Using minikube for k8s if you are using a virtual environment:

1. In a seperate terminal run minikube start
2. Under the webook directory, run make docker
   This will rebuild the webook-app binary and subsequently use it to build the docker image xjiang91/webook, version v0.0.1. Modify the image prefix in the Dockerfile if needed.
3. run docker tag $(docker images xjiang91/webook -q) xjiang91/webook:v0.0.1 && docker push xjiang91/webook:v0.0.1
   This will tage the image as xjiang91/webook:v0.0.1 and push to docker hub.
4. Run the following commands to start the k8s service:
   chmod 700 k8s.sh && ./k8s.sh

There are two ways to access the services:

1. To access a service (e.g.webook) via nodePort, run in terminal minikube service webook --url, and grab the address and go to the brower to visit it, e.g. http://192.168.76.2:32225/hello.
   Similary, you can access the mysql service by minikube service webook-mysql --url, and the redis service by minikube service webook-redis --url. You can then use the IP address and port to login.
2. If the service type is LoadBalancer, you can also open a tunnel to the minikube cluster by running in a seperate terminal: minikube tunnel and keep that terminal alive, then use kubectl get services to check the EXTERNAL-IP and port.
