如何从源代码安装kubelet，kubectl，kubeadm？

Question

因为我已经修改了k8s的源代码并想调试k8s，所以我想从源代码中构建和安装kubelet，kubectl，kubeadm。现在，我已经建立了kubelet, kubectl, kubeadm并获取了bin文件。当我想运行kubedam来部署集群时，我发现仅将它们复制到/usr/local/bin/对我不起作用，并且出现以下错误：

kubeadm init --apiserver-advertise-address=x.x.x.x --pod-network-cidr=10.244.0.0/16
W0204 20:55:28.785179    5682 configset.go:202] WARNING: kubeadm cannot validate component configs for API groups [kubelet.config.k8s.io kubeproxy.config.k8s.io]

有人可以帮助我如何从源代码正确安装kubelet, kubectl, kubeadm吗？

非常感谢。

如果您已经修改了kubernetes源代码以及如何测试这些更改，那么我建议遵循developer guide。使用kubeadm来测试修改后的kubernetes很难，因为kubeadm附带了正式发布的kubernetes，并且很难使其使用修改后的kubernetes。

如果您修改了kubeadm，并且想测试您可以遵循doc
