Ask an OpenShift Admin (Ep 23): DNS and cluster networking

DNS forms the backbone of service discovery, both internally and externally, with OpenShift. Did you know OpenShift has separate DNS for Pods and nodes? This episode we’re joined by Christian Hernandez, DNS expert and Technical Marketing Manager for OpenShift, to talk about how DNS is used and configured for both Pods and nodes in the cluster. We’ll also discuss external DNS requirements for connecting to applications hosted by OpenShift. About Ask an OpenShift Admin: Do you have questions? We want to answer them!
