meta-compose 0.1.1

# meta-compose

This package aims to solve the problem of variable substitution in docker-compose files by parsing them as [Jinja2](http://jinja.pocoo.org/) template.

It was inspired by the discussion [here](https://github.com/docker/compose/issues/1377)

It supports variable declaration in a separate YAML file as well as access to environment variables.

## Usage:

• Install with pip install meta-compose

• Create a file meta-compose.yml that is a [Jinja2](http://jinja.pocoo.org/) template for a docker compose file.

• [Optional] Create a file meta-compose-data.yml that contains the variables used in the template that are not environment variables.

• Call meta-compose and it will create a docker-compose.yml in the current directory

## Syntax of meta-compose.yml

• Everything in basic [Jinja2](http://jinja.pocoo.org/) is allowed.

• To access environment variables use {{‘default’| env(‘VARIABLE_NAME’)}} where VARIABLE_NAME is the name of your environment variable and default is the default value you want it to be if the environment variable is not set.
