‘os’ package of golang provides a Hostname function that can be used to get the hostname that is reported by the kernel
Below is the signature of this method. It returns an error if not able to successfully get the hostname

func Hostname() (name string, err error)

Let’s see a working code

Code

package main

import (
	"fmt"
	"os"
)

func main() {
	hostname, err := os.Hostname()
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}
	fmt.Printf("Hostname: %s", hostname)
}

Output:

Hostname:
