The pipeline uses the [Create Image Script](../ml_service/util/create_scoring_image.py) to create a scoring image. The image will be registered under an Azure Container Registry instance that belongs to the Azure Machine Learning Service. Any dependencies that the scoring file depends on can also be packaged with the container with an image config. Learn more about how to create a container using the Azure ML SDK with the [Image class](https://docs.microsoft.com/en-us/python/api/azureml-core/azureml.core.image.image.image?view=azure-ml-py#create-workspace--name--models--image-config-) API documentation.

Make sure your webapp has the credentials to pull the image from the Azure Container Registry created by the Infrastructure as Code pipeline. Instructions can be found on the [Configure registry credentials in web app](https://docs.microsoft.com/en-us/azure/devops/pipelines/targets/webapp-on-container-linux?view=azure-devops&tabs=dotnet-core%2Cyaml#configure-registry-credentials-in-web-app) page. You'll need to run the pipeline once (including the Deploy to Webapp stage up to the `Create scoring image` step) so an image is present in the registry. After that, you can connect the Webapp to the Azure Container Registry in the Azure Portal.

The pipeline should create the webapp automatically the first time it is run with **WEBAPP_DEPLOYMENT_NAME** set.
