Managing CoreDNS

“

- In this lesson, you will learn what you can do to manage CoreDNS. So, the coredns Deployment runs in the kube-system Namespace, and until a network plugin is available, the coredns Pods will show a status of pending. So, if you ever see your CoreDNS Pods in a state of pending, that probably means you need to install a network namespace. The CoreDNS configuration is maintained in the CoreDNS ConfigMap, and any changes to the configuration, such as adding an external DNS forwarder for instance, need to be added to this ConfigMap. So, this is what the relevant section in the ConfigMap might look like, and that's all that you need to know about managing CoreDNS.
