创建jenkins目录及Dockerfile

$ mkdir jenkins && cd jenkins
$ touch Dockerfile
$ vim Dockerfile

编译并运行镜像

$ cd jenkins
$ docker build -t "test/jenkins:v1" .
$ docker run -d -p 8080:8080 --name jenkins --privileged test/jenkins:v1
###### 查看jenkins日志
$ docker logs -f jenkins
##### 看到 INFO: Jenkins is fully up and running 即表示运行成功
