k89s

k8s is a common shorthand for Kubernetes, an open-source system for automating the deployment, scaling, and management of containerized applications. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. Kubernetes allows users to orchestrate a cluster of machines, treating them as a single pool of resources. This abstraction simplifies the deployment and management of complex applications.

At its core, Kubernetes works by managing pods, which are the smallest deployable units of computing that can be created and managed. A pod typically consists of one or more containers, along with shared storage and network resources, and a specification for how to run the containers. Kubernetes also manages services, which provide a stable network endpoint for a set of pods, and deployments, which describe the desired state of applications.

Key features of Kubernetes include automated rollouts and rollbacks, self-healing capabilities, service discovery and load balancing, and storage orchestration. It enables declarative configuration, meaning users define the desired state of their applications, and Kubernetes works to maintain that state. This system is widely adopted by organizations for managing microservices and large-scale applications in cloud and on-premises environments.
