Kubernetes Tutorial

Kubernetes is an open-source container management platform.

• Automates the deployment, management, and scaling of container-based applications.
• Developed at Google in 2014, Kubernetes draws on Google’s production experience and is now maintained by the Cloud Native Computing Foundation.
• It orchestrates containers grouping them into logical units called pods and managing their lifecycle across a cluster of machines.
• It automatically restarts failed containers, replaces them when necessary, and reschedules workloads onto healthy nodes to maintain the desired state.

Basics of Kubernetes

Kubernetes is like a ship captain for containers, organizing and placing them on multiple computers (like a ship carrying many containers). This introduction will explain key Kubernetes ideas like Pods, Services, and Deployments.
