Exercise - Build container image for your ASP.NET app

  • 8 minutes

For this exercise, we use Azure Container Registry and its features to build and store the container images. The Azure Container Registry allows you to build, store, and manage container images and artifacts in a private registry for all types of container deployments. Azure Migrate: App Containerization uses Azure Container Registry Tasks to build container images in Azure on-demand and then store those images.

Build container image

  1. Create Azure Container Registry: Create a new Azure Container Registry to build and store the container images for the apps. Select the create new registry option to create a new ACR learnappcontainerizationacr.

    Screenshot for app ACR selection.

  2. Review the Dockerfile: The Dockerfile needed to build the container images for each selected application are generated at the beginning of the build step. Select Review to review the Dockerfile. You can also add any necessary customizations to the Dockerfile in the review step and save the changes before starting the build process. In this exercise, we don't make any changes to the Dockerfile.

  3. Trigger build process: Select the application to build images for, and select Build. Selecting Build starts the container image build for each application. The tool keeps monitoring the build status continuously and lets you proceed to the next step upon successful completion of the build.

  4. Track build status: You can also monitor progress of the build step by selecting the Build in Progress link under the status column. The link takes a couple of minutes to be active after you trigger the build process.

  5. Once the build is completed, select Continue to specify deployment settings.
