I am stuck trying to debug a connection issue with PostgreSQL deployed with minikube. I've tried creating the postgres-service with both type NodePort and LoadBalancer but I cannot seem to connect with psql from my localhost.

I've copied in all the config (apologies), as I'm sure there's probably just a silly mistake somewhere!

apiVersion: v1
kind: Secret

  name: postgres-credentials
type: Opaque
data:
  user: YWRtaW4=
  password: YWRtaW4=
  database: YWRtaW4=

Trying to connect on my localhost:

$ kubectl get services
NAME               TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
kubernetes         ClusterIP   10.96.0.1       <none>        443/TCP          30h
postgres-service   NodePort    10.105.42.187   <none>        5432:32252/TCP   7m32s

$ export PGPASSWORD=admin
$ psql -h localhost -U admin -p 32252 admin
psql: could not connect to server: Connection refused

I've also tried creating a Ubuntu deployment in the cluster, using kubectl run -i --tty --attach --image=ubuntu -- bash, installing psql and connecting on 5432/32252, localhost/postgres-service, etc... but that doesn't work either.
