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)

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
