Templating wrapper for docker-compose

Project Description

# meta-compose

This package aims to solve the problem of variable substitution in
docker-compose files by parsing them as [Jinja2](

It was inspired by the discussion

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

## Quickstart:

- Install with `pip install meta-compose`

- Create a file `meta-compose.yml` that is a [Jinja2](
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

## Usage

usage: meta-compose [-h] [-d DATAFILE] [-t TEMPLATE] [-o OUTPUTFILE]

optional arguments:
-h, --help show this help message and exit
-d DATAFILE, --datafile DATAFILE
Use to specify data files in addition to meta-compose-
data.yml. They must be JSON or YAML files.
-t TEMPLATE, --template TEMPLATE
Use to specify the template file to use. Defaults to
Use to specify the output file to create. Defaults to

## Syntax of meta-compose.yml

- Everything in basic [Jinja2]( 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.
