无法在 ubuntu 18.04 上运行 k3s 服务器

无法在 ubuntu 18.04 上运行 k3s 服务器

我在 Ubuntu 18.04 上安装 K3S 如下:

curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
kubectl version --client
curl -sfL https://get.k3s.io | sh -
sudo kubectl get nodes

但是,当我这样做时sudo kubectl get nodes,出现以下错误

ubuntu@ip-10-0-0-62:~$ sudo kubectl get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?

我检查了三个重要端口的正在运行的进程

ubuntu@ip-10-0-0-62:~$ sudo lsof -i:6443

不确定问题是什么以及如何解决它。

答案1

您可能需要检查您的.kube/config。您的错误消息表明 kubectl 尝试连接到,localhost:8080但您的lsof调用表明您希望通信发生在端口 6443 上。请特别检查clusterskubectl 配置中的部分。它可能是错误的活动上下文或错误的服务器 URL。
