在此之前不需要部署k3s server 也不需要部署containerd。
部署格式
curl -sfL https://docs.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn K3S_URL=https://主节点IP地址:6443 K3S_TOKEN=主节点的token sh -k3s-agent安装
由于 rancher.cn 域名正在备案中，因此使用默认的 https://rancher-mirror.rancher.cn/k3s/k3s-install.sh 地址部署集群会出现部署失败情况。如果发生此类问题，请使用以下方式解决： --k3s-install-script=https://rancher-mirror.rancher.cn/k3s/k3s-install.sh。
