Description Standa Laznicka 2020-04-15 13:15:26 UTC
+++ This bug was initially created as a clone of Bug #1809665 +++

The router, console, and oauth endpoints should all gracefully terminate when their pods are marked deleted without dropping traffic.

Console and oauth can have simple "wait before shutdown" logic because they do not execute long running transactions.  The router needs to wait longer (it is a service load balancer) and then instruct HAProxy to gracefully terminate, then wait up to a limit, and then shut down.

In combination these fixes will ensure end users see no disruption of the control plane or web console, or their frontend web applications, during upgrade.
