Scalingo aws kms buildpack

This buildpack is used to download certificate from our S3 bucket.

To use it, you need to set the BUILDPACK_URL environment variable of your app to: https://github.com/Scalingo/multi-buildpack.git and add the following line to your .buildpacks file:

https://github.com/Scalingo/aws-kms-buildpack.git

This script use the following environment variables:

• KMSBP_AWS_BUCKET: The name of the bucket
• KMSBP_AWS_REGION: The name of the region of the bucket (and the sse key)
• KMSBP_AWS_ID: The aws user id
• KMSBP_AWS_TOKEN: The aws user token
• CERTS_INSTALL_PATH: Path to the certificates
• OBJECTS: See below
• FILES: See below

The OBJECTS and FILES are to comma separated strings representing the objects to download from S3 and their filenames on the hardrive.

If we have the following configuration:

OBJECTS=a,b,c
FILES=1.txt,2.txt,3.txt

The buildpack will download the object a from s3 and store him in the $CERTS_INSTALL_PATH/1.txt file, store the b object to $CERTS_INSTALL_PATH/2.txt and store the c object to $CERTS_INSTALL_PATH/3.txt.
