As a follow-on to this post, for the "db" app to operate correctly in the Kubernetes environment variables need to be added to the "db" workload.

spec:
  containers:
  - env:
    - name: POSTGRES_HOST_AUTH_METHOD
      value: trust
    image: postgres:9.4
    imagePullPolicy: IfNotPresent
    name: postgres-1

This can be added by editing the deployment details in YAML.

    Another way to make the change is add the environment variable when creating the deployment. For me, this worked as the vote application recorded votes; my initial code above (based on this) did not have the expected result.

    The code generated by the dash board when establishing the environment instead looks like this:

    spec:
  containers:
  - env:
    - name: POSTGRES_HOST_AUTH_METHOD
      valueFrom:
        configMapKeyRef:
          key: POSTGRES_HOST_AUTH_METHOD
          name: db-config-dllr
    image: postgres:9.4
    imagePullPolicy: IfNotPresent
    name: postgres-1

    @cjmills thank you for updating this. Yes, db needs the environment variable as you described to either disable the auth ( enable trust) or to actually provide the password. I am updating the instructions as well as videos accordingly.
