k3s执行helm命令报错Error Kubernetes cluster unreachable Get “httplocalhost8080versiontimeout=32s“

k3s执行helm命令报错:Error: Kubernetes cluster unreachable: Get “http://localhost:8080/version?timeout=32s“

报错信息:

Error: Kubernetes cluster unreachable: Get "http://localhost:8080/version?timeout=32s": dial tcp [::1]:8080: connect: connection refused

报错原因: helm v3版本不再需要Tiller，而是直接访问ApiServer来与k8s交互，通过环境变量KUBECONFIG来读取存有ApiServre的地址与token的配置文件地址，默认地址为~/.kube/config

解决方法:

手动配置 KUBECONFIG环境变量

临时解决:

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

永久解决:

执行: vi /etc/profile
写入内容: export KUBECONFIG=/etc/rancher/k3s/k3s.yaml
执行: source /etc/profile
