应用 pod network (calico) 以“无法识别..”“没有匹配的种类”结尾

Question

我正在尝试在 ubuntu 上构建本地裸机 kubernetes 集群。

按照分步指南（https://www.youtube.com/watch?v=UWg3ORRRF60）我已经成功安装了 kubernetes master 并收到了成功消息“您的 Kubernetes master 已成功初始化！” 使用 'kubeadm init --pod-network-cidr=10.0.0.0/16 --apiserver-advertise-address=10.0.0.20' 命令初始化集群后。

现在下一步是部署一个 pod 网络，所以我使用了 calico，运行以下命令：

kubectl apply -f https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/kubeadm/1.7/calico.yaml --validate=false

我得到输出：

我的 kubectl 版本输出是：

Client Version: version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.1", GitCommit:"b1b29978270dc22fecc592ac55d903350454310a", GitTreeState:"clean", BuildDate:"2018-07-17T18:53:20Z", GoVersion:"go1.10.3", Compiler:"gc", Platform:"linux/amd64"}
Error from server (NotFound): the server could not find the requested resource

将不胜感激任何帮助，甚至一些自我调试的建议。谢谢。

如果 kubernete 版本高于 1.16，请使用以下链接安装 calico。

kubectl apply -f https://docs.projectcalico.org/v3.9/manifests/calico.yaml

请检查节点状态以确认 calico 是否安装成功。

coredns 和 calico 应该处于运行状态。

正如本文所述，您必须为 pod-network-cidr 和 apiserver-advertise-address 使用不同的范围。 请尝试删除集群并使用不同的网络配置重新启动它：

从...开始：

运行此命令以还原“kubeadm init”或“kubeadm join”对此主机所做的任何更改。

kubeadm reset       

然后再次初始化集群（IP 地址是一个安全的例子）。

kubeadm init --pod-network-cidr=192.168.0.0/16 --apiserver-advertise-address=10.0.0.20 

此外，如果您像在主节点上链接的教程中那样运行它，您可以跳过 --apiserver-advertise-address 因为它使用当前机器的默认网关。

运行 kubeadm文档中的标准命令

要使 kubectl 为您的非 root 用户工作，请运行这些命令，它们也是kubeadm init 输出的一部分 ：

mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config

或者，如果您是 root 用户，则可以运行：

export KUBECONFIG=/etc/kubernetes/admin.conf

之后安装网络附加组件： 对于Calico：

为了使网络策略正常工作，您需要传递 --pod-network-cidr=192.168.0.0/16 给 kubeadm init. 请注意，Calicoamd64 仅适用于 。

kubectl apply -f https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/rbac-kdd.yaml kubectl apply -f https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml 您还可以从Kubernetes官方文档开始，了解如何安装 kubeadm。
