## kube go

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

### Commands available

- `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

### Running the app in kubernetes with minikube

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
