Health check for container

[toni-rib-skydio]

We have a service that uses sish as part of many services in a docker-compose.yml. All of the services minus sish expose some kind of health check we can use to ensure it's up and responding. Would it be possible to add something like that?

Just getting back to this:

Yep, that should be doable. Healthchecking sish's root for a 302 or a 404 doesn't work for you?

So the issue that I've been running into is that with the entrypoint to the container being /app/app, it isn't exposing anything like wget, curl, even sh that I can use as part of a kubernetes health check in our docker-compose.yml to check against the root. Other things we are running like prometheus have this exposed so I can add something like this, where fast_healthcheck just defines the interval, timeout, retries, etc.

    healthcheck:
      test: wget --spider -q http://localhost:9090/-/healthy || exit 1
      <<: *fast_healthcheck

So far I haven't been able to get anything to work with sish that would be somewhat of an equivalent just to say "yes this container is running and healthy."
