I'm trying to install keycloak on GKE cluster in GCP with external database, i.e. CloudSQL postrges db. I want to use helm to install it, so:
helm repo add bitnami https://charts.bitnami.com/bitnami
I've downloaded Values.yml file from bitnami repo, and I've updated "externalDatabase.externalSecret" section of this file, since I don't want to enter credentials in plain text. Instead I've created Kubernetes Secret:
$ kubectl get secret keycloak-db-secret -o yaml
apiVersion: v1
data:
POSTGRES_DATABASE: <value>
POSTGRES_EXTERNAL_ADDRESS: <value>
POSTGRES_EXTERNAL_PORT: <value>
POSTGRES_PASSWORD: <value>
POSTGRES_USERNAME: <value>
kind: Secret
metadata:
...
And modifications in Values.yml are (the rest of the file is not changed):
postgresql:
enabled: false
externalDatabase:
existingSecret:
name: keycloak-db-secret
keyMapping:
host: POSTGRES_EXTERNAL_ADDRESS
port: POSTGRES_EXTERNAL_PORT
user: POSTGRES_USERNAME
password: POSTGRES_PASSWORD
database: POSTGRES_DATABASE
When I run
helm install --debug my-keycloak bitnami/keycloak -f Values.yml
I get an error message
install.go:173: [debug] Original chart version: ""
install.go:190: [debug] CHART PATH: /home/michal/.cache/helm/repository/keycloak-5.0.7.tgz

I've checked the templates/statefulset.yaml but couldn't find anything which could be a problem (I'm the helm beginner). The line 88 refers to generated yaml file and not the template file which makes the bug hunting harder.
What am I missing in my configuration? How can I debug it further? please help
PS. The documentation for connecting Keycloak to external database is here :( https://docs.bitnami.com/kubernetes/apps/keycloak/configuration/use-external-database/
