How docker restarts the container
This article introduces docker how to restart the container, the content is very detailed, interested friends can use for reference, I hope it can be helpful to you.
The restart strategy of the docker container is a startup strategy for the production environment, which can be ignored in the development process. The restart of the Docker container is done by the Docker daemon, so it is closely related to the daemon.
The restart strategy for the Docker container is as follows:
No, the default policy, does not restart the container when it exits
On-failure, the container will be restarted only when the container exits abnormally (the exit status is not 0)
On-failure:3, restart the container when it exits abnormally, up to 3 times
Always, always restart the container when it exits
Unless-stopped, which always restarts the container when it exits, but does not consider containers that have been stopped when the Docker daemon starts

-restart option for docker run
With the-restart option, you can set the container restart policy to determine whether the Docker daemon restarts the container that just exited when the container exits.
The-restart option is usually used only for containers in detached mode.
The-restart option cannot be used with the-rm option. Obviously, the-restart option applies to containers in detached mode, while the-rm option applies to containers in foreground mode.
When docker ps looks at containers, the only possible states for containers that use the-restart option are Up or Restarting.
So much for sharing about how docker restarts the container. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
