module: bigip_gtm_datacenter
short_description: Manage Datacenter configuration in BIG-IP
description:
- Manage BIG-IP data center configuration. A data center defines the location
where the physical network components reside, such as the server and link
objects that share the same subnet on the network. This module is able to
manipulate the data center definitions in a BIG-IP
version_added: "2.2"
options:
contact:
description:
- The name of the contact for the data center.
description:
description:
- The description of the data center.
enabled:
description:
- Whether the data center should be enabled. At least one of C(state) and
C(enabled) are required.
choices:
- yes
- no
location:
description:
- The location of the data center.
name:
description:
- The name of the data center.
required: true
state:
description:
- The state of the datacenter on the BIG-IP. When C(present), guarantees
that the data center exists. When C(absent) removes the data center
from the BIG-IP. C(enabled) will enable the data center and C(disabled)
will ensure the data center is disabled. At least one of state and
enabled are required.
choices:
- present
- absent
notes:
- Requires the f5-sdk Python package on the host. This is as easy as
pip install f5-sdk.
extends_documentation_fragment: f5
requirements:
- f5-sdk
