如何在流水线中使用Docker容器进行编译构建

如何在流水线中使用Docker容器进行编译构建

配置DockerInDocker

配置JenkinsMaster挂载Docker

docker run --name jenkins -itd \ -p 8081:8080 \ -p 50000:50000 \ -v ~/jenkins:/var/jenkins_home \ -v /var/run/docker.sock:/var/run/docker.sock \ -v /usr/local/bin/docker:/usr/bin/docker \ jenkins/jenkins:lts

解决权限问题/以root用户运行

docker exec -it -u root jenkins bashusermod -aG root jenkins id jenkinsuid=1000(jenkins) gid=1000(jenkins) groups=1000(jenkins),0(root),1(daemon)

调试流水线

pipeline { agent { docker { image 'maven:3.6.3-jdk-8' args '-v $HOME/.m2:/root/.m2' } } stages { stage('Build') { steps { sh 'mvn -v' } } }}

每个阶段指定不同的Docker容器运行

pipeline { agent none stages { stage('ServiceBuild') { agent { docker { image 'maven:3.6.3-jdk-8' args '-v $HOME/.m2:/root/.m2' } } steps { sh 'mvn -v && sleep 15' } } stage('WebBuild') { agent { docker { image 'node:7-alpine' args '-v $HOME/.m2:/root/.m2' } } steps { sh 'node -v && sleep 15' } } }}

前端流水线

pipeline { agent none stages { stage('WebBuild') { agent { docker { image 'node:10.19.0-alpine' args '-u 0:0 -v /var/jenkins_home/.npm:/root/.npm' } } steps { sh """ id ls /root/.npm ls /root/ -a npm config set unsafe-perm=true npm config list npm config set cache /root/.npm #npm config set registry npm config list ls npm install --unsafe-perm=true && npm run build && ls -l dist/ && sleep 15 """ } } }}

FAQ

npm构建权限问题：使用root用户构建。设置容器运行用户 -u 0:0
