Postgres config¶

We are going to create a deployment for redis k8s/postgres-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgres-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      component: postgres
  template:
    metadata:
      labels:
        component: postgres
    spec:
      containers:
        - name: postgres
          image: postgres
          ports:
            - containerPort: 5432

And the ClusterIP at k8s/postgres-cluster-ip-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: postgres-cluster-ip-service
spec:
  type: ClusterIP
  selector:
      component: postgres
  ports:
    - port: 5432
      targetPort: 5432

And now apply:

$ kubectl apply -f k8s
service/client-cluster-ip-service unchanged
deployment.apps/client-deployment unchanged
service/postgres-cluster-ip-service created
deployment.apps/postgres-deployment created
service/redis-cluster-ip-service unchanged
deployment.apps/redis-deployment unchanged
service/server-cluster-ip-service unchanged
deployment.apps/server-deployment unchanged
deployment.apps/worker-deployment unchanged
