问题描述:

I am stuck on listing all the volumes and volume-ids associated to ec2 instance.

I am seeking to list the ebs-optimized volume attached to it.

ec2 = AWS::EC2.new(

:access_key_id => 'QWERTYUIOPASD',

:secret_access_key => 'qwertyuiasdfghzxcvbn1234567'

)

ec2.instances["i-qwerty1"].block_device_mappings

It is only returning the root volume's id.

{"/dev/sda1"=><AWS::EC2::Attachment volume_id:vol-123456 instance_id:i-qwerty1 device:/dev/sda1>} ```

Is there any method which can list all associated volume-ids.

I even tried using ec2 internal meta-data, which only provided ami volume details

$ curl -L http://169.254.169.254/latest/meta-data/block-device-mapping

$ ami

Also the instance is being managed in Chef. I even checked ohai data for the instance. I can't find the list of volumes attached to it.

Please help!! :)

网友答案:

I have solved it.

We can use

ec2.instances[JSON.parse(<Node>.to_s).automatic.ec2.instance_id].block_device_mappings["/dev/sda1"].volume.id
