如何在Golang中部署Kubernetes微服务

package main
<p>import (
"net/http"
"os"
)</p><p>func main() {
http.HandleFunc("/healthz", func(w http.ResponseWriter, r *http.Request) {
w.WriteHeader(http.StatusOK)
w.Write([]byte("OK"))
})</p><pre class="brush:php;toolbar:false;"><pre class="brush:php;toolbar:false;">port := os.Getenv("PORT")
if port == "" {
    port = "8080"
}

http.ListenAndServe(":"+port, nil)
