Kubernetes (commonly referred to as “K8s”) is an open source system for automating deployment, scaling and management of containerized applications that was originally designed by Google and donated to the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. It usually works with the Docker container tool and coordinates between a wide cluster of hosts running Docker. Other includes Docker Swarm, DC/OS, MESOS, AWS ECS.
