IndieHosters applications

What is an application for IndieHosters? It is a repo that must contain the following:

• docker-compose.yml
• an optionnal scripts folder with:
• an install script
• a pre-backup script to do databases dump for instance

Docker-compose

The docker-compose must start a service called web that exposes a port 80. Under the web service, it should have the environment variable ready to be populated:

...
  environment:
    - VIRTUAL_HOST
...

Dockerfile

The docker-compose should use Docker official images. If none are available, then make one, and try to pull request upstream and offer help to make it official. If you need more than the bare image, base your Dockerfile on the official one, and try to pull request the official one. Other people might need your work.

Environment

Mail

If the application needs to send email pass the mail server configuration as environment variables:

MAIL_HOST
MAIL_PORT
MAIL_USER
MAIL_PASS

Your app should be able to understand them.

Example

A good example is the wordpress application.
