-----------------------------------
Summary: add support to EC2 NodeDriver for passing Block Device
Mappings (for ephemeral instance storage)
Key: LIBCLOUD-282
URL: https://issues.apache.org/jira/browse/LIBCLOUD-282
Project: Libcloud
Issue Type: Improvement
Components: Compute
Affects Versions: 0.11.2
Reporter: joe miller
When creating an EC2 node that utilizes EBS-backed root storage the ephemeral
instance storage disks are not available unless explicitly requested by
including BlockDeviceMappings in the call to RunInstances.
This patch adds support for passing an array of BlockDeviceMappings to the
EC2NodeDriver's create_node() function using the ex_blockdevicemappings kwarg.
Example:
{code}
ec2_ephemeral_mappings = [{'DeviceName': '/dev/sdb', 'VirtualName':
'ephemeral0'},
{'DeviceName': '/dev/sdc', 'VirtualName':
'ephemeral1'},
{'DeviceName': '/dev/sdd', 'VirtualName':
'ephemeral2'}]
ec2.create_node(name=name, image=image, size=size,
ex_blockdevicemappings=ec2_ephemeral_mappings)
[{'DeviceName': '/dev/sdb', 'VirtualName': 'ephemeral0'}]
{code}
