AWN Term Project

Part1: Router

To start with Docker

Build images.

cd router/docker
docker network create my-routing
cd server
docker build -t server:latest .
cd ../router
docker build -t router:latest .

Run server.

docker run --rm --name server -p 8001:8001 --network my-routing server

Run router.

docker run --rm --name router -p 8201:8201 --network my-routing router

Run clients.

cd router/docker/client
python client_1.py
python client_2.py
python client_3.py

To start with Kubernetes

Build images.

cd router/kubernetes
cd server
docker build -t server:latest .
cd ../router
docker build -t router:latest .

Run server.

cd router/kubernetes
cd server
kubectl apply -f=server-deployment.yaml

Run router.

cd router/kubernetes
cd router
kubectl apply -f=router-deployment.yaml

You can list deployments and services by kubectl get deploy,svc

Run clients.

First, get the external IP of router by minikube service router

cd router/kubernetes
cd client

Edit the router IP in client_1.py, client_2.py, client_3.py before executing the following command.

python client_1.py
python client_2.py
python client_3.py

Part2: Proxy

To start with Docker

Build images.

cd proxy/docker
docker build -t proxy:latest .

Run proxy.

docker run --rm --name proxy -p 8080:8080 proxy

Now proxy service is at localhost, port8080.

To start with Kubernetes

Build images.

First, create repositories on dockerhub, ex: proxy.

docker login
//enter your dockerhub username and password
cd proxy/docker
docker build -t {dockerhubUserName}/{dockerhubRepoName}:latest .
docker push {dockerhubUserName}/{dockerhubRepoName}

Run proxy.

cd proxy/kubernetes
kubectl apply -f=proxy-deployment.yaml

You can list deployments and services by kubectl get deploy,svc

Apply Horizontal Pod Autoscaling on proxy.

cd proxy/kubernetes
kubectl apply -f=proxy-hpa.yaml

To check the autoscaler: list autoscalers by kubectl get hpa To stop the autoscaler: kubectl delete hpa/proxy

Apply Vertical Pod Autoscaling on proxy.

cd proxy/kubernetes
kubectl apply -f=proxy-vpa.yaml

To check the autoscaler: list autoscalers by kubectl get vpa get detailed description by kubectl describe vpa proxy To stop the autoscaler: kubectl delete vpa/proxy
