What's the feature?
Be able to enable HealthServer, even if not running under docker.
For use for something like UptimeKuma.
Extra information?

I figured that the HealthServer runs only in docker, but I couldn't find it in the docs so I dig down to:
f4e1cca222/cmd/updater/main.go (L347-L352)

In the latest program (build it until the next release), you can now set --health-server-address=127.0.0.1:9999 for example, to enable the health server to run. By default that health server address defaults to the empty string, meaning the server is disabled, and with the Docker image it defaults to 127.0.0.1:9999 using the docker image environment variable:

e10d778e5f/Dockerfile (L106)

So with all this we have:

standalone binary: no health server by default, but it can be enabled
docker image: health server on by default, and it can be disabled for whatever obscure reason 😄
