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.

If using `docker-jenkins`, then once the image is built you can test out the environment by using:

~~~bash
docker run -i -t --rm docker.unidata.ucar.edu/thredds-test-environment:24.04
docker run -i -t --rm docker.io/unidata/thredds-test-environment:24.04
~~~

These images are built using the multiplatform feature of Docker, and only `linux/amd64` images are produced.
If you are on a `arm64` based mac, you will need to run:

~~~bash
DOCKER_DEFAULT_PLATFORM=linux/amd64 docker run -i -t --rm docker.unidata.ucar.edu/thredds-test-environment:24.04
DOCKER_DEFAULT_PLATFORM=linux/amd64 docker run -i -t --rm docker.io/unidata/thredds-test-environment:24.04
~~~

Note that images are not pushed as part of this build process.
Pushes can be done via the normal docker mechanisms, e.g. `docker image push docker.unidata.ucar.edu/thredds-test-environment:24.04` and `docker image push ghcr.io/unidata/thredds-test-action:v3`.
