卸载

如果你使用install.sh脚本安装了 K3s，那么在安装过程中会生成一个卸载脚本。该脚本在您的节点上的/usr/local/bin/k3s-uninstall.sh上创建（或者是k3s-agent-uninstall.sh）。

/usr/local/bin/k3s-uninstall.sh

/usr/local/bin/k3s-agent-uninstall.sh

安装工作节点

获取token

cat /var/lib/rancher/k3s/server/node-token 

curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn INSTALL_K3S_VERSION=v1.28.14+k3s1 K3S_URL=https://myserver:6443 K3S_TOKEN={mynodetoken} sh -s - --docker

Docker加速

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://docker.1ms.run"]
}
