Ace Your Next Kubernetes Interview! 1. **What is Kubernetes, and why is it used?** **Answer:** Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It’s used to improve application reliability and scalability while simplifying operations. 2. **Can you explain the concept of Pods in Kubernetes?** **Answer:** A Pod is the smallest deployable unit in Kubernetes. It can contain one or more containers that share the same network namespace and storage. Pods allow co-located applications to share resources and communicate efficiently. 3. **What are Deployments, and how do they differ from ReplicaSets?** **Answer:** A Deployment is a higher-level abstraction that manages the creation and updating of Pods. It ensures that the desired number of Pods is running at all times. ReplicaSets, on the other hand, maintain a stable set of replica Pods, ensuring the specified number of Pods are running but without providing the deployment capabilities. 4. **What is a Service in Kubernetes?** **Answer:** A Service in Kubernetes is an abstraction that defines a logical set of Pods and a policy for accessing them. It provides stable network endpoints and load balancing, allowing Pods to communicate with each other regardless of their IP addresses. 5. **How does Kubernetes handle configuration management?** **Answer:** Kubernetes uses ConfigMaps and Secrets to manage configuration data. ConfigMaps store non-sensitive data, while Secrets are used to store sensitive information like passwords or API keys, ensuring that these values are secured and accessed securely by Pods. #Kubernetes #Interviews #TechCareers #DevOps #ContainerOrchestration #K8s

For a Kubernetes interview, you should be familiar with these important terms: Pod: The smallest deployable unit in Kubernetes, consisting of one or more containers that share storage and networking. Deployment: A Kubernetes resource that manages stateless applications by ensuring a specified number of pod replicas are running. ReplicaSet: Ensures a specified number of pod replicas are running at any given time, often managed by a Deployment. Service: Exposes a set of pods as a network service, abstracting the underlying pod IPs and allowing for load balancing. Namespace: Provides a way to divide cluster resources between multiple users or applications, helping with resource isolation. ConfigMap: Allows you to decouple configuration artifacts from container images to keep containerized applications portable. Secret: Stores sensitive information, such as passwords, OAuth tokens, and ssh keys, securely. StatefulSet: Manages stateful applications by maintaining a sticky identity for each pod and handling deployments and scaling. DaemonSet: Ensures that a copy of a pod runs on all (or some) nodes in the cluster, typically used for cluster-wide services. Job: Creates one or more pods to perform a task until completion and ensures that the task is executed successfully. CronJob: Allows you to run jobs on a scheduled basis, similar to cron jobs in Unix-based systems. Horizontal Pod Autoscaler (HPA): Automatically scales the number of pod replicas based on observed CPU utilization or other select metrics. Persistent Volume (PV): Represents a piece of storage in the cluster that has been provisioned by an administrator. Persistent Volume Claim (PVC): A request for storage by a user, which binds to a Persistent Volume. Ingress: Manages external access to services, typically HTTP, providing load balancing, SSL termination, and name-based virtual hosting. RBAC (Role-Based Access Control): Manages permissions and access control within the Kubernetes cluster. Service Account: Provides an identity for processes running in a pod to interact with the Kubernetes API. Helm: A package manager for Kubernetes, used to deploy and manage applications and services with predefined charts. Kubectl: The command-line tool used to interact with and manage Kubernetes clusters. Cluster Autoscaler: Automatically adjusts the size of the Kubernetes cluster based on resource requests and usage. #kubernetes #devops #interview #hiring #interviewpreparation
