# NAME
kube-apiserver \- Provides the API for kubernetes orchestration.

# SYNOPSIS
**kube-apiserver** [OPTIONS]

# DESCRIPTION

The **kubernetes** API server validates and configures data for 3 types of objects: pods, services, and replicationControllers. Beyond just servicing REST operations, the API Server does two other things as well: 1. Schedules pods to worker nodes. Right now the scheduler is very simple. 2. Synchronize pod information (where they are, what ports they are exposing) with the service configuration.
