2-Push Image To ACR.md

Push Image To Azure Container Registry (ACR)

🎯 Purpose

In this lab, you'll push the Docker image you created locally to Azure Container Registry (ACR).

🛠️ Push Docker Image to ACR

Prerequisites

• Docker image created locally
• Access to an Azure Container Registry

Steps

1. Log Into the ACR Repository

🔍 Note: Replace devopsthehardwayazurecr with your actual ACR name.

az acr login --name devopsthehardwayazurecr

2. Tag the Docker Image

🔍 Note: Ensure to replace devopsthehardwayazurecr with your ACR name and v1 with the appropriate version tag if needed.

docker tag thomasthorntoncloud devopsthehardwayazurecr.azurecr.io/thomasthorntoncloud:v1

3. Push the Docker Image to ACR

   docker push devopsthehardwayazurecr.azurecr.io/thomasthorntoncloud:v1

🧠 Knowledge Check

After pushing the image to ACR, consider these questions:

1. Why do we need to tag the Docker image before pushing it to ACR?
2. What's the significance of the version tag (e.g., v1) in the image name?
3. How does ACR authentication work when pushing images?

🔍 Verification

To ensure the Docker image was successfully pushed to ACR:

1. Log into the Azure Portal.
2. Navigate to your Azure Container Registry
3. Check the "Repositories" section to see if your image is listed:

💡 Pro Tip

Consider setting up CI/CD pipelines to automatically build and push your Docker images to ACR whenever you make changes to your application code.
