在流水线中使用容器进行编译构建

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 bash

usermod -aG root jenkins

id jenkins

uid=1000(jenkins) gid=1000(jenkins) groups=1000(jenkins),0(root),1(daemon)
