  2. Topics For Today’s DevOps Training 1 What is Kubernetes 2 Discuss the Kubernetes Architecture 3 Components for Master and Worker Nodes 4 Etcd : Cluster State Management 5 Network Setup Requirements KUBERNETES CERTIFICATION TRAINING www.edureka.co/kubernetes-certification

  3. What is Kubernetes? Kubernetes is an open-source Container Management tool which automates container deployment, container (de)scaling & container load balancing. Benefit: Works brilliantly with all cloud vendors: Public, Hybrid & On-Premises. KUBERNETES CERTIFICATION TRAINING www.edureka.co/kubernetes-certification

  4. Features Of Kubernetes 3 1 2 Service Discovery & Load Balancing Storage Orchestration Automatic Binpacking 5 4 6 Secret & Configuration Management Self Healing Batch Execution 7 8 Automatic Rollbacks & Rollouts Horizontal Scaling KUBERNETES CERTIFICATION TRAINING www.edureka.co/kubernetes-certification

  6. Kubernetes Architecture

  7. Kubernetes Architecture ▪ Kubernetes has the following main components: – Master nodes – Worker nodes – Distributed key-value store, like etcd. KUBERNETES CERTIFICATION TRAINING www.edureka.co/kubernetes-certification

  8. Kubernetes Architecture - Master Node ▪ Responsible for managing the Kubernetes cluster ▪ It is the entry point for all administrative tasks ▪ Can be more than one master node in the cluster ▪ Only one of them will be the leader ▪ Kubernetes uses etcd KUBERNETES CERTIFICATION TRAINING www.edureka.co/kubernetes-certification

  9. Master Node Components

  10. Kubernetes Architecture - Master Node Components ▪ A master node has the following components: – API server – Scheduler – Controller manager – etcd. KUBERNETES CERTIFICATION TRAINING www.edureka.co/kubernetes-certification
