MicrosoftContainer Orchestration and Kubernetes:
Kubernetes is a popular container orchestration platform that automates the deployment, scaling, and management of containerized applications. It's a critical skill for DevOps professionals working with microservices and containerized applications. Here are some key points that you might need to know about Kubernetes for the exam:
Kubernetes Architecture: Understand the core components of Kubernetes, including the Master Node (API server, controller manager, etcd, and scheduler) and Worker Nodes (kubelet, kube-proxy, and container runtime).
Pods: Comprehend the concept of pods, which are the smallest deployable units in Kubernetes. Know how to define and manage pods, including multi-container pods.
Deployments: Learn about Deployments, which provide declarative updates to applications. Understand how they manage the desired state, rolling updates, and rollbacks.
Services: Understand the role of Services in exposing applications within the cluster or to external traffic. Differentiate between ClusterIP, NodePort, and LoadBalancer service types.
ReplicaSets: Know how ReplicaSets ensure a specified number of replicas of a pod are running at all times. Understand their relationship with Deployments .
Container orchestration is the practice of automating the deployment, scaling, and management of containerized applications, and Kubernetes is the industry-standard platform for achieving this.
