为什么Kubectl与sudo会有不同的行为? [英] Why does kubectl have different behavior with sudo?

问题描述

使用sudo运行kubectl get pods:

sudo kubectl get pods
The connection to the server localhost:8080 was refused - did you specify the right host or port?

以普通用户身份运行:

kubectl get pods
No resources found.

推荐答案

默认情况下，kubectl在〜/.kube/config(或指向$ KUBECONFIG的文件)中查找以确定要连接的服务器.以超级用户身份运行命令时，您的主目录和环境是不同的.当找不到连接信息时，kubectl默认为localhost:8080

By default, kubectl looks in ~/.kube/config (or the file pointed to be $KUBECONFIG) to determine what server to connect to. Your home directory and environment are different when running commands as root. When no connection info is found, kubectl defaults to localhost:8080
