cloudsysfs

Detect Cloud Provider from DMI data on the local sysfs (/sys) filesystem

Usage

package main

import (
  "fmt"

  "github.com/erichs/cloudsysfs"
)

func main() {
  switch cloudsysfs.Detect() {
  case "aws":
    fmt.Println("Amazon Web Services")
  case "azure":
    fmt.Println("Microsofte Azure")
  case "digitalocean":
    fmt.Println("Digital Ocean")
  case "gce":
    fmt.Println("Google Compute Engine")
  case "openstack":
    fmt.Println("OpenStack")
  default:
    fmt.Println("No cloud detected")
  }
}

Motivation

Inspired by cloudid, I wanted a simple and fast mechanism for determining if the local environment is a cloud I want to support. cloudid is great, but takes the (admittedly more robust) approach of fingerprinting metadata signatures from APIPA HTTP API endpoints (http://169.254.x.x/latest/metadata and friends).

This library takes the approach of attempting to read from the local sysfs filesystem, looking for unambiguous vendor or product files that identify the cloud provider. The /sys filesystem is provided by the Linux kernel, so only Linux is currently supported.

Supported Operating Systems
