Cleaning Pi with Docker Gladys V3 and V4

Presentations

Hello everyone!

I just noticed some slowness on my pi and watchtower that stops regularly.

I have a Raspbian desktop installed with my two instances of Gladys (V3 and V4) running under Docker.
I’m a bit lost on the areas to check to clean up.
A little help would be welcome to check all this…

pi@raspberrypi:/home $ df -h

/dev/root        15G   15G     0 100% /

tmpfs            93M     0   93M   0% /run/user/1000

Thanks in advance for future help.

I started with
docker system prune -a --volumes

It’s been running for 10 minutes… I’ll keep you posted after my coffee… :stuck_out_tongue:

Edit: long but good…
Total reclaimed space: 6.336GB

I will continue my cleaning process, I will put everything here for future cases.

That’s not a bad point, with watchtower running I wonder if it automatically cleans up old images or not! If not, everyone will quickly end up with a full SD card…

I’ll look into it

4

On my side, I had to extend my partition on the SD card as it was by default a few GB and was full after about 3 weeks of installation.
I also think the system is growing by leaps and bounds :wink:

It doesn’t clean, you should do that in a cron

6

I wonder if it wouldn’t be better to do this in Gladys (or in the Docker image), I would like to avoid adding code to the image as it cannot be updated later, whereas the Docker image is updated continuously.

7

Sure, why not, to be made optional (personally, I don’t want Gladys to manage that on my server)

We can document the cron for those who want the OS to be in control.

8

Or maybe a button in settings/system like the restart to clean?

9

The thing about the button is that if you don’t think about it, you’re in the same situation.

10

I’m trying something by thinking that maybe I’m right on a misunderstanding:

docker run -d \
    --name watchtower \
    -v /var/run/docker.sock:/var/run/docker.sock \
    containrrr/watchtower --cleanup

Couldn’t this launch method work?
See here: Arguments - Watchtower

If it’s cool, it’s an option they must have added, so problem solved for your rpi :grin:

Well spotted! :slight_smile: Perfect that
