Feature: Grab CloudFormation Templates from S3 Bucket

[pbnj]

Feature

As a developer, I'd like to specify a CloudFormation template in my parameter.yml file. Restacker CLI should be able to parse the parameter.yml file, find the CFNTemplate: configuration, and automatically grab the matching CFn template from S3 Bucket supplied in restacker.yml file.

Example

# .restacker/restacker.yml
...
:ctrl:
  :label: control_account
  :account_number: '123456789012'
  :role_name: xyz
  :role_prefix: "/role/prefix/"
  :bucket:
    :name: my-bucket
    :prefix: "path/to/templates"

# parameter.yml
...
CFNTemplate: webapp
...

# s3://my-bucket/path/to/templates/
- webapp.json
- single_instance_no_elb.json
...

TODO

• Publish a set of generic Cloud Formation templates in restacker repo.
