bundle_cache

bundle_cache

Speed up CI builds by caching rubygems bundle to Amazon S3.

Overview

When running a CI build, you have a clean system. That means that you have to install dependencies with bundler. It takes a lot of time and its very slow. Especially when you test suite runs for 20 seconds but bundle install runs for more than 2 minutes. Every single time.

bundle_chache is here to help. It uploads a bundle tarball to Amazon S3, so next time installation will be faster and consume less traffic. Double kill.

Example: 204.17 seconds bundle install reduced to 15.96 seconds

Build

Make sure you have Go 1.2 installed and GOPATH is set. Then run:

go get
go build bundle_cache.go
