How to authorize a web-socket connection in kubernetes in Go? - go

Question

so I am trying to implement Use a WebSocket client to exec commands in a Kubernetes pod in Go (so I create a WebSocket app to remotely run commands in a container's pod for debugging/monitoring/code-practice) but I am getting:
dial:tls: first record does not look like a TLS handshake exit status
1
What am I missing? I am using this as an example cluster. There is a way to do it by passing a bearer token but that doesn't look very safe.
package main
import (
"io/ioutil"
"log"
"github.com/gorilla/websocket"
)
func main() {
ca, err := ioutil.ReadFile("/home/george/.minikube/ca.crt")
if err != nil {
log.Fatal(err)
}
// read client cert
clientCert, err := ioutil.ReadFile("/home/george/.minikube/profiles/minikube/client.crt")
if err != nil {
log.Fatal("Error loading client cert", err)
}
// read client key
clientKey, err := ioutil.ReadFile("/home/george/.minikube/profiles/minikube/client.key")
if err != nil {
log.Fatal("Error loading client key", err)
}
value1 := "ca:" + string(ca)
value2 := "cert: " + string(clientCert)
value3 := "key: " + string(clientKey)
dialer := websocket.DefaultDialer // use default dialer
dialer.Subprotocols = []string{value1, value2, value3}
//dialer.TLSClientConfig = &tls.Config{InsecureSkipVerify: true}
url := "wss://192.168.49.2:30110/api/v1/namespaces/default/pods/hello-minikube-6ddfcc9757-g4484/exec?command=echo&command=ls&stderr=true&stdout=true"
//dial websocket
c, _, err := dialer.Dial(url, nil)
if err != nil {
// print response body
//fmt.Println(response.Body)
log.Fatal("dial:", err)
}
// receive websocket message
defer c.Close()
}
