What are the best practices for pruning Docker images?

To effectively prune Docker images, consider the following best practices: 1. Regularly use docker image prune to remove unused images. 2. Use the -a flag to remove all unused images, not just dangling ones. 3. Schedule regular clean-up tasks to maintain a tidy environment. 4. Be cautious with production environments; ensure images are not in use before pruning.

How often should I run the prune command?

It depends on your usage, but running the prune command weekly or bi-weekly is a good practice for most environments. If you're frequently building and removing images, consider running it more often.

Can I automate the pruning process?

Yes, you can automate the pruning process using cron jobs or CI/CD pipelines to run the docker image prune command at scheduled intervals.

What happens if I prune an image that's still in use?

If you attempt to prune an image that is still in use by a container, Docker will not remove it. You will need to stop and remove the container first.
