HOW TO USE INSIDE Kubernetes

Change ENV values inside deployment.yaml

    spec:
      containers:
      - env:
        - name: SIZE
          value: 3g
        - name: URL
          value: https://somesite.tobe.cached

Change domain inside ingress.yaml that serves cached content from bucket or any object storage defined in deployment.yaml
