Epic Goal

• Make the image registry distributed across availability zones.

Why is this important?

• The registry should be highly available and zone failsafe.

Scenarios

1. As an administrator I want to rely on a default configuration that spreads image registry pods across topology zones so that I don't suffer from a long recovery time (>6 mins) in case of a complete zone failure if all pods are impacted.

Acceptance Criteria

• CI - MUST be running successfully with tests automated
• Release Technical Enablement - Provide necessary release enablement details and documents.

Dependencies (internal and external)

1. Pod's topologySpreadConstraints
