Description Sam Batschelet 2019-11-07 20:58:25 UTC

+++ This bug was initially created as a clone of Bug #1769985 +++

Description of problem: openshift/kubecsr repo is the canonical home for etcd cert signer. PR #22 added client usage and was merged upstream and is part of master downstream.[1] 

[1]: https://github.com/openshift/kubecsr/commit/aad75d333646da657e788db93f2ff75da850b542#diff-654ba8df3be94fe94c9404a7727d1fa2

But this was never backported to the openshift-4.1, openshift-4.2 or openshift-4.3. With etcd 3.3.10 the result is an error message during startup 

> 2019-11-07 14:18:08.592903 I | embed: rejected connection from "127.0.0.1:32972" (error "tls: failed to verify client's certificate: x509: certificate specifies an incompatible key usage", ServerName "")


In 3.3.17 we see many more of these errors and the result will be unnecessary bugs and spammy logs.

Linking the 4.2 backport, while we wait for the Bugzilla bot to get fixed.
