Overview

This module presents a type and provider for fetching files from amazon s3 using IAM profiles.

Setup

gem install aws-sdk => version 2

If you've already installed version and rely on it you'll have to look into the rdoc for the SDK since V2 is reverse breaking to V1.

Mainly:

Upgrading - Client Classes - Versioned client classes removed, e.g. Aws::S3::Client::V20060301.new is now Aws::S3::Client. new The :api_version constructor option is no longer accepted.

Upgrading - Aws Module - Helper methods on Aws for client classes deprecated; For example, calling Aws.s3 will generate a deprecation warning. Use Aws::S3::Client.new instead. Helpers will be removed as of v2.0.0 final.

Usage

Put the classes, types, and resources for customizing, configuring, and doing the fancy stuff with your module here.

Reference

Types

Currently this module has a single type and provider 's3'. The 's3' resource is instanciated as such:

s3 { '/path/to/file/on/my/local/filesystem':
    # Required paramters:
    ensure              => present,
    source              => '/bucket/path/to/object',
    access_key_id       => 'mysecret',
    secret_access_key   => 'anothersecret',
    # Optional parameters:
    region              => 'us-west-1', # Defaults to us-east-1
}

This provider is 'psudo-idempotent' in that the exists? method, on each run, has to pull down the S3 object in order to compare it to the one of the local filesystem.

In order to do this comparison it creates a temp file in the same path as the file on the local filesystem and pulls down the S3 resource. It then compares the MD5 checksum of each resource, the local file and the S3 object. If this returns true, the filesystem is not written to; if it returns false, the new resource is written.

Currently, on each run, the S3 object is actually pulled down twice since exists? and create methods both grab the object. This isn't great for performance and I would like to update this in future versions.

Limitations

The S3 type and provider rely on aws-sdk 'version -> 2'. There is a feature which the provider is :confined to that will post-pone S3 resources until the gems for the aws-sdk are present on the local filesystem. Ensure to include s3 in your catalogue so those gems get installed.

Todo

• Better &more testing.
• Better checking to determine if a file must be downloaded or not
