need to connect remote database

[sohag033]

Hi,
I want to connect the remote database with PGSQL. I have already tried with just docker with below cmd and its working fine
docker run -d --name vaultwarden -e DATABASE_URL=postgresql://vaultwarden:password@db host:5432/vaultwarden -p 80:80 vaultwarden/server:latest

But in K8s I am trying to connect to the remote host with the below configmap. why it's not connected?

apiVersion: v1
kind: ConfigMap
metadata:
name: vaultwarden-configmap
namespace: sohag
data:
DATABASE_CONNECTION: "postgresql"
DATABASE_URL: "host.rds.com:5432"
POSTGRES_USER: "vaultwarden"
POSTGRES_PASSWORD: "Password"
POSTGRES_DB: "vaultwarden"

could you please help me to solve the problem?
BR,

So why don't you put the same:

DATABASE_URL: "postgresql://vaultwarden:password@db host:5432/vaultwarden"

in the configmap?
