It only downloads it if it is not on local, we really only download an image once. We only bump the required image once every few months in launcher. There are ways to specify a base image BUT you do not want to do that for a rainbow of reasons.

Okay, so is there any way I can get rid of one of those images? I surely don’t need two base images?
How much disk space do you have?
Can you delete some backups?

Sure…
Have you ran ./launcher cleanup it will purge all images not in use.

Deleted them already.
Yes, I tried that. and I get
But when I try to rebuild or start the app, the base images that was presumably deleted by cleanup gets downloaded again and I’m back to where I started.
My suggestion here then if you are ULTRA tight on space is just to go nuclear and and start from scratch.
What is the output of docker ps, you basically need to kill your app container so you can free up the old base image.
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1fba0860cbc3 local_discourse/web_only "/sbin/boot" 5 months ago Up 29 minutes 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp web_only

2940a1603151 local_discourse/mail-receiver "/sbin/boot" 8 months ago Up 29 minutes 0.0.0.0:25->25/tcp mail-receiver
What do you mean by that? Will I need a discourse backup? Cause I don’t have one…
docker rm -f aa6b422d88ca
docker rm -f 1fba0860cbc3
./launcher cleanup
./launcher rebuild data
./launcher rebuild web_only
But really the root cause here is that you are just way too tight on disk space. I would recommend doubling the size /dev/mappper/vg-lv_root

Trying without the dropbox plugin now…
Hmmmm … are you on tests passed… stable or beta?
Also, remove discourse-sync-to-dropbox asap. It looks like it is not working at the moment.

Phew! After removing the dropbox plugin my site is finally back up and running. Thanks a lot to everyone for your support!
Since I never changed that, I guess I’m on tests-passed.
I guess you’re right, but how does that relate to discourse’s minimum requirements of 10 GB HDD?
10GB is ambitious and absolutely not the case if you are running seperate data and web containers.

Ah, I see. I don’t think that was mentioned anywhere. I’ll check tomorrow where that information might be usefully added.
However, the situation seems to look much brighter now:
$ df -h

Not sure where all the space came from but it looks good, doesn’t it? Do you still think I need to upgrade the server?
The data container was using the old image, so you had a situation where:
“data container” was saying HEY I need the old Discourse base image
“web container” was saying I need the new image
Not sure where all the space came from but this is a chunk of it.

How did that happen?
From my side, I can say that I started an update via /admin/upgrade which failed, presumably due to a lack of space. Since the website was down, I tried to rebuild via ssh and that’s when the whole misery started…
Regardless of this specific situation, I wonder if the web-updater could not handle lack of disk space better. Rather than crashing the site, could it not just exit before it’s too late?
Because you hadn’t upgraded the data container.
It could probably do a disk space check before it started, and refuse to proceed if there wasn’t enough space.

Another question:
Where did you get these IDs from:
Those are the container IDs (first column in the docker ps output).
