Question

我使用以下命令进行了kubeinit（我正在尝试在RHEL 7.6上设置Kubernetes）

kubeadm init --apiserver-advertise-address=15.217.230.99 --pod-network-cidr=15.232.10.195/27

我想使用印花布网络。由于我无法使用192.168.0.0/16网络，因此不得不从https://docs.projectcalico.org/v3.9/manifests/calico.yaml中获取calico.yaml，然后将CALICO_IPV4POOL_CIDR修改为值15.232.10.195/27（第一件事是，我不知道如果我在这里做的正确的话。我是Kubernetes的新手，正在尝试设置我的第一个集群）当我尝试使用命令（以sudo用户身份）应用文件时：

kubectl apply -f ./calico.yaml

我收到以下错误：

我的api服务器运行在端口6443上。这是我在kubeadm init生成的kubeadm连接令牌中看到的。

有人可以纠正我在哪里出错吗？除192.168.0.0/16外，还可以在印花布网络上使用其他任何面具吗？我无法使用它，因为它已在我们的网络中使用。

除了集群上的Linux节点外，我还想加入Windows节点。 Calico网络是正确的方法还是推荐？我想知道在初始化群集上的网络之前，我可以执行正确的操作

谢谢

在奋斗了几个小时之后，我发现kubectl apply命令需要以普通用户而不是root用户身份运行。确保您正在为我们在其中复制.kube / config文件的用户执行命令，否则它将不起作用之后，我看到我的主人已经准备好了。

请按照以下步骤解决此问题：

mkdir -p $HOME/.kube

sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

sudo chown $(id -u):$(id -g) $HOME/.kube/config

在Kubernetes集群上应用Calico网络时出错
