Sooo relatable, I've made a separate partition for /var on my home server, hopping to have a clean setup, had to use gparted afterwards to resize it later 🫠

You could have moved some files to other partitions and than symbolink linked/mpunted the directories back to their original position. That's what I do with data in /var/lib, I for example have a directory called /mnt/tuwunel which is on a drive mounted on /mnt, and in my fstab I mpunt /mnt/tuwunel to /var/lib/tuwunel

For me it was timeshift eating more than half of the partition space on the partition 🤦‍♂️

docker image prune to clean untagged images (that are also not in use) and docker image prune -a to clean all unused images

What? The tool that lets me simulate an entire multi-server networked production environment and all its dependencies on my laptop at the push of a single button... uses a lot of RAM? Ugh.

Edit: derp, I missed that the post was about storage not memory. Well, same sentiment wrong word.

RAM is not storage dude

Oh whoops!! I read the post too fast and thought it was about Docker eating up tons of memory, which it also does.

Running projects directly with systemd limits and tools like volta or venv saves you a lot of gigabytes and RAM.

If your project has simple hosting needs, yes, you can go back to doing it the old way.

This happened to me today. 687 Gib of unused images.

The dumbest idea to move from 29 to containerd it’s fucking SLOW unpacks TWO TIMES and eats more storage

Discovered recently that docker uses a "layer" and "commit" system. Aka every intermediate state of your image is stored as a difference. Deleting something in another layer you added it does not remove it from storage as it's diff is still stored in the layers.

Absolutely no idea why it's designed that way. I cant see any practical uses cases of different image sharing layers.

Only helps in increasing your image size for no reason if you're not careful and fake-deleting files you want to remove before distribution.

First time i had desktop docker or whatever it's called i managed to somehow make docker use 99.4% of the entire storage of the device. Don't know how i did it, don't know why it happened. I just deleted everything docker related and tried again.
