I’m trying to deploy an application with a NodePort Service on Kubernets cluster, but the deployment doesn’t work, and the pods are in a CrashLoopBackOff state with this logs:

panic: pq: password authentication failed for user “go”

goroutine 1 [running]:
main.main()
/server/main.go:15 +0x1f4

This is the manifest of the app :
apiVersion: apps/v1
kind: Deployment
metadata:
name: go-angular-app
spec:
replicas: 3
selector:
matchLabels:
app: go-angular-app
template:
metadata:
labels:
app: go-angular-app
spec:
containers:

• name: go-angular-app
  image: xxxxx
  ports:
• containerPort: 8080
  env:
• name: POSTGRES_USER
  value: “go”
• name: POSTGRES_PASSWORD
  value: “root”
• name: POSTGRES_DB
  value: “go”
• name: POSTGRES_HOST
  value: “students-db-svc”

And this is the manifest of the service of the app :
apiVersion: v1
kind: Service
metadata:
name: go-angular-service
spec:
type: NodePort
selector:
app: go-angular-app
ports:

• protocol: TCP
  port: 80
  targetPort: 8080
  nodePort: 30081

And this is the manifest of the Postgress deployment:
apiVersion: apps/v1
kind: Deployment
metadata:
name: students-db
spec:
replicas: 1
selector:
matchLabels:
app: students-db
template:
metadata:
labels:
app: students-db
spec:
containers:

• name: postgres
  image: postgres:11.5
  ports:
• containerPort: 5432
  env:
• name: POSTGRES_USER
  value: “go”
• name: POSTGRES_PASSWORD
  value: “root”
  name: POSTGRES_DB
  value: “go”

and this is the db service manifest :
apiVersion: v1
kind: Service
metadata:
name: students-db-svc
spec:
selector:
app: students-db
ports:

• protocol: TCP
  port: 5432
  targetPort: 5432

I tried changing the environment variables and nothing has changed the pods are always on that state and they are supposed to be in RUNNING state What to do ? and thank you.
