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
