Using pre-built releases

Using the packer init command

Starting from version 1.7, Packer supports a new packer init command allowing automatic installation of Packer plugins. Read the Packer documentation for more information.

To install this plugin, copy and paste this code into your Packer configuration . Then, run packer init.

packer {
  required_plugins {
    mondoo = {
      version = ">= 0.2.1"
      source  = ""

Manual installation

You can find pre-built binary releases of the plugin here. Once you have downloaded the latest archive corresponding to your target OS, uncompress it to retrieve the plugin binary file corresponding to your platform. To install the plugin, please follow the Packer documentation on installing a plugin.

Build from source

If you prefer to build the plugin from sources, clone the GitHub repository locally and run the command go build from the root directory. Upon successful compilation, a packer-plugin-mondoo plugin binary file can be found in the root directory. To install the compiled plugin, please follow the official Packer documentation on installing a plugin.
