What are the reasons for a Docker container automatically stopping?

There are several reasons why Docker containers automatically stop:

1. The application running inside the container encounters an error or crashes: When the application running within the container experiences an error or crashes, the container may automatically stop.
2. If there is insufficient memory or CPU resources within the container, the container may automatically stop running.
3. Tasks executed by containers are completed: some containers may be utilized for executing one-time tasks, and once the task is finished, the container will automatically stop.
4. The container’s start command has been executed: when this command is finished, the container may automatically stop. For example, if the start command is to run a script file, the container will stop once the script file has finished executing.
5. Abnormal Docker daemon: If the Docker daemon encounters any issues or stops running, all containers will automatically be stopped.
6. Containers can be manually stopped by using commands such as “docker stop” or by clicking the stop button in the Docker management interface.

One important thing to note is that containers automatically stopping does not result in the container being deleted; you can use the `docker start` command to restart the container.
