哪种格式的kubeadm init --token是正确的?
(2/4) Initializing your master显示" - 令牌xyz"。
kubeadm join --token <token> <master-ip>:<master-port> --discovery-token-ca-cert-hash sha256:<hash>
kubeadm init显示&#34; - 令牌= xyz&#34;。
kubeadm join --token=abcdef.1234567890abcdef --discovery-token-ca-cert-hash sha256:1234..cdef 192.168.1.1:6443
执行日志(使用Ansible)显示了几条错误消息。不知道这是否与格式有关。

kubeadm
使用spf13/pflag,其中两种表示法都是正确的。
来自docs:
--flag // boolean flags, or flags with no option default values
--flag x // only on flags without a default value
--flag=x

据我所知,格式并不重要。它的输出是推荐的
You can now join any number of machines by running the following on each node
as root:
kubeadm join --token <token> <master-ip>:<master-port> --discovery-token-ca-cert-hash sha256:<hash>
我认为Token用于安全性(ssl或tls)目的,因此主节点和工作节点可以使用加密进行通信。它是TLS Handshake的一部分。
由于工作节点中的Kubelet需要自己的令牌与主节点上的kube-api服务器通信。
