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 bash usermod -aG root jenkins  id jenkins uid=1000(jenkins) gid=1000(jenkins) groups=1000(jenkins),0(root),1(daemon)

调试流水线

1. pipeline {

2. agent {

3. docker {

4. image 'maven:3.6.3-jdk-8'

5. args '-v $HOME/.m2:/root/.m2'

6. }

7. }

8. stages {

9. stage('Build') {

10. steps {

11. sh 'mvn -v'

12. }

13. }

14. }

15. }

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 https://registry.npm.taobao.org                     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

npm打包慢问题：

2.1 挂载缓存卷

-v /var/jenkins_home/.npm:/root/.npm

2.2 设置淘宝源

npm config set registry https://registry.npm.taobao.org
