I am new to kubernetes and trying to install eclipse che on minikube. It requires postgres and keycloak pods. but sadly keycloak pod crashloops because of

Caused by: org.postgresql.util.PSQLException: FATAL: password authentication failed for user "keycloak"

What I tried

I explicitly created password for keycloak user on postgres DB, but no luck.

OS: centos7 VM

cluster: minikube single node cluster (v.1.22.0)

postgres pod and database are up and running

keycloak image: quay.io/eclipse/che-keycloak:7.35.1

minikube cluster pod details:

Error log:

error log from keycloak pod:
