Jenkins: 与docker一起协作

lihongjie0209 commented 4 years ago

使用docker启动一个jenkins


docker run \
  --rm \
  -u root \
  -p 8080:8080 \
  -v jenkins-data:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$HOME":/home \
  jenkinsci/blueocean

关键是 -v /var/run/docker.sock:/var/run/docker.sock, 这样的话jenkins可以通过这个socket与宿主机上的docker通信。

使用docker运行pipeline

Jenkinsfile (Declarative Pipeline)
pipeline {
    agent {
        docker { image 'node:7-alpine' }
    }
    stages {
        stage('Test') {
            steps {
                sh 'node --version'
            }
        }
    }
}

Using multiple containers

It has become increasingly common for code bases to rely on multiple, different, technologies. For example, a repository might have both a Java-based back-end API implementation and a JavaScript-based front-end implementation. Combining Docker and Pipeline allows a Jenkinsfile to use multiple types of technologies by combining the agent {} directive, with different stages.

Jenkinsfile (Declarative Pipeline)

pipeline {
    agent none
    stages {
        stage('Back-end') {
            agent {
                docker { image 'maven:3-alpine' }
            }
            steps {
                sh 'mvn --version'
            }
        }
        stage('Front-end') {
            agent {
                docker { image 'node:14-alpine' }
            }
            steps {
                sh 'node --version'
            }
        }
    }
}
