When you use the ACR to store the image and want to deploy the images in it to Azure Web App, you need to set the image name as ACRName.azurecr.io/image:tag, not just the image name and tag. And set the environment variables like:
DOCKER_REGISTRY_SERVER_USERNAME - The username for the ACR server.
DOCKER_REGISTRY_SERVER_URL - The full URL to the ACR server. (For
example, https://my-server.azurecr.io.)
DOCKER_REGISTRY_SERVER_PASSWORD - The password for the ACR server.
And the credential should have enough permissions. When all things are OK, the container logs will look like this:
