How can we optimize/clean disk usage from Docker and more?
-
I'm curious why the Umami app is so massive. It's such a lightweight application... is it expected to be that large? I wonder if this is somehow a contributor to the issue of reclaimable space but not actually being removed since it's still active? Just throwing against a wall though, not sure if that's valid. haha.

@girish That worked well for the volumes, it cleared up the 1.666GB of storage space. Thank you!
What about the images though? It says over 2 GB is reclaimable but it doesn't seem like it is from what I can tell. If I tried to do a similar command specific to images such as
docker image prune -ait still gave me a 0 byte response showing it cleaned up nothing. Am I missing something when it comes to reclaimable images in Docker? -

docker image prune -a it still gave me a 0 byte response showing it cleaned up nothing.
Just to say, I'm pretty sure that in the past I've done this and got a 0 byte response too, but then there actually was more space available.

FWIW, I uninstalled the app so that the image would be removed, confirmed it was removed, and then re-installed. The image size changed slightly from 6.57 GB to 6.51 GB, but still quite large. I may be doing in the wrong area though if we don't think this is a huge concern, just really strange to me why it's so much larger than all the other images when it's supposedly a fairly lean app.
For the life of me I cannot seem to reclaim the over 2 GB of disk space from images in Docker, I am puzzled as to why that is happening.

cleaning up the docker images as mentioned above basically works.
On my instance, there however are two app docker images that are much larger than the others:
rallly (almost 6GB), loomio (>6GB)
Is this size "normal"?
Is the "normal" size of the apps' docker images documented anywhere? -
@andreasb you can check the sizes of docker images here - https://hub.docker.com/u/cloudron . But looks like it lists only the compressed size. Size of docker images is not documented anywhere . The 6GB includes many layers and the layers are "shared" across apps (the way docker works).
We also hvae images on quay - https://quay.io/organization/cloudron . But I think this requires login, despite images being public . These sizes differ from dockerhub
