Kubernetes Multicontainer

First, we need to create our own images of the sample application.

  1. Build images local. Navigate to the apps folder and into the js-calc-frontend folder. Then run:
docker build -t calcfrontend .

Do the same for the backend (folder: apps/js-calc-backend).

  1. Push the images to your ACR.

    • Login to your ACR
    docker login <YOURREGISTRY>.azurecr.io

    Provide username and password as found in the portal.

    • Tag your image
    docker tag calcfrontend <YOURREGISTRY>.azurecr.io/calcfrontend
    • Then push your images. Do it for both frontend and backend images.
    docker push <YOURREGISTRY>.azurecr.io/calcfrontend

    Your images are now available in your ACR.

  2. Run your images by using YAML files (you can find sample files under hints/yaml folder). Make sure, you adjust the files with your own container registry/tags of the images. You will need to deploy your pods for the backend + a backend service and the frontend pods + a frontend service. E.g.:

kubectl apply -f backend-pod.yml
kubectl apply -f backend-svc.yml
kubectl apply -f frontend-pod.yml
kubectl apply -f frontend-svc.yml

Have a look at the frontend-svc.yml file (type: LoadBalancer! You will receive a public IP adress that exposes your frontend service to the public internet via the Azure load balancer!).
