What happened?

The registry module fails to start during test suite startup, causing the test engine to kill the test process.

This seems to be due to the particular wait strategy chosen; I can replace it with:

testcontainers.WithWaitStrategy(
	wait.ForMappedPort("5000/tcp"),
),

.... and the container starts right up.

Relevant log output

Additional information

I'm running inside a devcontainer running on podman, with the docker-outside-of-docker feature installed.
For the most part this works really well; I can run all commands as docker ... inside the container (which doesn't even have the podman cli).
For some reason some of the wait strategies seem to be expecting something about network state that renders some of the wait strategies unavailable.

(Also, I have to disable Ryuk because this all is running rootless, but 🤷 )
