# Vagrant Post-Processor

Type: `vagrant`

The Packer Vagrant post-processor takes a build and converts the artifact into a
valid [Vagrant](https://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](https://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
-   Azure
-   DigitalOcean
-   Azure
-   Hyper-V
-   LXC
-   Parallels
-   QEMU
-   VirtualBox
-   VMware
-   Docker

-&gt; **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` (number) - An integer representing 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/engine.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:

``` json
{
  "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`
- `azure`
- `digitalocean`
- `google`
- `hyperv`
- `parallels`
- `libvirt`
- `lxc`
- `scaleway`
- `virtualbox`
- `vmware`
- `docker`

## 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.

### Docker

Using a Docker input artifact will include a reference to the image in the
`Vagrantfile`. If the image tag is not specified in the post-processor, the
sha256 hash will be used.

The following Docker input artifacts are supported:

 - `docker` builder with `commit: true`, always uses the sha256 hash
 - `docker-import`
 - `docker-tag`
 - `docker-push`
