Kubernetes is Google’s open-source container orchestration framework. In fact, they go in a bunch of Docker - Microservices - Kubernetes.

Kubernetes allows you to install and deploy your application in seconds, and it has the functionality of a Health Check. If the application does not work properly, we kill it, restart it on another machine. If one of the nodes of your cluster falls out, we transfer our applications to another. This is all done automatically.

The orchestration describes how the services should interact with each other and in this niche kubernetes is not the only orchestrator, Docker Swarm Mesos, Nomad and others breathe in his back.
