Invalidator for AWS S3-based Cloudfront distributions

If your Amazon Web Services Cloudfront distribution is based on AWS S3, then this library may be useful to you.

This library fetches all the object keys of a particular S3 bucket and then calls on them the invalidation REST API of Cloudfront.

Install

gem install cf-s3-invalidator

You can specify the configuration as CLI parameters:

cf-s3-inv --key <AWS-KEY> --secret <AWS-SECRET> --distribution <CLOUDFRONT-DISTRIBUTION-ID>

Or you can store them into the file _cf_s3_invalidator.yml:

aws_key: YOUR_AWS_ACCESS_KEY_ID
aws_secret: YOUR_AWS_SECRET_ACCESS_KEY
cloudfront_distribution_id: YOUR_CLOUDFRONT_DISTRIBUTION_ID

Then you can just run:

cf-s3-inv

Run tests:

rake test

Verify that the AWS user has CloudFront permissions. In the AWS web interface, this will be in the permissions section of https://console.aws.amazon.com/iam/home?region=REGION-CODE#users/USERNAME
If you're using cf-s3-invalidator from Travis CI, be sure the credentials are encrypted with the correct key for the repository
