I'm trying to connect a Postgres pod with my Django app pod but somehow my Django app pod port is not exposed. In my app's Dockerfile I added EXPOSE 8000, however when I ssh into my pod I cannot serve my app (returns an error asking if a postgres server is up and running on port 5432 and accepting TCP/IP connections on port 5432) and when run nmap I get this

root@app-kbqd8:~/app# nmap 12.3.4.567

Starting Nmap 7.01 ( https://nmap.org ) at 2017-01-06 15:24 UTC
Nmap scan report for postgres-service.default.svc.cluster.local (12.3.4.567)
Host is up (0.00063s latency).
All 1000 scanned ports on postgres-service.default.svc.cluster.local (10.0.0.171) are filtered

My app's service is:

---
kind: Service
apiVersion: v1
metadata:
  name: app-service
spec:
  selector:
    name: myapp
  ports:
    - port: 80
      targetPort: 8000
      protocol: TCP

For my postgres pod

---
kind: Deployment
apiVersion: extensions/v1beta1
containers:
    - name: postgres
      image: user/postgres
      imagePullPolicy: IfNotPresent
      ports:
        - containerPort: 5432

and its service

---

apiVersion: v1

spec:

    - port: 5432
      targetPort: 5432
