Hey everyone! I've noticed that Docker is occupying around 40 GB on my PC, even though I only have 4-5 GB of images stored. I had around 50 GB of free space before, but now I'm down to just 10 GB. The last time this happened, the virtual machine space was reduced automatically, but it hasn't happened this time. Any tips on how to reduce this space usage?

If you're using Docker Desktop on Windows, first clean up what you don't need inside Docker. Then, stop WSL (Windows Subsystem for Linux) and shrink the VHD (Virtual Hard Disk) that contains the Docker distributions. This can help reclaim some disk space. Check out some guides for specifics!
You can try running `docker system prune -af` to remove any unused images and reclaim space. If you're certain you have unused volumes too, you can add `--volumes` to that command. Just be cautious about what you're deleting, though!
Are there any methods to free up space without deleting images?
You might want to see what's reclaimable with the command `docker system df`. It shows you a summary of your disk usage, which can help you figure out what to clean up.
Is it safe to run this command regularly as a cron job?
