Multicluster Ingress (MCI) is useful for a variety of scenarios: high-availability services, low-latency access, setting up hybrid multi-cloud and on-prem architectures, canarying clusters with new release versions and running experimental releases.In this talk, we will show how we can leverage the Cluster Registry to create multicluster ingresses with Kubernetes-style semantics. Using a controller against the Cluster Registry server, we can watch multicluster ingress resources and the list of clusters. This allows us to manage MCIs and automatically add/remove them from clusters as they are added/removed from the registry using label selection.We will also demo a sample application and show how users can make it resilient to cluster failures using multi cluster ingress.
