# Vagrant Post-Processor

Type: `vagrant`

The Vagrant post-processor takes a build and converts the artifact
into a valid [Vagrant](http://www.vagrantup.com) box, if it can.
This lets you use Packer to automatically create arbitrarily complex
Vagrant boxes, and is in fact how the official boxes distributed by
Vagrant are created.

If you've never used a post-processor before, please read the
documentation on [using post-processors](/docs/templates/post-processors.html)
in templates. This knowledge will be expected for the remainder of
this document.

Because Vagrant boxes are [provider-specific](http://docs.vagrantup.com/v2/boxes/format.html),
the Vagrant post-processor is hardcoded to understand how to convert
the artifacts of certain builders into proper boxes for their
respective providers.

Currently, the Vagrant post-processor can create boxes for the following
providers.

* AWS
* DigitalOcean
* Hyper-V
* Parallels
* VirtualBox
* VMware

-> **Support for additional providers** is planned. If the
Vagrant post-processor doesn't support creating boxes for a provider you
care about, please help by contributing to Packer and adding support for it.

## Configuration

The simplest way to use the post-processor is to just enable it. No
configuration is required by default. This will mostly do what you expect
and will build functioning boxes for many of the built-in builders of
Packer.

However, if you want to configure things a bit more, the post-processor
does expose some configuration options. The available options are listed
below, with more details about certain options in following sections.

* `compression_level` (integer) - An integer repesenting the
  compression level to use when creating the Vagrant box.  Valid
  values range from 0 to 9, with 0 being no compression and 9 being
  the best compression. By default, compression is enabled at level 6.

* `include` (array of strings) - Paths to files to include in the
  Vagrant box. These files will each be copied into the top level directory
  of the Vagrant box (regardless of their paths). They can then be used
  from the Vagrantfile.

* `keep_input_artifact` (boolean) - If set to true, do not delete the
  `output_directory` on a successful build. Defaults to false.

* `output` (string) - The full path to the box file that will be created
  by this post-processor. This is a
  [configuration template](/docs/templates/configuration-templates.html).
  The variable `Provider` is replaced by the Vagrant provider the box is for.
  The variable `ArtifactId` is replaced by the ID of the input artifact.
  The variable `BuildName` is replaced with the name of the build.
  By default, the value of this config is `packer_{{.BuildName}}_{{.Provider}}.box`.

* `vagrantfile_template` (string) - Path to a template to use for the
  Vagrantfile that is packaged with the box.

## Provider-Specific Overrides

If you have a Packer template with multiple builder types within it,
you may want to configure the box creation for each type a little differently.
For example, the contents of the Vagrantfile for a Vagrant box for AWS might
be different from the contents of the Vagrantfile you want for VMware.
The post-processor lets you do this.

Specify overrides within the `override` configuration by provider name:

```javascript
{
  "type": "vagrant",
  "compression_level": 1,
  "override": {
    "vmware": {
      "compression_level": 0
    }
  }
}
```

In the example above, the compression level will be set to 1 except for
VMware, where it will be set to 0.

The available provider names are: `aws`, `digitalocean`, `virtualbox`,
`vmware`, and `parallels`.

## Input Artifacts

By default, Packer will delete the original input artifact, assuming
you only want the final Vagrant box as the result. If you wish to keep the
input artifact (the raw virtual machine, for example), then you must
configure Packer to keep it.

Please see the [documentation on input artifacts](/docs/templates/post-processors.html#toc_2)
for more information.
