clouddetect

A Go library to detect the cloud service provider of a host.

This library is the Go version of my Rust crate cloud-detect, which in itself is inspired by the Python-based cloud-detect and the Go-based satellite modules.

Like these modules, clouddetect uses a combination of checking vendor files and metadata endpoints to accurately determine the cloud provider of a host.

While this library is structured similarly to the Rust crate, it follows Go conventions and idioms and is not a direct port.

Features

• Currently, this module supports the identification of the following providers:
  • Akamai Cloud (akamai)
  • Amazon Web Services (aws)
  • Microsoft Azure (azure)
  • Google Cloud Platform (gcp)
  • Alibaba Cloud (alibaba)
  • OpenStack (openstack)
  • DigitalOcean (digitalocean)
  • Oracle Cloud Infrastructure (oci)
  • Vultr (vultr)
• Fast, simple and extensible.
• Real-time console logging using the zap module.

Usage

Add the library to your project by running:

go get github.com/nikhil-prabhu/clouddetect/v2@latest

Detect the cloud provider and print the result (with default timeout).

package main

import (
 "fmt"

 "github.com/nikhil-prabhu/clouddetect/v2"
)

func main() {
 provider := clouddetect.Detect()

 // When tested on AWS:
 fmt.Println(provider) // "aws"

 // When tested on local/non-supported cloud environment:
 fmt.Println(provider) // "unknown"
}

Detect the cloud provider and print the result (with custom timeout and logging).

package main

import (
 "fmt"

 "github.com/nikhil-prabhu/clouddetect/v2"
 "go.uber.org/zap"
)

func main() {
 // Use zap.NewDevelopment() for development mode
 logger := zap.Must(zap.NewProduction())
 defer logger.Sync()

 provider := clouddetect.Detect(
  clouddetect.WithTimeout(10),
  clouddetect.WithLogger(logger),
 )

 // When tested on AWS:
 fmt.Println(provider) // "aws"

 // When tested on local/non-supported cloud environment:
 fmt.Println(provider) // "unknown"
}

You can also check the list of currently supported cloud providers.

package main

import (
 "fmt"

 "github.com/nikhil-prabhu/clouddetect/v2"
)

func main() {
 fmt.Println(clouddetect.SupportedProviders)
}
