What can you do in Jenkins:

- Run shell script
- Check config with ansible

How to build Jenkins:
We use docker to build jenkins and use volume to keep config.
So it's easy for rebuild when your jenkins is dead and also easy for upgrade.

Build jenkins with docker

Pull docker image:
$ docker pull {url}

Create jenkins container:
$ docker run -itd --name jenkins -v jenkins:/var/jenkins_home --restart always -p {port}:8080 -e JAVA_OPTS=-Duser.timezone=Asia/Taipei -e TZ=Asia/Taipei -e LANG=en_US.UTF8 {url}

memo:
{port}:open up externally port number

Check your jenkins container:
$ docker ps -a

Open your browser and enter ip:port and you will see jenkins ask administrator password:

Use command to get administrator password:
$ docker logs jenkins

How to upgrade Jenkins:
$ docker stop jenkins
$ docker rm jenkins
