${IMAGE}:${VERSION}'
        }
    }
}
