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
authors:
- Jesse Keating <jesse.keating@rackspace.com>
- Paul Durivage <paul.durivage@rackspace.com>
notes:
- One environment variable needs to be set: RAX_CREDS_FILE.
- RAX_CREDS_FILE points to a credentials file appropriate for pyrax.
- Another optional environment variable may be set: RAX_REGION.
- RAX_REGION defines one or more Rackspace Public Cloud regions (DFW, ORD, LON, ...)
as a comma-separated list of region names. If set to "all" or omitted, all
regions in pyrax.regions will be used.
- See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating
requirements: [ "pyrax" ]
examples:
- description: List server instances
code: RAX_CREDS_FILE=~/.raxpub rax.py --list
- description: List server instances only in DFW and ORD regions
code: RAX_CREDS_FILE=~/.raxpub RAX_REGION=DFW,ORD rax.py --list
