multi-start 1.1.0

Run multiple services inside a docker container

multi-start

This tool aims to help running multiple services inside a single docker container.

Sometimes you might want to have backend, frontend and nginx (or a combination of those) inside a single container. This tool may help with:

• Prepare final Nginx configs using parse-template
• Wait until backend and frontend start responding before running Nginx
• Stop every process if one of them exits so the whole container stops gracefully

Installation

pip install multi-start
