Kubernetes example

The deployment.yml. The infrastructure bit creation is up to the platform being used (e.g. AWS EKS):

apiVersion: apps/v1
kind: Deployment
metadata:
  name: microgram-auth
spec:
  replicas: 1
  selector:
    matchLabels:
      app: microgram-auth
  template:
    metadata:
      labels:
        app: microgram-auth
    spec:
      containers:
        - name: microgram-auth-app
          image: <remote>/microgram-auth:latest
          imagePullPolicy: Always
          env:
          - name: POSTGRES_USERNAME
            value: <change>
          - name: POSTGRES_PASSWORD
            value: <change>
          - name: POSTGRES_HOST
            value: <change>
          - name: POSTGRES_DB
            value: <change>
          - name: JWT_SECRET
            value: <change>
          - name: CORS_ORIGIN
            value: <change>
          ports:
            - name: web
              containerPort: 5000
              protocol: TCP

The service.yml with a simple load balancer. The infrastructure bit creation is up to the platform being used (e.g. AWS ELB).

apiVersion: v1
kind: Service
metadata:
  name: microgram-auth-lb-svc
spec:
  selector:
    app: microgram-auth
  type: LoadBalancer
  ports:
    - name: http
      protocol: TCP
      port: 80
      targetPort: web

Apply both to the Kubernetes cluster:

kubectl apply -f deployment.yml
kubectl apply -f load_balancer.yml

› kubectl get pods
