Am I on a cloud, in a container, virtualized, or plain bare metal?

Build Status Go Report Card Go Reference


whatsthis is a Go-based CLI and library to determine where a system is running and what makes up the system.

To determine where a system is running, whatsthis will attempt to make a best-effort guess based on a variety of heuristics as to what container, virtualization, or cloud the system is running on. This is similar to an all-in-one collection of the systemd-detect-virt, virt-what, and cloud-id commands.

To summarize the system components, whatsthis will scan the filesystem for known files in /sys, /proc, or other directories. This data is then used to create a short summarize of the system in place of running several other commands (e.g. lsblk, ip, dmesg, dmidecode)


For complete details on how to install from binary, source, or from go, check out the install page for more information. This page also details the support for architectures and operating systems.

See the latest release page for the available binary downloads.


To get a full summary of the system run whatsthis and the output will show a breakdown module name by module name:

$ whatsthis
cloud: not detected
virt: not detected
container: not detected
distro: Ubuntu 20.10 (amd64)
kernel: 5.8.0-33-generic
bios: American Megatrends Inc. BIOS 3001 (12/04/2020)
cpu: AMD Ryzen 9 5950X 16-Core Processor with 16 cores (32 threads) on 1 socket
memory: 31.3G
    - enp6s0 24:4b:fe:9a:a4:fa 1000 mtu 9000 (igc)
    - virbr0-nic 52:54:00:6d:53:f1 mtu 1500
    - docker0 02:42:96:01:ec:70 mtu 1500
    - virbr0 52:54:00:6d:53:f1 mtu 1500
  nvme0n1 931.5G:
    - nvme0n1p1 512M EFI System Partition
    - nvme0n1p2 931G
  nvme1n1 1.9T:
    - nvme1n1p4 498M
    - nvme1n1p2 16M Microsoft reserved partition
    - nvme1n1p3 1.9T Basic data partition
    - nvme1n1p1 100M EFI system partition

To run only one particular module, run with only that module name:

$ whatsthis cpu
cpu: AMD Ryzen 9 5950X 16-Core Processor with 16 cores (32 threads) on 1 socket

Finally, to get the output in JSON add the --json flag:

$ whatsthis cpu --json
  "model": "AMD Ryzen 9 5950X 16-Core Processor",
  "numCore": 16,
  "numThread": 32,
  "numSocket": 1

See whatsthis help for a full list of modules and more information on options.


whatsthis offers several structs and functions to help determine the cloud, container, virtualization, and the underlying hardware of a system. Users can take advantage of these in their own code:

package main

import (


func main() {
  cloud, err := whatsthis.Cloud()
  if err != nil {
    fmt.Printf("Error getting cloud info: %v", err)

  if cloud.Detected {
