docker-composition 1.0.5

Docker-compose package manager

Description

Still very much in alpha. But a package manager similar to that of helm but for docker-compose applications.
Handles sub-applications and values.yaml files with templates similar to that used for kubernetes.yaml files.

To start you need three files (see examples here: https://github.com/sam-technesci/composer/tree/main/examples):
app.yaml
template.yaml
values.yaml
The templating language used is Jinja2 and you substitute variables from your values.yaml(s) into the template.

Quick install

cd examples/basic_application && composer install
See the README.md at examples/basic_application/README.md for a walk-through.
Defaults to using values.yaml in the same directory.
To view your template before installing it you can do composer template or you can save a template with composer template > docker-compose.yaml
For more commands do: composer --help
