Read the first 6 CKA Services and Ingress flashcards as text

  1. What is the fully qualified domain name (FQDN) for service 'myservice' in namespace 'mynamespace'?

    Answer: myservice.mynamespace.svc.cluster.local

    Kubernetes service FQDNs follow the format `..svc.cluster.local`.

  2. Which component provides DNS resolution for service names within a Kubernetes cluster?

    Answer: CoreDNS

    CoreDNS is the default DNS server deployed in Kubernetes clusters since v1.13, resolving service and pod hostnames.

  3. Which Kubernetes object tracks the IP addresses and ports of pods backing a Service?

    Answer: EndpointSlice

    EndpointSlice objects (replacing the older Endpoints object) track the IP/port pairs of pods selected by a Service.

  4. How are individual StatefulSet pods addressed via DNS using a headless service 'mysvc' in namespace 'default'?

    Answer: .mysvc.default.svc.cluster.local

    StatefulSet pods are individually addressable as `...svc.cluster.local`.

  5. What happens when a Service's label selector matches no running pods?

    Answer: The Endpoints object has no entries and traffic to the service is dropped

    When no pods match the selector, the Endpoints/EndpointSlice contains no addresses and traffic sent to the service has no backend to reach.

  6. Which kubectl command (using a short alias) shows the current endpoints for service 'webapp'?

    Answer: kubectl get ep webapp

    `kubectl get ep webapp` uses 'ep' as the short alias for 'endpoints' to display the endpoint IPs backing the service.
