module: compute_flavor
short_description: Manage OpenStack compute flavors
author: OpenStack Ansible SIG
description:
- Add or remove flavors from OpenStack.
options:
state:
description:
- Indicate desired state of the resource. When I(state) is 'present',
then I(ram), I(vcpus), and I(disk) are all required. There are no
default values for those parameters.
choices: ['present', 'absent']
default: present
type: str
name:
description:
- Flavor name.
required: true
type: str
ram:
description:
- Amount of memory, in MB.
type: int
vcpus:
description:
- Number of virtual CPUs.
type: int
disk:
description:
- Size of local disk, in GB.
default: 0
type: int
ephemeral:
description:
- Ephemeral space size, in GB.
default: 0
type: int
swap:
description:
- Swap space size, in MB.
default: 0
type: int
rxtx_factor:
description:
- RX/TX factor.
default: 1.0
type: float
is_public:
description:
- Make flavor accessible to the public.
type: bool
default: 'yes'
flavorid:
description:
- ID for the flavor. This is optional as a unique UUID will be
assigned if a value is not specified.
default: "auto"
type: str
extra_specs:
description:
- Metadata dictionary
type: dict
requirements:
- "python >= 3.6"
- "openstacksdk"
