Bug 1410128 - [3.4] http traffic failures when accessing pod from outside of the cluster
Summary: [3.4] http traffic failures when accessing pod from outside of the cluster
Alias: None
Product: OpenShift Container Platform
Classification: Red Hat
Component: Networking

Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: The IP addresses for a node were not sorted. Consequence: When the first is chosen, it may be different from the last one used, so the IP address would appear to have changed. OpenShift would update the node -> IP mapping and that causes problems with everything moving from one interface to another. Fix: Sort the addresses. Result: The traffic flows correctly and the addresses don't change.

Tested with OCP build

Issue has been fixed.
No IP flip-flop in master log, and the route can be accessed without 503.
