部署 Jenkins 服务器
一、部署 Jenkins 容器（赋予 Docker 访问权限）
通过 Docker 运行 Jenkins 容器，同时挂载宿主机的 Docker 相关文件（让 Jenkins 能操作宿主机 Docker）、持久化 Jenkins 数据：
[root@host1 ~]# docker run --restart always -u root --privileged -d
-p 8999:8080
-p 50000:50000
-v /var/jenkins_home:/var/jenkins_home
-v /var/run/docker.sock:/var/run/docker.sock
-v /usr/bin/docker:/usr/bin/docker
-v /etc/docker:/etc/docker
--name jenkins

--restart always：容器随 Docker 自动重启。 -
-u root --privileged：赋予容器 root 权限，确保能操作宿主机 Docker。 -
-p 8999:8080：Jenkins Web 界面映射到宿主机8999端口。
