Tasks

Step 1: Deploy Replication Controllers for Frontend and the Backend.

• Create Kubernetes Replication Controller and Pods for Frontend and Backend. Check this out to learn what replication controllers are.

• Make sure the pod count of Frontend and Backend is 1 if you’re running this locally. If you’re running this in production, pod count should atleast be 3.

• Make sure backend connects to PostgreSQL properly.

Step 2: Deploy Services.

• Create two services one for the frontend and one for the backend. Connect these services to Kubernetes RC’s.
• Services will expose a public IP address that you can then attach to your Domain’s DNS. (If you have a domain you already own, try this out. If you don’t have a domain. You can buy one or completely ignore this point.)

Step 3: Deploy Autoscaling Rules

• Set up Autoscaler for frontend and the backend.

Step 4: Test

• Test if the service is working properly.

Deliverable
