External postgres database unreachable from kubernetes pods.

[NagenderSinghRathore]

I have been trying to deploy Defectdojo on Kubernetes(AWS EKS) with RDS postgresql as database using helm.

Document referred: https://github.com/DefectDojo/django-DefectDojo/blob/master/readme-docs/KUBERNETES.md

Steps followed:

1. Postgresql secret creation:

kubectl -n defectdojo create secret generic defectdojo-postgresql-specific --from-literal=postgresql-password=<rds-password> --from-literal=postgresql-postgres-password=<rds-password>

2. Helm chart installation:

helm install defectdojo ./helm/defectdojo --namespace="defectdojo" --set django.ingress.enabled=false --set django.ingress.activateTLS=false --set createSecret=true --set createRabbitMqSecret=true --set createRedisSecret=true --set createMysqlSecret=false --set createPostgresqlSecret=false --set mysql.enabled=false --set postgresql.enabled=false --set postgresql.postgresServer="jdbc:postgresql://<rds-endpoint>:5432"

Now, I am getting below errors in the celery and django pods:
django.db.utils.OperationalError: could not translate host name "jdbc:postgresql://<rds-endpoint>:5432" to address: Name or service not known.

I spun up another pod in the same namespace and able to telnet to the rds-endpoint.

What am I missing here?

Would be really grateful for any help on this.
