Chapter 1. New and changed features

Red Hat Service Interconnect is the Red Hat build of Skupper.

The following features are included in Red Hat Service Interconnect version 2.2:

  • Multi-key listeners provide advanced load balancing and failover capabilities with two distribution strategies: priority for ordered failover and weighted for proportional traffic distribution across multiple routing keys. See Creating a multi-key listener using YAML.
  • HTTP proxy tunnel support allows Skupper links to traverse corporate HTTP CONNECT proxies, enabling deployment in restricted network environments. See Linking sites through an HTTP proxy.
  • Additional Network Observer configuration options provide more flexible observability settings.
  • Dynamic system controller for non-Kubernetes sites enables interactive configuration changes on local system sites without requiring service reloads when using --reload-type auto.

  • The internal.skupper.io/listener label value on listener Services has changed from true to the name of the listener.

    When Skupper creates a Kubernetes Service for a listener, it sets the label internal.skupper.io/listener on that Service. Previously the value was always true; it is now set to the name of the listener resource.
