I just have to point out that this warning message is very scary if one does not deeply understand how discourse works. At the very least, there should be a message above that basically mentions to what This refers so you know that it’s (probably) ok to continue!
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all images without at least one container associated to them
- all build cache
Are you sure you want to continue? [y/N] y
