A gem to install and interface with HashiCorp's Packer utility
Add this line to your application's Gemfile:
gem 'packer-binary'
And then execute:
$ bundle
Or install it yourself as:
$ gem install packer-binary
You need to specify which version of HashiCorp Packer to use. You can also specify where to save the binary file.
require 'packer/binary'
Packer::Binary.configure do |config|
config.version = '1.0.4'
config.download_path = '/tmp'
end
The {Packer::Binary} module will automagically map method calls to packer commands. This serves to better support future versions of packer and potentially new commands. For example, the equivalent of packer build test.json in Ruby:
Packer::Binary.build('test.json')
If you call a method not supported by the packer binary, you will get a {Packer::Binary::Command::CommandFailure} exception.
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
