Obtain the database port in a dynamic fashion.

At the moment the redis database's port is edited into the services.yaml file using a sed script and some kubectl get stuff.

What I want to do is to simply reference the dynamically created port number.

See here for ideas

This moodle reference shows how to obtain the port from the database secret:

I need more than the port, I need the hostname. This article showed me how I can use the $() construct to concatenate strings. I think the following might work:

          - name: REDIS_PORT
            valueFrom:
              secretKeyRef:
                name: redis-enterprise-database
                key: port
          - name: REDIS_HOST
            valueFrom:
              secretKeyRef:
                name: redis-enterprise-database
                key: service_name              
          - name: REDIS_ADDR
            value: "$(REDIS_HOST):$(REDIS_PORT)"
