Based on "standard" ONAP installation used for Daily pipelines.

Based on:
https://github.com/codecentric/helm-charts/blob/master/charts/keycloakx/examples/postgresql/readme.md

Add helm registries:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo add codecentric https://codecentric.github.io/helm-charts
helm repo update

Create value files for PostgreSQL instance (storageClass only required, if default class is not defined):

keycloak-db-values.yaml

# See https://github.com/bitnami/charts/tree/master/bitnami/postgresql
global:
  postgresql:
    auth:
      username: dbusername
      password: dbpassword
      database: keycloak
  storageClass: cinder-csi

Create value file for keycloak server:

# This is an example configuration, for production grade configuration see the Keycloak documentation.
# See https://www.keycloak.org/server/configuration
# See https://www.keycloak.org/server/all-config
command:
  - "/opt/keycloak/bin/kc.sh"
