Grafana not picking up environment parameters for image storage providers

I am using a docker compose file, root URL and domain are set by using environment parameters and are working.
- GF_USERS_ALLOW_SIGN_UP=false
- GF_SERVER_DOMAIN=grafana.example.com
- GF_SERVER_ROOT_URL=https://grafana.familie-mol.nl
- GF_external_image_storage.gcs_key_file=/var/lib/grafana/Grafana-c898b5187b1e.json
- GF_external_image_storage.gcs_bucket=Grafana

I have tried a lot of things like replacing the . With a _ also tried less tags.

Am I missing something, or is this a bug?

Hi,

Please refer to http://docs.grafana.org/installation/configuration/#using-environment-variables.

Everything should be upper case, . should be replaced by _

Then check your grafana server log for proper configuration.
