Kubernetes (often referred to as “K8s”) is an open-source container orchestration system for automating the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF).
What Is Kubernetes?
Kubernetes provides a platform-agnostic way to manage and scale containerized applications, making it easier to run and manage applications in a distributed environment. It is widely used in the industry for container orchestration. Some of the main features of Kubernetes include:
- Automated container deployment, scaling, and management: Kubernetes automates the process of deploying, scaling, and managing containerized applications, making it easier to run and manage applications in a distributed environment.
- Service discovery and load balancing: Kubernetes provides built-in service discovery and load balancing, allowing applications to automatically discover and communicate with each other.
- Automatic storage provisioning: Kubernetes can automatically provision and manage storage for containerized applications, including local and external storage options.
- Self-healing: Kubernetes can automatically detect and recover from failures, ensuring that applications remain available and running.
- Automatic rollouts and rollbacks: Kubernetes can automatically roll out and roll back updates to containerized applications, making it easier to manage and maintain applications.
- Horizontal scaling: Kubernetes can automatically scale up or down the number of replicas of a containerized application in response to changing demand.
- Namespaces: Kubernetes allows for the organization of resources within a cluster by creating multiple virtual clusters backed by the same physical cluster.
- Pluggable architecture: Kubernetes allows the use of various cloud providers or on-premise infrastructure and allows for customization of the control plane and the container runtime.
