我是kubernetes的新手，正在尝试在本地机器上设置一个运行cassandra的集群。我用kind创建了一个成功的集群。在那之后当我试着跑的时候 kubectl cluster-info ，我得到以下错误： Unable to connect to the server: dial tcp 127.0.0.1:45451: connectex: No connection could be made because the target machine actively refused it. 在 docker container ls ，我可以看到控制平面在使用端口的容器上运行，如下所示：

CONTAINER ID        IMAGE                  COMMAND                  CREATED             STATUS              PORTS                       NAMES
1c4b6101b8ff        kindest/node:v1.18.2   "/usr/local/bin/entr"   3 hours ago         Up 2 hours          127.0.0.1:45451->6443/tcp   kind-cassandra-control-plane
625fee22e0e6        kindest/node:v1.18.2   "/usr/local/bin/entr"   3 hours ago         Up 2 hours                                      kind-cassandra-worker

我可以通过执行 kubectl config view 如下所示，确认kubectl能够读取正确的配置文件：

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://127.0.0.1:45451
  name: kind-kind-cassandra
contexts:
- context:
    cluster: kind-kind-cassandra
    user: kind-kind-cassandra
  name: kind-kind-cassandra
current-context: kind-kind-cassandra
kind: Config
preferences: {}
users:
- name: kind-kind-cassandra
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED

更新：
当我跑的时候 netstat ，我可以看到下面127.0.0.1上的活动连接
