title: How do you find the cluster & service CIDR of a Kubernetes cluster?
body: <p>How do you find the cluster/service CIDR for a Kubernetes cluster, once it is already running?</p>
  
  <p>I know for Minikube, it is 10.0.0.1/24.</p>
  
  <p>For GKE, you can find out via</p>
  
  <pre><code>gcloud container clusters describe XXXXXXX --zone=XXXXXX |
    grep -e clusterIpv4Cidr -e servicesIpv4Cidr
  </code></pre>
  
  <p>But how do you find out on a generic Kubernetes cluster, particularly via <code>kubectl</code>?</p>
