Doc Type:	Bug Fix
Doc Text:	Cause: Certain initialization code was only run when doing a full SDN setup, and not when OpenShift was restarted and found the SDN was already up and running. Consequence: If the atomic-openshift-node service was restarted, that node would be unable to create new per-project static egress IPs (HostSubnet.EgressIPs). Fix: The egress IP initialization code is now run in all circumstances. Result: Per-project static egress IPs work correctly, even after a node restart.

Description Ben Bennett 2018-01-17 15:29:38 EST

+++ This bug was initially created as a clone of Bug #1533153 +++

Description of problem:
After a "simple" restart of a node (such that it doesn't need to re-setup the SDN), newly-created egress IPs won't work correctly

Steps to Reproduce:
1. Start a cluster
2. On one of the nodes, "systemctl restart atomic-openshift-node"
3. Add an auto-egress-IP to that node

Actual results:
Newly-added egress IP doesn't work, and there's an ovs-related error in the journal for that node

Expected results:
Works

https://github.com/openshift/origin/pull/18049 fixes this for master. I'll update when there's a backport to 3.7.

Comment 1 Dan Winship 2018-01-30 11:31:53 EST

fyi I was waiting for https://github.com/openshift/origin/pull/18121 to merge so I could backport them together rather than having to two separate bugs

Comment 4 Meng Bo 2018-02-14 04:21:58 EST

Tested on OCP v3.7.29

The egress IP will work well after the node service restarted on egress node.
And the egress IP works well when the order of OPENSHIFT-MASQUERADE and KUBE-POSTROUING switched.
