I launched a pod in rancher with docker.io/bitnami/postgresql:11.6.0-debian-10-r0. The pod can be successfully started and the postgres daemon is started. However, inside the pod, I got a "I have no name" shell prompt.
The pod log did say creating password for postgres user. However, I don't have root password, neither do I have sudo, or su to postgres. The pgsql db is running but cannot be accessed from pgadmin outside the pod.
