在本地查看镜像

在这里插入图片描述

运行镜像，发现并没有正确运行 jenkins

排查问题

在镜像介绍的文档中，有一个连接，点进去看看。

在这里插入图片描述
发现是一个 github 地址

https://github.com/jenkinsci/docker/blob/master/README.md

通过阅读文档发现，原来 jenkisn 运行需要一个 jdk11 的镜像，并且给出了jdk 镜像下载办法。

docker run -p 8080:8080 -p 50000:50000 --restart=on-failure jenkins/jenkins:lts-jdk11

意思是：运行jenkins:lts-jdk11 镜像时，宿主的端口 8080 映射到虚拟机的 50000 端口，在 docker 只有在非0状态退出时才重新启动容器；
在这里插入图片描述
运行结果：

zhao@sh-zhao ~ % docker run -p 8080:8080 -p 50000:50000 --restart=on-failure jenkins/jenkins:lts-jdk11
