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.
Minimum Recommended Setup for a Cluster
- 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.
