In order to achieve this, they removed a lot of extra drivers that didn't need to be part of the core and are easily replaced with add-ons. K3s is a fully CNCF (Cloud Native Computing Foundation) [certified Kubernetes](https://www.cncf.io/certification/software-conformance/) offering. This means that you can write your YAML to operate against a regular "full-fat" Kubernetes and they'll also apply against a k3s cluster. Due to its low resource requirements, it's possible to run a cluster on anything from 512MB of RAM machines upwards. This means that we can allow pods to run on the master, as well as nodes. And of course, because it's a tiny binary, it means we can install it in a fraction of the time it takes to launch a regular Kubernetes cluster! We generally achieve sub-two minutes to launch a k3s cluster with a handful of nodes, meaning you can be deploying apps to learn/test at the drop of a hat." * [**k3sup (said 'ketchup')**](https://github.com/alexellis/k3sup) is a light-weight utility to get from zero to KUBECONFIG with k3s on any local or remote VM.

It is specifically designed to only have what is needed to run k3s. Additionally the OS is designed to be managed by kubectl once a cluster is bootstrapped. Nodes only need to join a cluster and then all aspects of the OS can be managed from Kubernetes.

Specifically k3c focuses on developing and running local containers, basically docker run/build. Currently k3s, the [lightweight Kubernetes distribution](https://github.com/rancher/k3s), provides a great solution for Kubernetes from dev to production. While k3s satisifies the Kubernetes runtime needs, one still needs to run docker (or a docker-like tool) to actually develop and build the container images. k3c is intended to replace docker for just the functionality needed for the Kubernetes ecosystem. + ##### Hosted Rancher * [Announcing **Hosted Rancher** with Rancher 2.4 🌟🌟🌟](https://rancher.com/blog/2020/announcing-hosted-rancher)
