docker - 在 Docker 容器内 Kubectl 给出 Unable to connect to the server: dial tcp i/o timeout

Question

我正在尝试遵循本教程https://www.youtube.com/watch?v=9EUyMjR6jSc。我正在使用 Ubuntu 20.04LTS，我安装了 k3d，这是 ~/.kube/config 信息

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: ...
    server: https://192.168.0.13:16443
  name: k3d-dev
contexts:
- context:
    cluster: k3d-dev
    user: admin@k3d-dev
  name: k3d-dev
current-context: k3d-dev
kind: Config
preferences: {}
users:
- name: admin@k3d-dev
  user:
    client-certificate-data:...
    client-key-data:...

Docker 版本是 Version: 20.10.2. 根据教程，我需要运行一个 halyard 容器，并且在容器内我可以访问本地 kubernetes（在本例中为 k3d）。halyard 容器带有 kubectl，所以我只需要使用上述信息创建一个 ~/.kube/config，但我仍然收到 Unable to connect to server 消息。如果我运行 kubectl cluster-info，集群就会启动并运行

Kubernetes control plane is running at https://192.168.0.13:16443
CoreDNS is running at https://192.168.0.13:16443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
Metrics-server is running at https://192.168.0.13:16443/api/v1/namespaces/kube-system/services/https:metrics-server:/proxy

在升降索容器内

bash-5.0$ kubectl version
