Lab 009: Working with Azure Container Registry

Requirements​

The Nautilus DevOps team has been tasked with setting up a containerized application. They need to create a Azure Container Registry (ACR) to store their Docker images. Once the repository is created, they will build a Docker image from a Dockerfile located on the azure-client host and push this image to the ACR repository. This process is essential for maintaining and deploying containerized applications in a streamlined manner.

  1. Create a ACR repository named devopsacr26050 under East US.

  2. Pricing plan must be Basic.

  3. Dockerfile already exists under /root/pyapp directory on azure-client host.

  4. Build a Docker image using this Dockerfile and push the same to the newly created ACR repo. The image tag must be latest i.e devopsacr26050:latest.

Note

The solution can be implemented using both the Azure Cloud Console and the Azure CLI. This document outlines the CLI-based approach to accomplish these tasks. It is recommended to first explore the Azure Cloud Console for hands-on experience and a practical understanding of the process before utilizing the CLI approach, unless specifically instructed otherwise.

Prerequisites​

  • Azure CLI and Docker are installed on the host.
  • You are authenticated with Azure CLI.
  • Dockerfile exists at /root/pyapp.

Steps​

ACR_NAME="devopsacr26050"
RESOURCE_GROUP=$(az group list --query "[?contains(name, 'kml')].name | [0]" --output tsv)
LOCATION="eastus"
SKU="Basic"
DOCKERFILE_PATH="/root/pyapp"
IMAGE_TAG="$ACR_NAME.azurecr.io/$ACR_NAME:latest"

az acr create \
  --resource-group "$RESOURCE_GROUP" \
  --name "$ACR_NAME" \
  --sku "$SKU" \
  --location "$LOCATION"

az acr login --name "$ACR_NAME"

docker build -t "$IMAGE_TAG" "$DOCKERFILE_PATH"
docker push "$IMAGE_TAG"

Verification​

  • Confirm ACR devopsacr26050 exists with SKU Basic.
  • Confirm image devopsacr26050:latest is present in ACR.
az acr show --resource-group "$RESOURCE_GROUP" --name "$ACR_NAME" --query "{name:name,sku:sku.name,location:location}" --output table
az acr repository list --name "$ACR_NAME" --output table
az acr repository show-tags --name "$ACR_NAME" --repository "$ACR_NAME" --output table
