Pakka helps you modularise and re-use packer templates. Dont repeat yourself.
Things you can do with pakka:
Re-use pre-existing open-source packer templates with your own infrastructure; Maintain libraries of provisioners/post-processors and apply them to multiple builds; Safely pull in changes from upstream without having to manually merge templates.
Make sure you have nodejs and packer installed, then run
npm install -g pakka
Write a Pakkafile in your packer template's directory and invoke
It will invoke packer to build the referenced templates, integrating all the transformations included in the pakkafile.
