Nginx – Using Superset helm chart with pre-existing postgres database

I have a k8s cluster which I have already installed Apache Superset with Postgres dependency enabled. But now I want to use my own PostgresDB so I configured values.yaml

postgresql:
  ## Set to false if bringing your own PostgreSQL.
  enabled: false

# ...

supersetNode:
  connections:
    db_host: "10.0.0.0"
    db_port: "5432"
    db_user: my-db-user
    db_pass: "secret"
    db_name: superset

I have already tested connecting with psql from inside pod in cluster and it works.

But when I run install command:

 helm install superset ../mypath/superset/ -n superset 
    --wait --timeout=15m0s 
    --namespace superset --create-namespace 
    -f ../mypath/superset/values.yaml 

It just never deploys successfully, I keep getting error:

superset connection to server at "10.0.0.0", 
port 5432 failed: FATAL:  password authentication failed for user "my-db-user"

I then tried attaching debugger image to superset pod:

kubectl debug -n superset superset-657c7b68d6-x257b -it --image=arunvelsriram/utils

And then run psql -U my-db-user -h 10.0.0.0 -d superset -p 5432 and it works so it’s not a networking issue

I’m in GKE in case that makes any difference and am using a pre-existing Nginx load balancer Ingress.
