Inside an OKE cluster, the clerk portal must call the checkout service. Which Service type provides a stable in-cluster virtual IP that forwards to ready Pods and is not itself a public internet front door?
Select an answer to reveal the explanation.
Short Explanation
ClusterIP is the inside voice of the cluster: a stable virtual IP for Pod-to-Pod calls. It tracks ready backends and is not exposed to the public internet by itself. Call checkout by service name, not by chasing Pod IPs.
Full Explanation
ClusterIP is the default in-cluster Service type: it allocates a stable virtual IP and forwards to ready Pods selected by labels. It is the right choice for internal microservice calls. It is not reachable from the public internet without additional exposure. LoadBalancer is for external provisioning patterns; hard-coding node or Pod IPs defeats service discovery.
