- What Grafana version and what operating system are you using?
I have a kubernetes deployment based on: grafana/grafana:9.0.2-ubuntu
- What are you trying to achieve?
Issues doing a new installation using a postgres database.
- How are you trying to achieve it?
I have defined the following variables:
GF_DATABASE_TYPE=postgres
GF_DATABASE_NAME=dashboard
GF_DATABASE_PASSWORD=FD38,eUGUhVX|iJ|0E<{cEIO ##staging so whatever you get an idea of the character set
GF_DATABASE_HOST=dashboard-v5-2-0-ha.postgres-operator.svc.cluster.local
GF_DATABASE_USER=dbadmin
- What happened?
Fails to start with the following error:
INFO [10-04|17:08:01] Path Plugins logger=settings path=/var/lib/grafana/plugins
INFO [10-04|17:08:01] Path Provisioning logger=settings path=/etc/grafana/provisioning
INFO [10-04|17:08:01] App mode production logger=settings
INFO [10-04|17:08:01] Connecting to DB logger=sqlstore dbtype=postgres
ERROR[10-04|17:08:01] alert migration failure: could not get migration log logger=migrator error="failed to check table existence: pq: no pg_hba.conf entry for host \"10.116.0.26\", user \"dbadmin\", database \"dashboard\", no encryption"
note, I additionally install a postgres-client. The following works without any problems:
psql -U $GF_DATABASE_USER -h $GF_DATABASE_HOST -d $GF_DATABASE_NAME
- What did you expect to happen?
A valid DB connection and a fresh grafana installation to succeed.
- Can you copy/paste the configuration(s) that you are having problems with?

- Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
UI won’t load.
- Final Notes
I tried setting GF_DATABASE_HOST to include the port number aka host:5432 and exclude it and it has the same behavior. Is there some special flag that needs to be passed in order to bootstrap the database ? Maybe something changed since the last time I went through this procedure with a fresh install.
Any help would be appreciated, but seeing as a valid DB connection can be established from the container to the database the issue shouldn’t be anything with kubernetes or services and something with the grafana configuration.
What am I missing?
