Kubernetes has become the dominant platform for container orchestration after starting as an internal Google project. It provides a unified platform for deploying and managing container-based applications across public and private clouds. Kubernetes handles tasks like scheduling, health monitoring, and automated rollouts and rollbacks. It uses controllers to define and manage the desired state for workloads. Many companies have built products that integrate with Kubernetes to provide additional capabilities like service meshes, security tools, and serverless functions. Red Hat focuses on delivering Kubernetes through OpenShift along with capabilities for developers, operators, and a consistent hybrid cloud experience.

- 6. THE HISTORY OF KUBERNETES Google runs all applications on Linux containers. Google internal container orchestrator called “Borg”. CNCF created. Google donates Kubernetes to CNCF for Governance. Open Source community created. Google creates open source version of Borg, called Kubernetes. Creates cloud- agnostic container orchestration. June 2014 December 20152006-Present

- 10. WHAT DOES KUBERNETES PROVIDE? MASTERS: Control plane for Kubernetes • Manage API Server • Manage Scheduler • Manager Cluster Services HOSTS: • Run the Kubelet • Manage tasks assigned by Kubernetes Masters (CSI) STORAGE INTERFACE ORCHESTRATION CLUSTER SERVICES DEPLOYMENT STRATEGIES (CNI) NETWORK INTERFACE HOST KUBELET HOST KUBELET KUBERNETES API
- 11. KUBERNETES CONTROLLERS – MANY WAYS TO DEPLOY APPLICATIONS Replica Sets: A ReplicaSet ensures that a specific number of pod replicas are running at a given time. Usually used in conjunction with a “Deployment”. Deployments: Defines a specific state of a Deployment object. Could be a ReplicaSet, state of a pod, Rollback, etc. StatefulSet: Used for Stateful applications. Creates a sticky identity for pods. DaemonSet: Used for ensure all Nodes run an instance of the pod. Used for cluster-wide services (e.g. Logging, Monitoring, Container Storage, Jobs: Used for “Run to Completion” tasks. CronJob: Used for time-based Jobs, “Run to Completion” tasks. Custom Resources: Collection of additional APIs used to extend existing Kubernetes functionality (also known as “CRDs” Operators: Manage, package and deploy Kubernetes applications, using Day 1 and Day 2 awareness.
