gRPC probes with the different security configurations of the endpoints #30804

Closed SergeyKanzhelev closed 7 months ago

SergeyKanzhelev commented 2 years ago

This is a Feature Request

Starting 1.23, gRPC probes are built-in to k8s. https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#define-a-grpc-liveness-probe

It will be great to expand documentation explaining which secure endpoint settings will be respected and which wouldn't. Built-in gRPC probe will ignore certificate for TLS, but will likely not work with mutual TLS.

Need to work thru various configurations of endpoint setting and list whether it is supported by the built-in gRPC probe.

also can publish recommendation on testing gRPC endpoints by exposing plaintext endpoint and using TCP check. Like here: https://cloud.google.com/traffic-director/docs/security-proxyless-setup#create-health-check
