Prometheus bad permissions when using volume driver

clayrisser opened this issue · comments

The Prometheus service breaks when using a custom docker volume driver. Basically, the container does not have permission to write to the /prometheus folder. This is because root permission is needed to write to that folder when using a volume driver (specifically rancher-nfs in my case). The default user for the Prometheus container is nobody, hence the write permission error.

I too have the same issue - Have tried both rancher-nfs and local volume-drivers

The solution is to set user to root. You can see how I did it in my docker-compose.yml file.

prometheus:
  image: prom/prometheus:v2.1.0
  user: root
# etc . . .

My pull request at the link below fixes it. Hopefully, they accept it soon.
