Kubernetes
What is Kubernetes?
Kubernetes, often abbreviated as K8s, is an open-source platform designed to automate deploying, scaling, and operating application containers. Originally developed by Google, Kubernetes has become the de facto standard for container orchestration and is now maintained by the Cloud Native Computing Foundation (CNCF).
Key Features of Kubernetes
- Automated Deployment: Simplify the deployment process with automated rollouts and rollbacks.
- Scaling and Load Balancing: Automatically scale your applications and distribute traffic across containers.
- Self-Healing: Automatically restart or replace containers that fail or become unresponsive.
- Service Discovery and Load Balancing: Easily expose services to the network and load-balance traffic between containers.
- Storage Orchestration: Automatically mount storage systems like local storage, public cloud providers, and more.
- Configuration Management: Manage application configuration and secrets securely.
- Multi-Cloud and Hybrid Cloud Support: Deploy and manage applications across various cloud providers and on-premises environments.
Components of Kubernetes
Kubernetes is composed of several key components that work together to provide a robust container orchestration platform:
- Master Node: Manages the Kubernetes cluster and coordinates the worker nodes.
- Worker Nodes: Run containerized applications and provide the resources for the Kubernetes system.
- Pods: The smallest deployable units in Kubernetes, consisting of one or more containers.
- Services: Define a logical set of Pods and a policy by which to access them.
- Deployments: Manage the deployment of Pods and ensure that the desired state of the application is met.
