Suggested Answer:

Step 1: Build a new application image by using dockerfile
Step 2: Create an alias if the image with the fully qualified path to the registry
Before you can push the image to a private registry, you've to ensure a proper image name. This can be achieved using the docker tag command. For demonstration purpose, we'll use Docker's hello world image, rename it and push it to ACR.
# pulls hello-world from the public docker hub
$ docker pull hello-world
# tag the image in order to be able to push it to a private registry
$ docker tag hello-word <REGISTRY_NAME>/hello-world
# push the image
$ docker push <REGISTRY_NAME>/hello-world
Step 3: Log in to the registry and push image
In order to push images to the newly created ACR instance, you need to login to ACR form the Docker CLI. Once logged in, you can push any existing docker image to your ACR instance.
Scenario:
Coho Winery plans to move the application to Azure and continue to support label creation.

LabelMaker app -
Azure Monitor Container Health must be used to monitor the performance of workloads that are deployed to Kubernetes environments and hosted on Azure
Kubernetes Service (AKS).
You must use Azure Container Registry to publish images that support the AKS deployment.

Correct answer given. Step 1: Build a new application image by using dockerfile FROM node:8.9.3-alpine RUN mkdir -p /usr/src/app COPY ./app/ /usr/src/app/ WORKDIR /usr/src/app RUN npm install CMD node /usr/src/app/index.js docker build ./aci-helloworld -t aci-test-app docker images docker run -d -p 8080:80 aci-test-app (Example to build image only and run locally) Step 2: Create an alias if the image with the fully qualified path to the registry docker tag mcr.microsoft.com/oss/nginx/nginx:1.15.5-alpine myregistry.azurecr.io/samples/nginx Step 3: Log in to the registry and push image docker push myregistry.azurecr.io/samples/nginx

You could still alias with a new build number, but yeah, not required. And, yes, the version can be a build number. But if only three can be chosen I will not select that

Strange question. I realize that from the provided options this is the only solution one can assemble. But the project describes LabelMaker app to be a set of images running in AKS. Pushing a new image into ACR won't change a thing, as one needs to update the YAML deployment file for Kubernetes to pick up the image, and then tell AKS to reconcile.

Question says "You need to deploy ...to ACR" - ACR is the registry - it does exactly that. Question does not say, that you need to update production containers.
