Health check endpoint

[longngn]

Describe your idea, in simple words.

Many infra management tools like K8s rely on a health check endpoint of service to schedule restart or do alerting. I guess we can GET /v1/checkpoints but not sure if that's hacky.

Why is it a good idea?

It'll be more compatible with existing infrastructures. Ogmios also has a /health endpoint.

Are you willing to work on it yourself?

I haven't dug much into the codebase to understand what should be considered healthy for Kupo.

The GET /v1/checkpoints isn't hacky at all, it's meant to monitor the progress of the underlying syncing process. However, that's more about progress reporting than about health.

I agree that a health endpoint (and command, for containers) would be nice also.
