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]

@d19dotca for volumes, thee was a bug. I fixed this in master yesterday - https://git.cloudron.io/cloudron/box/-/commit/030e4688294d0ffe1c34468e6622c4b1b22fd357

[girish]

@d19dotca speak of the devil... there is a new version of umami, let me check why it's so big.

@d19dotca said in How can we optimize/clean disk usage from Docker and more?:

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.

Just the node modules is 1.4G

@girish does that mean the image should only be about 1.4 GB in size rather than the 6+GB I’m seeing currently? Very odd if that’s the case, I wonder how that exploded in size.

[d19dotca]

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.

[girish]

@d19dotca it seems the yarn cache was note cleared. Clearing it brought down the size . It's in the new package.

[andreasb]

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?

[joseph]

@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
