We're asking the following questions to evaluate whether or not this bug warrants blocking an upgrade edge from either the previous X.Y or X.Y.Z. The ultimate goal is to avoid delivering an update which introduces new risk or reduces cluster functionality in any way. Sample answers are provided to give more context and the UpgradeBlocker flag has been added to this bug. It will be removed if the assessment indicates that this should not block upgrade edges. The expectation is that the assignee answers these questions.
Who is impacted? If we have to block upgrade edges based on this issue, which edges would need blocking?
example: Customers upgrading from 4.y.Z to 4.y+1.z running on GCP with thousands of namespaces, approximately 5% of the subscribed fleet
example: All customers upgrading from 4.y.z to 4.y+1.z fail approximately 10% of the time
What is the impact? Is it serious enough to warrant blocking edges?
example: Up to 2 minute disruption in edge routing
example: Up to 90seconds of API downtime
example: etcd loses quorum and you have to restore from backup
How involved is remediation (even moderately serious impacts might be acceptable if they are easy to mitigate)?
example: Issue resolves itself after five minutes
example: Admin uses oc to fix things
example: Admin must SSH to hosts, restore from backups, or other non standard admin activities
Is this a regression (if all previous versions were also vulnerable, updating to the new, vulnerable version does not increase exposure)?
example: No, it’s always been like this we just never noticed
example: Yes, from 4.y.z to 4.y+1.z Or 4.y.z to 4.y.z+1
I believe this is mostly a dependency backport. The code itself shouldn't be impactful for customers. No edge blocking needed.
