How can I set up log rotation for my Docker containers?

You can set up log rotation for Docker containers by configuring the logging driver in your Docker daemon settings.

What logging drivers support log rotation?

The 'json-file' and 'local' logging drivers support log rotation. You can specify options like max-size and max-file.

Can you give me an example of how to configure this in the Docker daemon?

Sure! In your Docker daemon.json file, you can add:

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "3"
  }
}

This will limit log files to 10MB and keep a maximum of 3 files.

Do I need to restart Docker after making these changes?

Yes, you need to restart the Docker service for the changes to take effect.
