You'll need to install docker https://docs.docker.com/install/. Open a new terminal within the project directory and run:

1. Build the images: docker-compose -f course-03/exercises/udacity-c3-deployment/docker-compose-build.yaml build --parallel
2. Push the images: docker-compose -f course-03/exercises/udacity-c3-deployment/docker-compose-build.yaml push
3. Run the container: docker-compose -f course-03/exercises/udacity-c3-deployment/docker-compose-build.yaml up

2.1 Install eksctl from here
2.2 Create configmap env-config and secret env-secret and aws-secret.
There are many environment variables are referenced from inside *-deployment.yaml files. You must create env-config configmap and env-secret secret for your kubectl. Please follow the official instructions on how to create configmap and how to create secret. For quick start, See here for how to prepare secret yaml file.

kubectl create configmap env-config --from-env-file=/path/to/.env.list
kubectl apply -f /path/to/env-secret.yaml
kubectl apply -f /path/to/aws-secret.yaml

Note that each row in .env.list is a key=value pair.

2.2 Run the helper script
$> course-03/exercises/udacity-c3-deployment/k8s/create_cluster.sh

3.1 Prerequisite: install kubectl from here
3.2 Deployment backend,frontend and reverseproxy services

cd course-03/exercises/udacity-c3-deployment/k8s
kubectl -f apply backend-feed-deployment.yaml
kubectl -f apply backend-user-deployment.yaml
kubectl -f apply frontend-deployment.yaml
kubectl -f apply reverseproxy-deployment.yaml

3.3 Deploy services for the above deployments

kubectl -f apply backend-feed-service.yaml
kubectl -f apply backend-user-service.yaml
kubectl -f apply frontend-service.yaml
kubectl -f apply reverseproxy-deployment.yaml

or simply run deploy_to_cluster.sh script in folder course-03/exercises/udacity-c3-deployment/k8s
Without deploy the services, the reverseproxy cannot resolve the hostname backend-user and backend-feed in the nginx.conf file

3.4 port-forward

k port-forward service/frontend 8100 8100
k port-forward service/reverseproxy 8080 8080
