A Cookiecutter (project template) for creating a barebone stacker project

Note:

You do not have to setup your project this way, this is just meant as a suggestion and some simple guidance to help folks who are new to stacker.

• Python 2.7 or 3.4+
• cookiecutter
• poetry

1. Generate a stacker project, following the prompts from the command.

   $ cookiecutter gh:cloudtools/stacker_cookiecutter
   project_name [myproject]:
   stacker_bucket [stacker-myproject]:
   repo_name [myproject]:
   description [stacker project for myproject]:

This command will create a new stacker project in your present working directory.

Note: You should try to make your stacker_bucket variable unique since S3 bucket names share a global namespace. It will default to stacker-{{ cookiecutter.project_name }} but you may choose any unique value.

In this example we have a product called myproduct and two environments called dev and prod.

Some notes about the files in this tree:

conf/<env>.env:

This is an "environment" file which holds variables that change in the config based on the environment. This allows you to have a single config for all your environments, while changing small things per environment.

See: http://stacker.readthedocs.io/en/latest/environments.html

stacker.yaml:

This is a "stacker config" file.

See: http://stacker.readthedocs.io/en/latest/config.html

blueprints/touch.py:

This is a tiny stacker blueprint that doesn't do much of anything. A blueprint is used to programatically generate CloudFormation JSON.

See: http://stacker.readthedocs.io/en/latest/blueprints.html

tests/blueprints/test_touch.py:

This is a tiny stacker blueprint test which only creates a simple resource in CloudFormation (a WaitCondition, which does nothing on it's own).

See: http://stacker.readthedocs.io/en/latest/blueprints.html#testing-blueprints

In this example we use a Makefile to save commands. The commands will be ran using poetry which will handle creating a virtualenv for you, as well as insuring that the correct packages are installed.

To execute stacker using your dev environment, using the --interactive flag run:

make dev ARGS=--interactive

To execute stacker using the prod environment, run:

make prod ARGS=--interactive
