ACR image building and pushing in Azure - Mini Project: Build & Apply

ACR image building and pushing

📖 Scenario: You work as a cloud engineer for a company that uses Azure Container Registry (ACR) to store Docker container images. Your team wants to automate the process of building a Docker image from source code and pushing it to ACR for deployment.

🎯 Goal: Build a Docker image from a simple Dockerfile and push it to an Azure Container Registry repository using Azure CLI commands.

📋 What You'll Learn

Create a variable for the Azure Container Registry name

Create a variable for the Docker image name and tag

Use Azure CLI to build the Docker image with az acr build

Verify the built image in the Azure Container Registry

💡 Why This Matters

🌍 Real World

Automating container image builds and pushes to Azure Container Registry is common in DevOps pipelines for cloud applications.

💼 Career

Cloud engineers and DevOps professionals use these skills to manage containerized applications and streamline deployments.

1

Set the Azure Container Registry name

Create a variable called acr_name and set it to the exact string mycontainerregistry which is the name of your Azure Container Registry.

Azure

# Create a variable called acr_name and set it to 'mycontainerregistry'
# Your code here

Need a hint?

The Azure Container Registry name is a unique string identifying your registry. Use the exact name mycontainerregistry.

2

Set the Docker image name and tag

Create a variable called image_name and set it to the exact string myapp:v1 which represents the Docker image name and tag.

Azure

acr_name = 'mycontainerregistry'
# Create a variable called image_name and set it to 'myapp:v1'
# Your code here

Need a hint?

The Docker image name includes the tag after a colon. Use myapp:v1 exactly.

3

Build the Docker image using Azure CLI

Write a command string called build_command that uses az acr build to build the Docker image. Use the variables acr_name and image_name in the command. The command should build from the current directory ..

Azure

acr_name = 'mycontainerregistry'
image_name = 'myapp:v1'
# Create a variable build_command with az acr build command using acr_name and image_name
# Your code here

Need a hint?

Use an f-string to insert acr_name and image_name into the az acr build command. The build context is the current directory ..

4

Verify the Docker image in Azure Container Registry

Write a command string called push_command that uses az acr repository show to confirm the image exists in the registry. Use acr_name and image_name variables in the command.

Azure

acr_name = 'mycontainerregistry'
image_name = 'myapp:v1'
build_command = f"az acr build --registry {acr_name} --image {image_name} ."
# Create a variable push_command to check the image in ACR using az acr repository show
# Your code here

Need a hint?

Use az acr repository show with --name for the registry and --image for the image name to confirm the image is pushed.
