========================
KubeZero is a pre-configured collection of components deployed onto a bare Kubernetes cluster.
All chosen components are 100% organic OpenSource.
KubeZero is a Kubernetes distribution providing an opinionated, pre-configured container platform
incl. various addons and services.
# Design goals
- Cloud provider agnostic, bare-metal / self-hosted possible
- No vendor lock in
- No closed source solutions
- No vendor lock in, most components are optional and could be exchanged
- Organic OpenSource / open and permissive licenses over closed-source solutions
- No premium services / subscriptions required
- Staying to upstream projects as close as possible
- Minimal custom code
- Work within each community / give back
- Staying and contributing back to upstream projects as much as possible
