这是我编写的代码的一个易于运行的版本,用于通过 client-go 进行端口转发。有硬编码的 pod 名称、命名空间和端口。你可以用你正在运行的那个来改变它们。
package main
import (
"flag"
"net/http"
"os"
"path/filepath"
"k8s.io/client-go/kubernetes"
"k8s.io/client-go/tools/clientcmd"
"k8s.io/client-go/tools/portforward"
"k8s.io/client-go/transport/spdy"
)
func main() {
stopCh := make(<-chan struct{})
readyCh := make(chan struct{})
var kubeconfig *string
if home := "/home/gianarb"; home != "" {
kubeconfig = flag.String("kubeconfig", filepath.Join(home, ".kube", "config"), "(optional) absolute path to the kubeconfig file")
} else {
kubeconfig = flag.String("kubeconfig", "", "absolute path to the kubeconfig file")
}
flag.Parse()
// use the current context in kubeconfig
config, err := clientcmd.BuildConfigFromFlags("", *kubeconfig)
if err != nil {
panic(err.Error())
}
// create the clientset
clientset, err := kubernetes.NewForConfig(config)
if err != nil {
panic(err.Error())
}
reqURL := clientset.RESTClient().Post().
Resource("pods").
Namespace("default").
Name("test").
SubResource("portforward").URL()
transport, upgrader, err := spdy.RoundTripperFor(config)
if err != nil {
panic(err)
}
dialer := spdy.NewDialer(upgrader, &http.Client{Transport: transport}, http.MethodPost, reqURL)
fw, err := portforward.New(dialer, []string{"9999:9999"}, stopCh, readyCh, os.Stdout, os.Stdout)
if err != nil {
panic(err)
}
if err := fw.ForwardPorts(); err != nil {
panic(err)
}
}
