- Kubernetes coordinates a highly available cluster of computers that are connected to work as a single unit. The abstractions in Kubernetes allow you to deploy containerized applications to a cluster without tying them specifically to individual machines. To make use of this new model of deployment, applications need to be packaged in a way that decouples them from individual hosts: they need to be containerized. Containerized applications are more flexible and available than in past deployment models, where applications were installed directly onto specific machines as packages deeply integrated into the host. Kubernetes automates the distribution and scheduling of application containers across a cluster in a more efficient way. Kubernetes is an open-source platform and is production-ready. + Kubernetes coordinates clusters of computers. These computers work as a single unit. Kubernetes allows you to deploy applications in containers to a cluster. It does this without tying them to a single machine. To use this deployment model, we first disconnect applications from their individual hosts. In other words, we put them in containers. Such applications are more flexible and available. In past deployment models, we would install applications onto specific machines + as packages. These apps would be integrated into the host. Kubernetes distributes and schedules these containers. Kubernetes is open-source and ready to go live.
A Kubernetes cluster consists of two types of resources:
- Kubernetes is a production-grade, open-source platform that orchestrates the placement (scheduling) and execution of application containers within and across computer clusters. + Kubernetes is a production-grade, open-source platform that schedules and executes container clusters
