CoreOS

Introduction> Introduction # Kubernetes is a powerful open-source system, initially developed by Google and supported by the Cloud Native Computing Foundation (CNCF), for managing containerized applications in a clustered environment. It aims to provide better ways of managing related, distributed components and services across varied infrastructure.

Introduction> Introduction # CoreOS allows you to easily run services in Docker containers across a cluster of machines. The procedure for doing so usually involves starting one or multiple instances of a service and then registering each instance with etcd, CoreOS’s distributed key-value store.

Introduction> Introduction # One of the technologies that makes CoreOS possible is etcd, a globally distributed key-value store. This service is used by the individual CoreOS machines to form a cluster and as a platform to store globally-accessible data.
