Docker 安装Jenkins

1.首先拉取镜像 docker pull jenkins
2.运行容器 

docker run -p 8080:8080 -p 50000:50000 -v $(which docker):/usr/bin/docker -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock --name testJenkins jenkins

3.以root用户进入容器 docker exec -it -u root testJenkins /bin/bash 

4.授予jenkins用户docker权限 chown jenkins: /var/run/docker.sock

5.检查docker ps之类的命令是否可用
