v1.0.0

v1.0.0

After over a year since its initial conception, we are proud to announce that K3s has reached v1.0.0. This release denotes a focus on stability and quality moving forward, while still delivering new and useful features.

K3s is a fully conformant Kubernetes distribution that focuses on presenting a small footprint and ease of operation. K3s packages the entire Kubernetes stack into a single binary, including:

• Kubernetes master components: kube-apiserver, kube-scheduler, kube-controller-manager, and cloud-controller-manager
• Kubernetes node components: kubelet and kube-proxy
• containerd as the container runtime
• CoreDNS for cluster DNS
• Flannel for cluster networking
• CLI utilities including kubectl, crictl, and ctr
• An embedded SQLite database that replaces etcd

K3s also packages features that deliver value beyond the baseline Kubernetes stack, including:

• The Traefik ingress-controller
• A service load balancer implementation backed by Traefik
• Our local path provisioner storage driver
• Our novel Kubernetes datastore interface KINE that allows you to choose a datastore backend that best fits your use case, including: SQLite, DQLite, MySQL, Postgres, and etcd.
• Our helm-controller that provides a CRD and controller paradigm for managing helm charts
• Encrypted networking backed IPSec or Wireguard

This is all brought to you in a single binary that is less than 50 MB and runs on amd64, arm64, and armhf architectures.
