Engine Yard Cloud Quick Deploy

This is a bash script for doing super quick deploys on Engine Yard Cloud. Perfect for when you just need to fix a quick typo. Deploys quick changes to a single app server in typically <~2s.

Install

Run this:

mkdir -p ~/bin && curl https://raw.github.com/gist/1872050/086475dcbc8e7d92d55ce0757d3692d77793f4b1/ey_deploy.sh > ~/bin/ey_deploy && chmod +x ~/bin/ey_deploy

Then create a .ey file in your project root directory. See .ey-example

How to use it

Deploy changes (using rsync):

ey_deploy

Deploy changes with migrations:

ey_deploy -m

Deploy changes and run asset precompilation:

ey_deploy -p

Deploy changes and clear the page cache:

ey_deploy -c

What does it do?

All this does is rsyncs your local code to your Engine Yard Cloud servers. It doesn't do any sanity checks or anything, so you'll still want to run ey deploy once in a while. But for day to day deploying, you won't get much faster than this.

.ey-example
content_copyfile_download
# Place this file in the root of your project directory

# eg. APPNAME=tito
APPNAME=

# eg. APP_SERVERS=(deploy@app1.tito.io deploy@app2.tito.io)
APP_SERVERS=()

# eg. CACHE_DIRS=(public/cache)
CACHE_DIRS=()
