Automatic merge from submit-queue (batch tested with PRs 49989, 49806, 49649, 49412, 49512) This adds an etcd health check endpoint to kube-apiserver addressing https://github.com/kubernetes/kubernetes/issues/48215. **What this PR does / why we need it**: This ensures kube-apiserver `/healthz` endpoint fails whenever connectivity cannot be established to etcd, also ensures the etcd preflight checks works with unix sockets **Which issue this PR fixes**: fixes #48215 **Special notes for your reviewer**: This PR does not use the etcd client directly as the client object is wrapped behind the storage interface and not exposed directly for use, so I decided to reuse what's being done in the preflight. So this will only check fail for connectivity and not etcd auth related problems. I did not write tests for the endpoint because I couldn't find examples that I could follow for writing tests for healthz related endpoints, I'll be willing to write those tests if someone can point me at a relevant one. **Release note**: ```release-note Add etcd connectivity endpoint to healthz ``` @deads2k please help review, thanks! |
