Cleanup Docker to save disk space

AdamM

Hi
I have noticed that my server with Enhance keeps having a problem with increasing disk usage size.
I did some investigation and found that docker leaves a lot of files behind
Example if you upgraded Enhance from version 8.1.0 to 8.2.0 the docker files still remain on the server
it can be cleaned

be careful, it may remove docker images that are disabled
Make sure Enhance and all docker images are running,

docker ps -a

if you are sure that everything is working properly you can clear the old files in docker
you can also back up your server beforehand

sudo docker system prune -a

this command cleared almost 5gb of old data for me

Please be careful with this command. If any containers are stopped then this command will delete them. Check for stopped containers first!

Or run "docker image prune" instead which will just clean up unused images.

AdamM

Yes, be careful with stopped images. I am not responsible for damages 🤭

AdamM Thanks a lot for sharing all this. It really helps.

If I've understood well we can just type the command Adam suggested:

docker image prune

instead of docker system prune -a

Adrien
when I used

docker image prune

nothing has been removed

does "docker image prune -a" cleans-up php versions not in use?

No but that feature is coming.
