heroku-deploy

It's better than git push

Introduction

TODO

I haven't written the introduction and proper usage stuff yet, sorry. I was roped into doing a presentation at Rails Meetup at the last minute, and I open sourced this thing quickly. So if you want to know more, poke @keithpitt on Twitter and Github!

Installation and Usage

You need the heroku-cli installed before you can use this plugin.

heroku plugins:install git://github.com/envato/heroku-deploy.git
heroku deploy

Because we don't do asset compliation on Heroku anymore, we can easily remove the asset group from being bundled, giving us a nice speed boost.

heroku config:add BUNDLE_WITHOUT="development:test:assets"

Migrations

By default any safe migrations will run without any downtime. So adding a new column/table/index. If a migration file contains an unsafe keyword remove_column, execute as examples, a maintenance page will be used for a downtime deploy. If you would like to prevent this behavior, then you can add a # safe comment on the destructive line. This allows a zero downtime deploy even with destructive operations.

Development

git clone git@github.com:envato/heroku-deploy.git

mkdir -p ~/.heroku/plugins
cd ~/.heroku/plugins
ln -s ~/path/to/heroku-deploy heroku-deploy

This should allow you to test the plugin and use it locally.

Testing

The tests can be run with rspec spec
