    Description

      NetworkGateway endpoints can be transmitted as DNS names by the remote cluster, in which case the local cluster has to first resolve them to a set of IP addresses before it uses them as routable service endpoints. Transmitting DNS names has the advantage that they're rather stable, but it does mean the receiving end has to resolve them in regular intervals - ideally periodically, everytime their TTL has passed.

       

      ACs:

      • network gateway endpoints that are hostnames are resolved by the receiving istiod automatically
      • (optional) period is automatically derived from DNS entry's TTL

          Sub-task - The sub-task of the issue MAISTRA-2293 Create CRD for joining meshes into a federated mesh

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          Task - Represents a small unit of work that is not end-user facing. MAISTRA-2240 Investigate how we determine public IP for routing between clusters

          • Critical - To be worked on immediately following BLOCKER issues.
