This is a simple web server that increments visits counter and can be scaled horisontaly. Application is written in Go and uses Redis as backend. Image is available on Docker hub:
docker pull zokoko/allthingstalkgo
It can be easily run on Google cloud using provided Kubernetes configuration files.
Assuming there is a valid project and billing setup, first step is to create container cluster:
gcloud container clusters create attgo-cluster --num-nodes=3
Next is to setup and expose Redis backend:
kubectl create -f kubectl\redis-master.yaml
kubectl create -f kubectl\redis-master-service.yaml
And finaly we deploy the Docker container with app:
kubectl run attgo --image=zokoko/allthingstalkgo --port=8080
kubectl expose deployment attgo --type="LoadBalancer"
kubectl scale deployment/attgo --replicas=4
After the external IP is assigned to the attgo service, application can be opened on path /att
