How to Push a Local Docker Image to Azure Container Registry

Introduction: Azure Container Registry (ACR) is a secure and private registry service provided by Azure for storing and managing Docker container images. Pushing a local Docker image to ACR allows you to store and distribute your custom images in the cloud. In this tutorial, we will walk through the steps to push a local Docker image to Azure Container Registry. Prerequisites:

1. Docker?installed on your local machine.
2. An Azure Container Registry instance set up in your Azure account. You can follow the official?Azure documentation?to create an ACR instance.

Step 1: Log in to Azure Container Registry: To begin, open a command prompt or terminal window and log in to your Azure Container Registry using Docker. Run the following command, replacing?<acrLoginServer>,?<acrUsername>, and?<acrPassword>?with your ACR credentials:

docker login <acrLoginServer> --username <acrUsername> --password <acrPassword>        

Step 2: Tag the Local Image: Before pushing the image, you need to tag it with the Azure Container Registry login server address. Use the following command to tag the local image:

docker tag <localImageName> <acrLoginServer>/<imageName>:<tag>        

Replace?<localImageName>?with the name of your local image,?<acrLoginServer>?with the ACR login server URL,?<imageName>?with the name you want to give to the image in ACR, and?<tag>?with the specific version or tag for the image.

Step 3: Push the Image: To push the tagged image to Azure Container Registry, execute the following command:

docker push <acrLoginServer>/<imageName>:<tag>        

Replace?<acrLoginServer>,?<imageName>, and?<tag>?with the values you used in the previous step.

Step 4: Wait for the Image Upload: Docker will now push the image from your local machine to Azure Container Registry. The time required for the upload will depend on the image size and network speed.

Conclusion: By following these simple steps, you can push a local Docker image to Azure Container Registry, enabling you to store, manage, and distribute your custom container images in a secure and scalable manner. Azure Container Registry provides a reliable solution for container image storage and simplifies the deployment of containerized applications.
