Task 1: Launching K8s and deploy our containers

Launch your Kubernetes cluster

1. Start the Kubernetes cluster

minikube start

2. Get the instructions to point your docker client to point to the minikube docker daemon

minikube docker-env

3. Check the status of your minikube deployment

minikube status

Deploy the containers into the cluster

1. Enter the k8s folder and input the following command:

kubectl apply -f deployment.yaml
kubectl apply -f service.yaml

2. Check the status of your deployment

kubectl get pods
kubectl get deployment
kubectl get services

3. Answer the following questions and include the answers in your report:

• What is Kubernetes? Why do we need it? (5 points)
• Please explain the concepts of Deployment, Service and Pod. (5 points)
• Why k8s use pod to manipulate the application instead of the container. (5 points)
• What is Replica Set in Kubernetes? (5 points)
• Why can the client successfully communicate through port 30080 when the server is listening on port 8888? (10 points)

(Optional) Check if your container is running correctly on the minikube

1. Get the ip address of the minikube:

minikube ip

2. Enter the client folder, open and modify the PLEASE ASSIGN section in socket_client.c. (Replace with your actual student ID):

3. Tear down the deployed services and minikube cluster after you finished testing:

kubectl delete -f service.yaml
kubectl delete -f deployment.yaml
minikube stop
