我试着大致了解Kubernetes 的艰难之路从头开始安装 Kubernetes。但我在装有 Amazon Linux 2023 的 AWS Graviton (Arm64) 节点上完成了此操作，主要使用 cloud-init。
我安装了列出的大部分依赖项引导 Kubernetes 工作节点来自亚马逊自己的存储库，其中包含 cloud-init 的这一部分。
#cloud-config
packages: ['runc', 'containerd', 'cni-plugins', 'socat', 'conntrack-tools', 'ipset']
但是该存储库不包含 Kubernetes 二进制文件，因此我将官方 Kubernetes Yum 存储库添加到 cloud-init 配置中。
yum_repos:
kubernetes:
baseurl: https://pkgs.k8s.io/core:/stable:/v1.28/rpm/
name: Kubernetes
gpgcheck: true
gpgkey: https://pkgs.k8s.io/core:/stable:/v1.28/rpm/repodata/repomd.xml.key
exclude: kubeadm cri-tools kubernetes-cni
然后，当我登录 VM 实例时，我尝试使用以下命令安装 Kubelet 二进制文件：
sudo dnf install kubelet
但是我收到错误（见下文），它依赖于kubernetes-cni。但是，这是我选择退出的，因为我使用的是cni-plugins来自 Amazon 存储库的二进制文件。据我所知，cni-plugins是 的替代 CNI 实现kubernetes-cni。Kubernetes The Hard Way 也做了同样的选择，使用cni-plugins而不是kubernetes-cni。
但是为什么我不能kubelet没有二进制文件就从 repo安装kubernetes-cni二进制文件？这只是 Kubernetes 方面缺少的配置，还是我误解了 Kubernetes The Hard Way 指南中关于工作节点需要哪些二进制文件的内容？

如果我从cloud-init 中删除kubernetes-cni该部分，并将其作为依赖项进行安装，则会收到冲突错误：exclude:kubeletkubernetes-cni
