Grafana (Docker) no longer starts, panics about alerts migration

Grafana Configuration

My Grafana instance (8.x) isn’t starting anymore, I think it panics on a rules migration. I’ve tried to set GF_FORCE_MIGRATION to true in the docker env variable but it doesn’t help:

grafana               | panic: New alert rules created while using unified alerting will be deleted, set force_migration=true in your grafana.ini and try again if this is okay.

grafana exited with code 2

Any idea what could be happening? I don’t care much about the alerts so I am fine removing them altogether

Solved by using docker cp to copy /usr/local/etc/grafana/grafana.ini locally, edit it then place it back and restart it.

Note that you can also use the environment variable:

GF_DEFAULT_FORCE_MIGRATION and set it to true like this:

GF_DEFAULT_FORCE_MIGRATION=true

Note the DEFAULT prefix as “force_migration” is inside the default section!
You can find that information here:
