Migrate zones between global CPs without breaking cross-zone traffic #8211

Open lobkovilya opened 11 months ago

lobkovilya commented 11 months ago

Description

  1. zone-1 and zone-2 connected to global-cp-old and there is cross-zone traffic
  2. connect zone-1 to global-cp-new, zone-ingress-2 is not synced yet, so cross-zone traffic doesn't work
  3. connect zone-2 to global-cp-new, zone-ingress-2 is synced, and cross-zone traffic works again

If we somehow allow syncing zoneIngresses up first, we can have cross-zone traffic working on step 2.

Triage: could it be an option in the zone to pause sync of zoneIngresses?

@jakubdyszkiewicz is it somehow different with MeshMultizoneService? Or we still need a way to sync ZoneIngresses manually?

While we don't need to sync ZoneIngress, we need to sync MeshServices, so I think the issue would still exist.
