dokku-nginx-override-by-app

This plugin makes it possible to customize the nginx configuration for an app that is based on an existing Docker image. This is the case if you create a new app with the Dokku git:from-image command.

For regular apps it's already possible to overwrite the nginx configuration by placing a nginx.conf.sigil file in the root of your code base, this won't work if you are using a third party image where you can't influence the code base. This is where this project comes in.

Installation

Like every Dokku plugin just run the following command:

dokku plugin:install https://github.com/dewey/dokku-nginx-override-by-app.git

Usage

1. With the dokku user navigate to /home/dokku, create a nginx.conf.sigil file there with the configuration you want to use and make sure it has the right permissions (chown dokku:dokku nginx.conf.sigil)
2. Use the app name and the path to the directory where you want to copy the config from to copy the config to the right directory: dokku nginx-override-by-app:add <app> /home/dokku/nginx.conf.sigil
3. Run dokku ps:rebuild <app> to rebuild your site with the new config
4. Done. Your app should now use your custom nginx.conf.sigil file.

If you ever want to tweak a config just navigate to /var/lib/dokku/data/nginx-override-by-app and you'll see all your configs there, in directories named after your apps.
