May not be an answer for Minikube, but I ended up here so I share what I did for Kubernetes in Docker for Mac.

I added a service like this for PostgreSQL:

kind: Service
apiVersion: v1
metadata:
  name: postgres
  namespace: default
spec:
  type: ExternalName
  # https://docs.docker.com/docker-for-mac/networking/#use-cases-and-workarounds
  externalName: host.docker.internal
  ports:
    - name: port
      port: 5432

My application was able to connect to the locally running postgres server with this setup using the domain name postgres. The Postgres server can listen to 127.0.0.1 with this setup.
