+## GitHub Action
+1. The [GitHub action](https://docs.github.com/en/actions/quickstart) configuration in [/.github/workflows/ccm.yml](../.github/workflows/ccm.yml) uses Dockerfile to build the app, then pushes the image to the [GitHub container registry (GHCR)](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry).
+2. The action is triggered whenever a commit is made to the `main` branch.  E.g., when a pull request is merged to `main`.
+3. OpenShift projects can periodically pull this image from GHCR.  Configure only **_NON-PRODUCTION_** CCM projects to pull the image…
+    ```sh
+    oc tag ghcr.io/tl-its-umich-edu/canvas-course-manager-next:latest canvas-course-manager-next:latest --scheduled --reference-policy=local
+    ```
+    See the OpenShift documentation "[Managing image streams: Configuring periodic importing of image stream tags](https://docs.openshift.com/container-platform/4.11/openshift_images/image-streams-manage.html#images-imagestream-import_image-streams-managing)" for details.
+
+    `reference-policy=local` : If you want to instruct OpenShift Container Platform to always fetch the tagged image from the [integrated registry](https://docs.openshift.com/container-platform/4.11/openshift_images/managing_images/tagging-images.html#images-add-tags-to-imagestreams_tagging-images)
