github.com/dotse/go-health (go): Package health contains health checking utilities.  The most interesting part of the API is Register (and RegisterFunc), which is a simple way to set up a health check for ‘anything’.  As soon as any health checks are registered a summary of them is served at http://0.0.0.0:9999.  For services there is `HealthCheckCommand()` to put (early) in `main()`, e.g:  Docker images can then use the following:  See <https://inadarei.github.io/rfc-healthcheck/>.
