Figure out which container is consuming all available disk space

[humphd]

From @manekenpix on Slack:

so, something is eating up our disk space on staging, but I'm not sure what it is, but I know that if I stop telescope and relaunch it, we get a big chunk of disk space back. I don't think it's related to dangling images or volumes since we haven't merged anything in a while. Telescope had been running for 36 hours straight, and I had to shut it down and back up to get some disk space back. I'll file an issue when I have more info
from what I can see, it's a container that stores something in itself (probably not using a volume) and it gets deleted when the container is destroyed (shut down telescope). This also happens on production, but we have a lot more free disk space on production, so it's not an issue (on staging, we get to 95% disk usage in less than 2 days)

I did a quick scan through the containers on Portainer, and I can't figure it out. For example, going to https://dev.portainer.telescope.cdot.systems/#!/1/docker/containers/b01f331167b374581f7c56b2cf7ae17a47d8887d6bbbbda6c891fb803ff98687/stats shows the CPU, Memory, Network and I/O usage for the rss-bridge service. Each container can show you the same.

None of the ones I looked at showed any significant disk I/O.

Running everything locally, I see:

If you scroll that all the way to the right, you can see the total size of the containers. Notice:

• supabase-db is 2.31GB
• elasticsearch is 437MB

Everything else is tiny. I'll let this run for a while and see what it does. It would be interesting to see this same data for staging/prod.
