 The Docker images are used as the basis for Jenkins build nodes as well as a custom GitHub action for testing the various THREDDS projects.
 The image is based off the latest available image for `ubuntu 24.04`.
 The docker images produced by packer are called "thredds-test-environment" (for use by Jenkins) of `thredds-test-action` (for use by the GitHub action).
+The image used by Jenkins is hosted on the Docker Hub Container Registry, while the image used by the GitHub action is hosted on the GitHub Container Registry.
