StackMaster::GpgParameterResolver

Resolve StackMaster parameters from within GPG encrypted YAML files.

Add this line to your application's Gemfile:

gem 'stack_master-gpg_parameter_resolver'

And then execute:

$ bundle

Or install it yourself as:

$ gem install stack_master-gpg_parameter_resolver

The secret parameters resolver expects a secret_file to be defined in the stack definition which is a GPG encrypted YAML file. Once decrypted and parsed, the value provided to the secret resolver is used to lookup the associated key in the secret file. A common use case for this is to store database passwords.

stack_master.yml:

stacks:
  us-east-1:
    my_app:
      template: my_app.json
      secret_file: production.yml.gpg

secrets/production.yml.gpg, when decrypted:

db_password: my-password

parameters/my_app.yml:

db_password:
  secret: db_password

After checking out the repo, run script/setup to install dependencies. You can also run script/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.
