| What is AKS (Azure Kubernetes Service) and its Key Features? Answer: AKS is Microsoft Azure's managed container orchestration service, based on Kubernetes. Key features include integrated CI/CD experiences, enterprise-grade security and governance, simplified cluster management, automatic scaling, and integration with other Azure services. What is kubectl and What is its Role in Kubernetes? Answer: kubectl is the command-line tool for interacting with the Kubernetes API server. It allows users to deploy applications, inspect and manage cluster resources, and view logs. kubectl converts command-line requests into API calls and communicates with the Kubernetes cluster to execute these requests. How Do You Create and Manage Resources in Kubernetes Using kubectl? Answer: Resources in Kubernetes can be created using kubectl by applying YAML or JSON configuration files. Commands like kubectl create, apply, delete, and edit are used to manage these resources. For example, kubectl apply -f deployment.yaml would create or update resources defined in deployment.yaml. Explain How to Use kubectl for Debugging Pods and Services. Answer: kubectl provides various commands for debugging, such as: kubectl logs to retrieve logs from a container in a Pod. kubectl describe to see detailed information about resources. kubectl exec to execute commands inside a container. kubectl get to list resources and check their status. These commands help diagnose issues and understand the state of the cluster. Describe the Canary Deployment Pattern in Kubernetes. Answer: Canary deployment involves rolling out a new version of an application gradually to a subset of users to ensure stability before a full rollout. In Kubernetes, this can be achieved by deploying a new version of the application (canary version) and slowly routing a small percentage of traffic to it. Based on the feedback and performance, the traffic is gradually increased until the canary version is serving all the traffic. | ||||
