What is a Kubernetes service with no cluster IP address called?
A Headless Service in Kubernetes is a type of service that does not have a cluster IP address. This type of service directly maps to the pods it manages, allowing for direct communication with the individual pods using their unique IP addresses. This is useful for certain scenarios like stateful applications where you might want to interact with specific instances of your application directly.
A. Headless Service Here's why: Headless Service: This type of service doesn't have a cluster IP address assigned. Instead, it maps directly to the pods it manages, allowing communication with individual pods using their unique IP addresses. Nodeless Service: This term isn't commonly used in Kubernetes. Services can exist and function even without a dedicated node running them. IPLess Service: While this might seem like a logical term, "Headless Service" is the official designation in Kubernetes. Specless Service: A service definition requires a specification file (usually YAML). A service without a spec wouldn't be a valid service at all
