应用Pod Network（calico）结尾为“无法识别..”“没有同类匹配项”

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kubernetes master，并收到成功消息“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Pod网络，因此我使用了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

然后我得到输出：

unable to recognize "https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/kubeadm/1.7/calico.yaml": no matches for kind "ConfigMap" in version "v1"

unable to recognize "https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/kubeadm/1.7/calico.yaml": no matches for kind "ServiceAccount" in version "v1"

我的kubectl版本输出为：

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

非常感谢您的帮助，甚至提供一些有关自调试的建议。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是否成功安装。

coredns和calico应该处于运行状态。

您必须按照post.中所述，为pod-network-cidr和apiserver-advertise-address使用单独的范围 请尝试删除群集，然后使用其他网络配置再次重新初始化它：

开始于：

  

运行此命令以还原通过“ kubeadm init”对该主机所做的任何更改，或者   “ kubeadm加入”。

kubeadm reset       

然后再次初始化群集（IP地址是一个安全的示例）。

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

此外，如果您按照在教程中所链接的主节点上的方式运行它，则可以跳过--apiserver-advertise-address，因为它使用当前计算机的默认网关。

从kubeadm documentation

中运行标准命令

  

要使kubectl适用于您的非root用户，请运行以下命令，   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

安装网络附加组件之后： 对于Calico：

  

为了使网络策略正常运行，您需要通过   --pod-network-cidr=192.168.0.0/16至kubeadm init。注意   印花布仅在amd64上工作。

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 您也可以从Kubernetes documentation官方网站开始重新安装kubeadm。
