    Study Notes

    Key Benefits of Kubernetes

    • Simplifies container orchestration, enabling efficient deployment, scaling, and management of applications in microservices architecture.
    • Provides resilience through features like automatic scaling and self-healing, improving uptime and availability.

    Programming Language

    • Kubernetes is primarily written in Go, a statically typed language known for its concurrency support and performance.

    Container Healing

    • Kubernetes automatically manages container failures by restarting, rescheduling, or replacing failed containers, ensuring minimal service disruption.

    Cloud Native Computing Foundation (CNCF)

    • CNCF is recognized for promoting cloud-native technologies and practices, overseeing projects including Kubernetes, ensuring standards, and fostering community collaboration.

    Application Availability

    • Kubernetes enhances application availability through load balancing, self-healing capabilities, and automatic scaling, allowing applications to maintain performance under varying loads.
    • A minimal Kubernetes cluster typically requires one master node and at least one worker node to manage and run applications effectively.

    API Server Role

    • The API server in the Kubernetes Master node serves as the main entry point for all REST commands, managing the state and configuration of the cluster.

    Manifest File Type

    • A Pod manifest file is used to define the number of pods, specific container images, and resource requirements, guiding the deployment of applications.

    Key Architecture

    • Kubernetes architecture consists of a master node that manages the cluster and worker nodes that run application workloads, ensuring orderly orchestration.

    Manifest File Purpose

    • Writing a manifest file that specifies service type, ports, and selectors in Kubernetes enables configuration of networking and service discovery, facilitating communication between components.
