helm 默认使用 k8s集群的配置文件
When you create a cluster on GKE, it will give you credentials, including SSL certificates and certificate authorities. These need to be stored in a Kubernetes config file (Default: ~/.kube/config) so that kubectl and helm can access them.
##The Helm client learns about Kubernetes clusters by using files in the Kube config file format. By default, Helm attempts to find this file in the place where kubectl creates it ($HOME/.kube/config).
#Printing log messages for debugging the Kubernetes client can be enabled using the klog flags. Using the -v flag to set verbosity level will be enough for most cases.
helm list -v 6
# helm list 要加上 -n 指定命名空间
