Adding environment variables to config¶

We are going to modify the k8s/worker-deployment.yaml file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: worker-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      component: web
  template:
    metadata:
      labels:
        component: web
    spec:
      containers:
        - name: worker
          image: deiveris/multi-worker
          env:
            - name: REDIS_HOST
              value: redis-cluster-ip-service
            - name: REDIS_PORT
              value: 6379

And modify k8s/server-deployment.yaml:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: server-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      component: server
  template:
    metadata:
      labels:
        component: server
    spec:
      containers:
        - name: server
          image: deiveris/multi-server
          ports:
            - containerPort: 5000
          env:
            - name: REDIS_HOST
              value: redis-cluster-ip-service
            - name: REDIS_PORT
              value: 6379
            - name: PGUSER
              value: postgres
            - name: PGHOST
              value: postgres-cluster-ip-service
            - name: PGPORT
              value: 5432
            - name: PGDATABASE
              value: postgres
