chef-ebs

This is a cookbook that makes it easy to create/attach EBS volumes, and create
filesystems and RAID arrays on them.

Usage

Add recipe[ebs] to your run list, and configure these attributes:

RAID Array Creation

Create a RAID 10 across four 10GB volumes, format it with XFS, and mount it on
/data.

{
  :ebs => {
    :raids => {
      '/dev/md0' => {
        :num_disks => 4,
        :disk_size => 10,
        :raid_level => 10,
        :fstype => 'xfs',
        :mount_point => '/data',
        :uselvm => true,
        :persistent_volumes => [
          "vol-xxxxxxxx",
          "vol-xxxxxxxx",
          "vol-xxxxxxxx",
          "vol-xxxxxxxx"
        ]
      }
    }
  }
}

EBS Volume Creation

Create a 10GB volume, format it with XFS, and mount it on /data.

{
  :ebs => {
    :volumes => {
      '/data' => {
        :size => 10,
        :fstype => 'xfs'
      }
    }
  }
}

Credentials

Expects a credentials databag with an aws item that contains access_key_id and secret_access_key.

You can override the databag and item names with node[:ebs][:creds][:databag], and node[:ebs][:creds][:item], but the key names are static.
