如何使用docker部署Jenkins?按下面步骤走:
- 安装docker,mac用户可以使用
brew install docker
最好参照官网安装,一路next 2. 查看docker是否安装成功 执行:
docker info
出现下面这样就是成功了

- 新建目录
mkdir jenkins
- 新建两个文件,分别是Dockerfile和docker-compose.yml 他们的区别可以看一下
Dockerfile

docker-compose.yml:

restart: always
ports:

- '127.0.0.1:2002:50000'
volumes:
- '.:/var/jenkins_home' #数据持久目录,默认是当前目录
- 启动容器
docker-compose up -d
如果有报错的话,这个时候会提示,当有显示done时,就代表成功了。 6. 查看运行中容器
docker-compose ps
你会看到
