The configuration or file you are setting up the client from likely contains a null character at the end of the server url line which is getting picked up as part of the base URL

/kind support

/kind support

Use clientcmd.BuildConfigFromFlags("", "") to build the client configuration. This should not cause problems with %00 (NULL characters) in URLs. And the problem occurs randomly.

code： clientConfig, err := clientcmd.BuildConfigFromFlags("", "") if err != nil { return nil, err } clientConfig.ContentType = "application/vnd.kubernetes.protobuf" clientset, err := kubernetes.NewForConfig(clientConfig) if err != nil { return nil, err }
