inventory: rax
short_description: Rackspace Public Cloud external inventory script
description:
- Generates inventory that Ansible can understand by making API request to Rackspace Public Cloud API
- |
When run against a specific host, this script returns the following variables:
rax_os-ext-sts_task_state
rax_addresses
rax_links
rax_image
rax_os-ext-sts_vm_state
rax_flavor
rax_id
rax_rax-bandwidth_bandwidth
rax_user_id
rax_os-dcf_diskconfig
rax_accessipv4
rax_accessipv6
rax_progress
rax_os-ext-sts_power_state
rax_metadata
rax_status
rax_updated
rax_hostid
rax_name
rax_created
rax_tenant_id
rax__loaded
where some item can have nested structure.
- credentials are set in a credentials file
version_added: None
options:
creds_file:
description:
- File to find the Rackspace Public Cloud credentials in
required: true
default: null
region_name:
description:
- Region name to use in request
required: false
default: DFW
author: Jesse Keating
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>
