Veewee-to-Packer

If you are or were a user of Veewee, then there is an official tool called veewee-to-packer that will convert your Veewee definition into an equivalent Packer template. Even if you're not a Veewee user, Veewee has a large library of templates that can be readily used with Packer by simply converting them.

Installation and Usage

Since Veewee itself is a Ruby project, so too is the veewee-to-packer application so that it can read the Veewee configurations. Install it using RubyGems:

$ gem install veewee-to-packer
...

Once installed, usage is easy! Just point veewee-to-packer at the definition.rb file of any template. The converter will output any warnings or messages about the conversion. The example below converts a CentOS template:

$ veewee-to-packer templates/CentOS-6.4/definition.rb
Success! Your Veewee definition was converted to a Packer
template! The template can be found in the `template.json` file
in the output directory: output

Please be sure to run `packer validate` against the new template
to verify settings are correct. Be sure to `cd` into the directory
first, since the template has relative paths that expect you to
use it from the same working directory.

Voila! By default, veewee-to-packer will output a template that contains a builder for both VirtualBox and VMware. You can use the -only flag on packer build to only build one of them. Otherwise you can use the --builder flag on veewee-to-packer to only output specific builder configurations.

Limitations

None, really. The tool will tell you if it can't convert a part of a template, and whether that is a critical error or just a warning. Most of Veewee's functions translate perfectly over to Packer. There are still a couple missing features in Packer, but they're minimal.

Bugs

If you find any bugs, please report them to the veewee-to-packer issue tracker. I haven't been able to exhaustively test every Veewee template, so there are certainly some edge cases out there.
