Orchestrating Docker with Kubernetes

This is a demo app to showcase orchestrating Docker with Kubernetes. You can find more at my post.

Usage

1. Run backend

kubectl create -f backend.yaml

2. Run frontend

kubectl create -f frontend.yaml

3. Self-healing

Delete a random pod and see Kubernetes creates a new one.

kubectl delete pod frontend-2747139405-bk4ul; kubectl get pods

4. Scaling

kubectl scale deployment/frontend --replicas=6; kubectl get pods

5. Rolling update

kubectl create -f frontend-canary.yaml
vim frontend.yaml # update simple-node:v1 to simple-node:v2
kubectl apply -f frontend.yaml
