This is a Knife plugin for AWS S3. The plugin gives knife the ability to list, upload and download to / from S3. For example, if using the Knife CFN plugin, and you want to reference an S3-hosted template, this plugin would allow you to upload to S3 before using CFN.

Some code was pillaged from Neill Turner’s knife-cfn plugin: github.com/neillturner/knife-cfn

Be sure you are running the latest version Chef. Versions earlier than 0.10.0 don’t support plugins. This plugin was developed against chef 11.4.4

gem install chef

This plugin is available as a gem:

If you want to build it yourself from source, you can do so with gem:

git clone https://github.com/brettcave/knife-s3.git knife-s3
cd knife-s3
gem build knife-s3.gemspec

This will build the gem in the project directory. From there, it can be installed locally:

gem install knife-s3-0.0.1.gem

In order to authenticate with the AWS API, you need to configure knife with your AWS Access Key ID and Secret Access Key. This can be done by adding the following to your knife.rb:

knife[:aws_access_key_id] = "ACCESSKEY"
knife[:aws_secret_access_key] = "supersecret"

The ID and secret key can be passed with the --aws-access-key-id and --aws-secret-access-key respectively.
