k0s - The Zero Friction Kubernetes#
k0s is an open source, all-inclusive Kubernetes distribution, which is configured with all of the features needed to build a Kubernetes cluster. Due to its simple design, flexible deployment options and modest system requirements, k0s is well suited for
- Any cloud
- Bare metal
- Edge and IoT
k0s drastically reduces the complexity of installing and running a CNCF certified Kubernetes distribution. With k0s new clusters can be bootstrapped in minutes and developer friction is reduced to zero. This allows anyone with no special skills or expertise in Kubernetes to easily get started.
k0s is distributed as a single binary with zero host OS dependencies besides the host OS kernel. It works with any Linux without additional software packages or configuration. Any security vulnerabilities or performance issues can be fixed directly in the k0s distribution that makes it extremely straightforward to keep the clusters up-to-date and secure.
