azure_file cookbook

Description

This cookbook provides a Lightweight Resource and Provider
to download files from Azure blob storage. It's a replacement for the s3_file
cookbook for Azure.

Requirements

• A Microsoft Azure account is required.
• Requires Chef 0.7.10 or higher for Lightweight Resource and Provider support. Chef 0.8+ is recommended. Download and Install the Chef DK.

NOTE: azure-storage-common gem has runtime dependencies
on azure-core and nokogiri
both of which are embedded in the Chef DK Ruby gems.

Quickstart

mkdir cookbooks
cd cookbooks
git clone https://github.com/adobe/azure_file.git
chef-client --local-mode --override-runlist azure_file

While this cookbook can be used in chef-solo mode, to gain the most flexibility,
we recommend using chef-client with a Chef Server.

Recipes

default.rb

The default recipe installs the azure-storage-common
RubyGem, which this cookbook requires in order to work with the Azure API. Make sure that the azure_file
recipe is in the node or role run_list before any resources from this cookbook are used.

"run_list": [
  "recipe[azure_file]"
]

The gem_package is created as a Ruby Object and thus installed during the Compile
Phase of the Chef run.

Resources and Providers

This cookbook provides one resource and a corresponding provider.

azure_file

This resource is a wrapper around the core remote_file
resource that will generate an expiring link for you to retrieve your file from protected blob storage.

Actions:

• create - create the file
• create_if_missing - create the file if it does not already exist. default
• delete - delete the file
• touch - touch the file

Attribute Parameters:

• storage_account - the azure storage account you are accessing
• access_key - the access key to this azure storage account
• path - where this file will be created on the machine
• remote_path - the path of the file/key to pull including folder
• container - the name of the azure blob storage container/bucket from where to pull

The following parameters are inherited from the remote_file
resource:

• owner
• group
• mode
• checksum
• backup
• inherits
• rights

Example:

azure_file '/tmp/secret_file.jpg' do
  storage_account 'secretstorage'
  access_key 'eW91cmtleWluYmFzZTY0.....'
  container 'images'
  remote_path 'secret_file.jpg'
end
