Testing out deploying simple go application in local kubernetes cluster with minikube

• make build - Build the go binary
• make docker-build - Build the docker image for the app
• make docker-push - Push docker image to docker hub (change the image name to push to your docker hub)
• make docker-run - Run the docker image

To run the app in kubernetes cluster use following commands

• First start local kubernetes cluster with minikube

minikube start

• Then create the configmap and secret

kubectl apply -f kube-go-secret.yaml
kubectl apply -f kube-go-config.yaml

• Then Start the deployment with

kubectl apply -f kube-go-deployment.yaml

This will run the app in kubernetes cluster with 2 replicas. In order to change it, modify kube-go-deployment.yaml and rerun the above command.

• To access the server from the browser start the service with

minikube service kube-go-service

minikube will automatically start your browser in the correct ip and port
