+**Notes:**
+- The `docker_image_name` output is just the repository name (e.g., `my-repo`).
+- The `docker_image_full_name` output is the full image name including registry, domain, and repository (e.g., `myregistry.azurecr.io/infra/my-repo`).
+- Use the outputs in downstream steps, such as for pushing the image.
