machineid

Overview ¶

Package machineid provides a way to get a unique identifier for the current machine without using any internal hardware IDs. As a result, it doesn't require any special permissions to run and works in unprivileged containers as well.

The returned ID is generally stable for the OS installation and usually stays the same after updates or hardware changes.

Caveat: Image-based environments usually have the same machine-id (perfect clones). Linux users can generate a new id with `dbus-uuidgen` and put the id into `/var/lib/dbus/machine-id` and `/etc/machine-id`.

Windows users can use the `sysprep` toolchain to create images, which produce valid images ready for distribution.

This is based on https://github.com/denisbrodbeck/machineid which is no longer maintained.

package main

import (
	"fmt"

	machineid "github.com/columnar-tech/machine-id"
)

func main() {
	id, err := machineid.ID()
	if err != nil {
		panic(err)
	}
	fmt.Println(id)
}

Output:
