I use grafana as part of my home assistant docker install. Yesterday I have upgraded debian buster to debian bullseye. Exact the same config has worked fine before.

The data files are stored as user 1000 (dietpi) and the user can create files in tmp.

dietpi in DietPi in ~ ✦ ❯ id
uid=1000(dietpi) gid=1000(dietpi) Gruppen=1000(dietpi),4(adm),5(tty),20(dialout),24(cdrom),27(sudo),29(audio),33(www-data),44(video),46(plugdev),60(games),100(users),101(input),108(netdev),121(render),997(gpio),998(i2c),999(spi)
dietpi in DietPi in ~ ✦ ❯ touch /tmp/4947
dietpi in DietPi in ~ ✦ ❯

I just don’t understand were the error comes from. What is meant, the /tpm of the host or /tmp inside the container?
Can someone point me to the right direction.
TIA Micha

The problem is that inside the container not a writable tmp dir is.
Now I have set

  • TMPDIR=/var/lib/grafana/tmp
    in docker compose file. Now it works
