Intro

We need to create a temporary kubernetes cluster in github actions for running e2e tests in actions.

Installers comparison

• sealos:

  • Helm is not built in
  • Supports cluster image, it is very convenient to install helm, ingress, cert-manager, @see https://sealos.io
  • Containerd is used, and a dedicated version of the image is required to support docker, and docker will not be installed automatically
  • Large memory usage: 1750M - 500M = 1250M
  • Slower: 2m40s

• k3s

  • Built-in helm
  • High speed: <1m
  • Small memory footprint: 1200M - 500M = 700M

• kubekey

  • Need to manually install socat, conntrack, ebtables, ipset and other dependencies
  • Built-in helm
  • Friendly support for docker, automatic installation of docker
  • Slower: 2m20s
  • Small memory footprint: 1350M - 500M = 850M
