K8s-click-counter is a demo application, can be used for the Kubernetes workshops.
This demo app runs across two containers:
- backend - a Go REST API which serves the click's count.
- fronend - a simple Go web application calls the backend REST API /api/counter
- click-counter-backend
cd backend docker build -t click-counter-backend . docker run -it -p 9001:9001 click-counter-backend
- click-counter-frontend
cd frontend docker build -t click-counter-frontend . docker run -it -p 9000:9000 --env BACKEND_SERVICE=http://localhost:9001/api/counter click-counter-frontend
You can access the frontend on: http://localhost:9000
Deploy it on Kubernetes cluster:
kubectl apply -f https://raw.githubusercontent.com/C123R/k8s-click-counter/master/k8s-click-counter.yaml -n $(whoami) # it will create a namespace with your userid(whoami)
Since we are creating service as cluster type, we cant access it from outside our cluster. Still you can do it using kubectl port-forward.
kubectl port-forward service/click-counter-frontend-svc :80 -n $(whoami)
