hello docker nginx!!!
14.刷新网页 即可
15.设置开机启动
[email protected]:/home/demo/html#systemctl enable docker
[email protected]:/home/demo/html#docker update --restart=always nginx--restart具体参数值详细信息：
no: 默认策略,容器退出时不重启容器；
on-failure: 在容器非正常退出时（退出状态非0）才重新启动容器；
on-failure:3 在容器非正常退出时重启容器，最多重启3次；
always: 无论退出状态是如何，都重启容器；
unless-stopped: 在容器退出时总是重启容器，
但是不考虑在 Docker 守护进程启动时就已经停止了的容器。
