1、先下载Jenkins的镜像

[root@localhost ~]# docker pull jenkinsci/blueocean
Using default tag: latest
Trying to pull repository docker.io/jenkinsci/blueocean ... 
latest: Pulling from docker.io/jenkinsci/blueocean

Status: Downloaded newer image for docker.io/jenkinsci/blueocean:latest

2、查看镜像

[root@localhost ~]# docker images
REPOSITORY                      TAG                 IMAGE ID            CREATED             SIZE
docker.io/jenkinsci/blueocean   latest              745bd9d479f2        6 hours ago         716MB

3、将镜像启动成容器

docker run  \
--name=jenkins \
--privileged=true \
--restart=always \
--network=host \
-p 8080:8080  \
-p 5000:5000  \
-v /opt/jenkins:/var/jenkins_home  \
jenkinsci/blueocean

• –-name：容器名，此处命名为mysql
• --privileged=true 使用该参数，container内的root拥有真正的root权限
• --restart=always 自动重启容器
• --network=host 启动容器的时候使用 host 模式

[bsmessage type="common" color="yellow" title="执行以上命令时会提示"]touch: cannot touch '/var/jenkins_home/copy_reference_file.log': Permission denied
Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?[/bsmessage]
需要修改下目录权限, 因为当映射本地数据卷时，/opt/jenkins目录的拥有者为root用户，而容器中jenkins user的uid为1000
执行如下命令即可：

chown -R 1000:1000 /opt/jenkins

然后先停止并删除刚才启动的容器，重新执行启动命令：

docker run  \
--name=jenkins \
--privileged=true \
--restart=always \
--network=host \
-p 8080:8080  \
-p 5000:5000  \
-v /opt/jenkins:/var/jenkins_home  \
jenkinsci/blueocean

PS:第一次启动的时候正在加载jenkins大概会等待3-10分钟。

当终端出现以下内容时，就说明已经启动成功了

访问http://ip:8080,将上面的passwd复制粘贴进去就可以了

当所有的插件都下载安装完成之后，终端上ctrl+c停止容器，使其后台运行

[root@localhost ~]# docker start jenkins
jenkins
