Kubernetes for the Absolute Beginners - Hands-On - Services – ClusterIP

The video tutorial discusses Kubernetes services and their role in managing communication between different pods in a full-stack web application. It highlights the challenges of using dynamic IP addresses for pod communication and introduces Kubernetes services as a solution to group pods and provide a stable interface for communication. The tutorial explains the creation of a Cluster IP service using a definition file, detailing the necessary components and commands to establish effective communication within a Kubernetes cluster.

• Lack of network protocols

• Dynamic IP addresses

• Static IP addresses

How does a Kubernetes service help in managing pod communication?

• By assigning static IPs to pods

• By grouping pods and providing a single access interface

• By increasing the number of pods

• By reducing the number of network requests

What is the default type of a Kubernetes service?

• ExternalName

• NodePort

• LoadBalancer

• ClusterIP

Which component in the service definition file specifies the port where the service is exposed?

• Ports

• Metadata

• Kind

• API version

What is the purpose of using a selector in a Kubernetes service definition?

• To specify the API version
