Does readiness imply liveness?

[wujekbogdan]

I implemented my custom readiness check and now I wonder if that's sufficient.

Using common sense, I would assume that readiness implies liveness (if the /ready endpoint responds, then the server must be alive), so I don't need to ping both URLs to verify if the server is healthy AND ready, but the documentation isn't explicit about it.

Yes, the liveness is using the exact same way to respond to HTTP requests, so if the readiness check passes, the liveness should also pass. The readiness check just allows you to add your own custom check to verify all the services used by your server are available, meaning your server is actually ready to serve requests.
