What is AutoK3s

English / 简体中文

K3s is a fully certified Kubernetes offering, it can replace the "full-fat" K8s in some cases.

AutoK3s is a lightweight tool for simplifying the cluster management of K3s, it can help you Run K3s Everywhere.

Key Features

  • Shorter provisioning time with API, CLI and UI dashboard.
  • Cloud provider Integration(simplifies the setup process of CCM on cloud providers).
  • Flexible installation options, like K3s cluster HA and datastore(embedded etcd, RDS, SQLite, etc.).
  • Low cost(try spot instances in each cloud).
  • Simplify operations by UI dashboard.
  • Portability between clouds by leveraging tools like backup-restore-operator.
  • Airgap K3s package management and installation.
  • SSH Key Management can manage the SSH keys are used to provision K3s clusters.

Providers

Now supports the following providers, we encourage submitting PR contribution for more providers:

  • aws - Bootstrap K3s onto Amazon EC2
  • google - Bootstrap K3s onto Google Compute Engine
  • alibaba - Bootstrap K3s onto Alibaba ECS
  • tencent - Bootstrap K3s onto Tencent CVM
  • k3d - Bootstrap K3d onto Local Machine
  • native - Bootstrap K3s onto any VM

Quick Start (tl;dr)

Scenario 1 - Run with docker:

# The commands will start autok3s daemon with an interactionable UI.
# Standard Linux (Recommended)
$ docker run -itd --restart=unless-stopped --net=host -v /var/run/docker.sock:/var/run/docker.sock cnrancher/autok3s:v0.7.0

# MacOS
$ docker run -itd --restart=unless-stopped -p 8080:8080 -v /var/run/docker.sock:/var/run/docker.sock -e DOCKER_HOST="" cnrancher/autok3s:v0.7.0

Scenario 2 - Run with docker-compose

# AutoK3s is available at: http://autok3s.vcap.me (vcap.me resolves to 127.0.0.1).
# The cli and container uses the same `AUTOK3S_CONFIG` directory.
docker-compose up -d

Scenario 3 - Run with cli:

# The commands use the shell script on MacOS and Linux, or visit the Releases page to download the executable for Windows.
curl -sS https://rancher-mirror.rancher.cn/autok3s/install.sh  | sh
