S3 Download Buildpack

This is a Heroku Buildpack that can download files from private Amazon S3 buckets. It gives you a way of deploying pre-built code to Heroku without making it publicly accessible.

Usage

$ heroku config:add BUILDPACK_URL=https://github.com/paleozogt/s3-download-buildpack.git

$ cat .buildpack-s3-downloads
AWS_ACCESS_KEY_ID=AKIA0000000000000000
AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
s3://bucket/path/to/tarball.tgz
s3://bucket/path/to/somethingelse.zip

You probably want to use an IAM key with limited access. This code only requires s3:GetObject access to files.

If you don't want to check your IAM keys into revision control, you can store them in Heroku's config system. Keys specified in the .buildpack-s3-downloads file have precedence over keys in the config system.

$ heroku config:add BUILDPACK_URL=https://github.com/paleozogt/s3-download-buildpack.git
$ heroku config:add AWS_ACCESS_KEY_ID=AKIA0000000000000000
$ heroku config:add AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

$ cat .buildpack-s3-downloads
s3://bucket/path/to/tarball.tgz

In most cases you'll use this buildpack in conjunction with other buildpacks using heroku-buildpack-multi:

$ heroku config:add BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

$ cat .buildpack-s3-downloads
AWS_ACCESS_KEY_ID=AKIA0000000000000000
AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
s3://bucket/path/to/tarball.tgz

$ cat .buildpacks
https://github.com/paleozogt/s3-download-buildpack.git
https://github.com/ryandotsmith/null-buildpack.git
