What should I do if my Docker container crashes?

What should I do if my Docker container crashes?

First, check the logs of the container using docker logs <container_id>. This will help identify the issue.

I checked the logs, and it says 'out of memory'. What can I do?

You can try increasing the memory limit for the container or optimizing the application to use less memory.

How do I increase the memory limit?

You can set the memory limit when you run the container using the -m flag, like this: docker run -m 512m <image_name>.

Is there a way to automatically restart the container if it crashes?

Yes, you can use the --restart flag when running the container. For example, --restart unless-stopped will restart it automatically.
