# Usage: cached-bundle install --deployment
|
|
#
|
|
# After running `bundle`, caches the `./bundle` directory to S3.
|
|
# On the next run, restores the cached directory before running `bundle`.
|
|
# When `Gemfile` changes, the cache gets rebuilt.
|
|
#
|
|
# Requirements:
|
|
# - Gemfile
|
|
# - TRAVIS_REPO_SLUG
|
|
# - TRAVIS_RUBY_VERSION
|
|
# - AMAZON_S3_BUCKET
|
|
# - script/s3-put
|
|
# - bundle
|
|
# - curl
