Initial commit of rax inventory plugin
The rax inventory plugin provides a way to discovery inventory in the Rackspace Public Cloud by way of pyrax, the official SDK. Grouping will be done if a group:name is found in the instance metadata. When a single host is queried all the instance details are returned with a rax_ prefix. Because inventory plugins cannot take extra arguments, ENV variables must be set to point to the pyrax compatible credentials file and the region to query against.

notes:
|
||||
- Two environment variables need to be set, RAX_CREDS and RAX_REGION.
|
||||
- RAX_CREDS points to a credentials file appropriate for pyrax
|
||||
- RAX_REGION defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
|
||||
requirements: [ "pyrax" ]
|
||||
examples:
|
||||
- description: List server instances
|
||||
code: RAX_CREDS=~/.raxpub RAX_REGION=ORD rax.py --list
|
||||
- description: List server instance properties
|
||||
code: RAX_CREDS=~/.raxpub RAX_REGION=ORD rax.py --host <HOST_IP>
