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

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
