Docker Container开机自动启动
重启策略：使用在Docker run的时候使用--restart参数来设置。
no - container不重启
on-failure - container推出状态非0时重启
always - 始终重启

Restart Policies
Using the --restart flag on Docker run you can specify a restart policy for how a container should or should not be restarted on exit.
no - Do not restart the container when it exits.
on-failure - Restart the container only if it exits with a non zero exit status.
always - Always restart the container regardless of the exit status.
You can also specify the maximum amount of times Docker will try to restart the container when using theon-failure policy. The default is that Docker will try forever to restart the container.
$ sudo docker run --restart=always redis
This will run the redis container with a restart policy of always so that if the container exits, Docker will restart it.
$ sudo docker run --restart=on-failure:10 redis
This will run the redis container with a restart policy of on-failure and a maximum restart count of 10. If the redis container exits with a non-zero exit status more than 10 times in a row Docker will abort trying to restart the container. Providing a maximum restart limit is only valid for the on-failure policy.
