#查看你需要安装的版本
docker search jenkins
#安装镜像包
docker pull jenkins/jenkins   #默认安装最新版本
#安装指定版本 指令入下
docker pull jenkins/jenkins:xx(版本号)
#查看是否安装成功(查看镜像包)
docker images

docker pull jenkins/jenkins:latest

#启动命令：

 #解释：
-d :后台运行
-p：10240：8080 镜像8080 ：端口映射到宿主机 10240端口
-p：10241：50000 镜像50000 ：端口映射到宿主机 10241端口
-v：/var/jenkins_home/workspace/:/var/jenkins_home/workspace/
/var/jenkins_home/workspace/ 宿主机的Jenkins目录挂载路径 jenkins
/var/jenkins_home/workspace/ 镜像服务器中jenkins的工作目录
-v /usr/bin/docker:/usr/bin/docker  : 挂载docker
-v /usr/local/java/jdk1.8.0_381:/usr/local/java : 挂载映射宿主机jdk
-v /usr/local/maven/apache-maven-3.9.3:/usr/local/maven : 挂载映射宿主机maven
-e JAVA_OPTS="-Dorg.apache.commons.jelly.tags.fmt.timeZone='Asia/Shanghai" \ ：同步时间
--name myjenkins（自定义容器名称） jenkins/jenkins（需要映射容器名称）
