Ports must be named (GITA-PRO-007)

Kubernetes allows container ports to have identifiers on the Pod level. These identifiers can later be used to reference the port through the Service field targetPort. This ensures port references won't have to be changed in case the program starts using a different port, be it due to internal changes to the program or changes to the network where it executes.

A port name can be specified through the name sub-field within the ports section of a manifest as follows:

apiVersion: v1
kind: Pod
metadata:
  name: redis
spec:
  containers:
    - name: redis
      image: redis:latest
      ports:
        - containerPort: 6379
          name: redis-port
