My notes for Dokku on Digital Ocean.

These may be a bit outdated: Since I originally wrote them, I've reinstalled on a newer Dokku and may not have updated every section below.

Commands

Install dokku-cli (gem install dokku-cli) for a more Heroku-like CLI experience (dokku config:set FOO=bar).

# List/run commands when not on Dokku server (assuming a "henroku" ~/.ssh/config alias)

ssh henroku dokku

Integrating TinyMCE in an ember-cli app

TinyMCE is a javascript WYSIWYG editor that is highly configurable and has a ton of features and plugins. It integrates with jQuery and, with a bit of work, it can be integrated in your ember-cli app.

Step 1: Install TinyMCE:

bower install --save tinymce

Step 2: Import the required files into your app via broccoli. In order to do that you will need a plugin called broccoli-static-compiler:

Download and Install Postgres.app

Before we can setup PostGIS we need to have a local version of Postgresql installed and running. The most effecient way to do this is to download and install Postgres.app.

Spatially Enable your Postgres Database

Once Postgres.app is installed in your computers /Applications directory. Open the Terminal and enter the following two commands

psql -d DATABASE_NAME -f /Applications/Postgres.app/Contents/Versions/9.3/share/postgresql/contrib/postgis-2.1/postgis.sql
