samewave / heroku-buildpack-upload-static-assets-to-s3

Uploads static assets to S3 when deploying to heroku

Purpose

Uploads static assets to S3 when deploying to heroku. Requires NodeJS to be installed when building.

Setting Mandatory Environment Variables for build

AWS_ACCESS_KEY_ID=<aws access key id>
AWS_SECRET_ACCESS_KEY=<aws secret access key>
AWS_DEFAULT_REGION=<aws-region>
AWS_STATIC_BUCKET_NAME=<s3-bucket-name>
# prefix to include in path
AWS_STATIC_PREFIX=static
# The directory to upload to S3 (uploads the content of the directory)
AWS_STATIC_SOURCE_DIRECTORY=public

Exported Environment Variables to runtime

STATIC_SERVER=<AWS_STATIC_BUCKET_NAME>.s3.amazonaws.com
STATIC_PATH=/<AWS_STATIC_PREFIX>/<YYYY-MM-DD>/<git-commit-sha1>

These variables can be overriden with config vars as expected

heroku config:set STATIC_SERVER=your.cdn.host

To return to the default value just unset the config vars

heroku config:unset STATIC_SERVER
