dependency-track is unable to connect to bitnami postgresql on Kubernetes

I have deployed Bitnami PostgreSQL (chart: 16.7.10, app: 17.5.0) on my AWS EKS Kubernetes cluster under the namespace appdev-dependency-track along with Dependency-Track (chart: 0.34.0, app: 4.13.2).

Problem is, API Server pod of Dependency-Track is unable to connect to PostgreSQL.

Upon changing the URL, I either get the following error, Caused by: java.net.UnknownHostException: postgresql-postgresql, or the pod gets restarted after printing the following log lines without printing and error with exit code 143:

I'm stuck.

Answer

After changing:

• ALPINE_DATABASE_URL to jdbc:postgresql://postgresql.appdev-dependency-track.svc.cluster.local:5432/postgres

• Increasing initialDelaySeconds to 120 in the livenessProbe

It worked.

My API servers configuration for Dependency-Track to connect with Bitnami PostgreSQL is as follows:

apiServer:
  extraEnv:
    - name: SYSTEM_REQUIREMENT_CHECK_ENABLED
      value: "false"
    - name: ALPINE_DATABASE_MODE
      value: "external"
    - name: ALPINE_DATABASE_URL
      value: "jdbc:postgresql://postgresql.appdev-dependency-track.svc.cluster.local:5432/postgres"
    - name: ALPINE_DATABASE_DRIVER
      value: "org.postgresql.Driver"
    - name: "ALPINE_DATABASE_USERNAME"
      value: "postgres"
    - name: "ALPINE_DATABASE_PASSWORD"
      valueFrom:
        secretKeyRef:
          key: postgres-password
          name: postgresql
