OpenShift Container Platform SDN Hosted Egress IP's are not being scheduled to nodes after upgrade to 4.8
Issue
- A deadlock in OCP SDN egress IP management was found, causing the SDN and thus OCP internal networking to stop working as expected.
- Post update to 4.8.12, Egress IP's are not scheduled to any node via automatic namespace allocation using openshift-SDN network type.
- Experiencing a total loss of all egress IP addresses (previously functional in 4.7.x pre-update) across all nodes - nodes are simply not having the egress IP allocated to the internal networks, despite validating egress cidr and egress IP allocation in automatic mode
Environment
- Red Hat OpenShift Container Platform (OCP) 4.7 and 4.8
