docker安装jenkins

1.下载镜像

docker pull jenkins/jenkins

2.创建挂载目录并授权

mkdir docker_vm
chmod 777 /usr/local/application/docker_vm

2.挂载并启动

docker run -d -p 10240:8080 -p 10241:50000 -v /usr/local/application/docker_vm:/var/jenkins_home -v /etc/localtime:/etc/localtime --name myjenkins jenkins/jenkins

-d 后台运行镜像
-p 10240:8080 将镜像的8080端口映射到服务器的10240端口。
-p 10241:50000 将镜像的50000端口映射到服务器的10241端口
-v /var/jenkins_mount:/var/jenkins_mount /var/jenkins_home目录为容器jenkins工作目录，我们将硬盘上的一个目录挂载到这个位置，方便后续更新镜像后继续使用原来的工作目录。这里我们设置的就是上面我们创建的 /var/jenkins_mount目录
-v /etc/localtime:/etc/localtime让容器使用和服务器同样的时间设置。
--name myjenkins 给容器起一个别名

3. 启动后查看日志

docker logs myjenkins

4. 配置镜像加速

cd /usr/local/application/docker_vm

修改hudson.model.UpdateCenter.xml里的内容:

vi  hudson.model.UpdateCenter.xml

将 url 修改为 清华大学官方镜像：https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

  
    default
    https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
  

5. 访问Jenkins页面，输入你的ip加上10240
