David Shrewsbury 6970cc233f Wrap calls to main() with if check
A change was merged to the main Ansible core code that can cause

a potential hang if any libraries are called that use threading.

This change was:



  4b0aa1214c



This affected the os_object module by causing a hang on the shade

create_object() API call (which in turn calls swiftclient which

uses threading). The fix is to make sure all modules have a main()

that is wrapped with an "if __name__ == '__main__'" check.

module: os_ironic
short_description: Create/Delete Bare Metal Resources from OpenStack
extends_documentation_fragment: openstack
author: "Monty Taylor (@emonty)"
version_added: "2.0"
description:
- Create or Remove Ironic nodes from OpenStack.
options:
state:
description:
- Indicates desired state of the resource
choices: ['present', 'absent']
default: present
uuid:
description:
- globally unique identifier (UUID) to be given to the resource. Will
be auto-generated if not specified, and name is specified.
- Definition of a UUID will always take precedence to a name value.
required: false
default: None
name:
description:
- unique name identifier to be given to the resource.
required: false
default: None
driver:
description:
- The name of the Ironic Driver to use with this node.
required: true
default: None
chassis_uuid:
description:
- Associate the node with a pre-defined chassis.
required: false
default: None
ironic_url:
description:
- If noauth mode is utilized, this is required to be set to the
endpoint URL for the Ironic API. Use with "auth" and "auth_type"
settings set to None.
required: false
default: None
driver_info:
description:
- Information for this server's driver. Will vary based on which
driver is in use. Any sub-field which is populated will be validated
during creation.
suboptions:
power:
description:
- Information necessary to turn this server on / off.
This often includes such things as IPMI username, password, and IP address.
required: true
deploy:
description:
- Information necessary to deploy this server directly, without using Nova. THIS IS NOT RECOMMENDED.
console:
description:
- Information necessary to connect to this server's serial console. Not all drivers support this.
management:
description:
- Information necessary to interact with this server's management interface. May be shared by power_info in some cases.
required: true
nics:
description:
- 'A list of network interface cards, eg, " - mac: aa:bb:cc:aa:bb:cc"'
required: true
properties:
description:
- Definition of the physical characteristics of this server, used for scheduling purposes
suboptions:
cpu_arch:
description:
- CPU architecture (x86_64, i686, ...)
default: x86_64
cpus:
description:
- Number of CPU cores this machine has
default: 1
ram:
description:
- amount of RAM this machine has, in MB
default: 1
disk_size:
description:
- size of first storage device in this machine (typically /dev/sda), in GB
default: 1
skip_update_of_driver_password:
description:
- Allows the code that would assert changes to nodes to skip the
update if the change is a single line consisting of the password
field. As of Kilo, by default, passwords are always masked to API
requests, which means the logic as a result always attempts to
re-assert the password field.
required: false
default: false
requirements: ["shade", "jsonpatch"]
