CKA: Conceitos principais | DevSecOps and Platform Engineering Knowledgement

📄️ Cluster Architecture

Kubernetes cluster architecture: control plane components, worker nodes, ETCD, scheduler, controller manager, API server, kubelet and kube-proxy

ETCD in Kubernetes: distributed key-value database that stores all cluster information, configurations, secrets, pods and states

Kubernetes Kube-ApiServer: central component that manages all cluster operations, authentication, authorization and communication with ETCD

Kubernetes Kube Controller Manager: manages cluster controllers, monitors nodes and pods, ensures desired state and high availability

Kubernetes Kube-Scheduler: responsible for deciding which node will execute each pod based on resources, taints, tolerations and affinities

Kubernetes Kube Proxy: responsible for managing network connectivity between pods and services through iptables and ipvs

Complete review of Kubernetes core concepts: pods, replica sets, deployments, services, namespaces, daemonsets and networking

How to download Kubernetes binaries: kube-apiserver, kube-controller-manager, kube-scheduler and kubectl for manual installation

Essential tips for the CKA exam: kubectl commands to create pods, deployments and services with dry-run and practical examples
