@jbreiding I could also take a stab at this later, but would you be up for adding an e2e test to the Github CI workflow to ensure that the docker image can be successfully built and when executed exposes a healthy Temporal service endpoint?

Perhaps in another PR.
This would likely entail dockerizing the test worker from this repo or using tctl and maybe combining with a docker-compose example.
