dokku-app-configfiles

dokku-app-configfiles is a plugin that allows dokku app config files (such as VHOST, ENV, DOCKER_OPTIONS (for the dokku-docker-options plugin), nginx.tpl or nginx.ssl.tpl (for the dokku-nginx-alt plugin), etc. to be taken from the app's git repository. This eliminates the need to manually create these files on the dokku server.

In short, per-app dokku config files are checked into the app's git repository under the directory .dokku/. Upon git push to the dokku server, any files in .dokku/* are copied to /home/dokku/[app name]/.

Why would I use this?

Although it is prudent to always keep server configuration files separate from app files, many cloud hosts (such as dotcloud) offer the option to supply custom ngnix and other configuration files by checking them into your app's root directory. This approach is simple, and an advantage is that these configuration files are always backed up with the app. This plugin enables similar functionality for dokku.

Installation and Usage

1. Install the plugin by cloning into the dokku plugins directory:

   git clone https://github.com/mikexstudios/dokku-app-configfiles.git /var/lib/dokku/plugins/app-configfiles

2. In your app's git repository (this is the app that you intend to push to dokku), create a folder called .dokku. For example, if my app was in a folder called my-webapp/, the folder would be created at my-webapp/.dokku/.

   cd my-webapp/ #this is the app you want to git push to dokku
   mkdir .dokku

3. Inside the .dokku/ folder, place your dokku config files. For example, let's create some fixed environment variables:

   cd my-webapp/.dokku/ 
   echo "export HELLO='world'" > ENV

   NOTE: In practice, you may not want to check sensitive environment variables (such as API keys) into your git repository if it is publically accessible.

4. Add the .dokku/ directory to your app's git repository:

   cd my-webapp/ #this is the app you want to git push to dokku
   git add .dokku/
   git commit -m 'Added dokku config files.'

5. Push your app to dokku and the config files in .dokku/* should be copied to your app's directory (e.g. /home/dokku/my-webapp/) on the dokku server.
