Example: kubernetes deployment environment variables

metadata:
  name: envar-demo
spec:
  replicas: 1
  template:
	spec:
      containers:
      - name: envar-demo-container
        image: gcr.io/google-samples/node-hello:1.0
        env:
        - name: DEMO_GREETING
          value: "Hello from the environment"
        - name: DEMO_FAREWELL
          value: "Such a sweet sorrow"
