DB is not connected since we have not provide env variable for it.

env:
    - name: PORT
      value: "8080"
    - name: DB_USERNAME
      value: "chamod"
    - name: DB_HOST

kubectl create secret generic mongodb-secret -n prod -o yaml --dry-run=client > mongodb/mongodb-secret.yaml

Base 64 encode the DB_PASSWORD

echo -n "12345" | base64

Add that encoded password to our secret

data:
  db-password: MTIzNDU=

Ref secret to the env variable

- name: DB_PASSWORD
    valueFrom:
      secretKeyRef:
        name: mongodb-secret
        key: db-password
