I don’t have any unused volumes, images etc. I did the setup for the entire Raspberry Pi4 8GB with 128 GB SD card just 12 hours ago.

You advice would be appreciated on how to stop that or limit its use or set a cleanup command. not sure to be frank.

I have another docker hosted on Synology NAS DSM and it doesn’t have this issue at all.

Good news! :love_you_gesture:

I found out the issue.

One of the containers was unhealthy and filling disk space with health logs and didn’t stop for days, hence, disk space was filled up.

Once the config was fixed on the container level, disk space is fine now.

I have the same problem on a pi 4. How did you fix the config? Thanks!
