module: bigip_iapp_service
short_description: Manages TCL iApp services on a BIG-IP.
description:
- Manages TCL iApp services on a BIG-IP.
version_added: "2.4"
options:
name:
description:
- The name of the iApp service that you want to deploy.
required: True
template:
description:
- The iApp template from which to instantiate a new service. This
template must exist on your BIG-IP before you can successfully
create a service. This parameter is required if the C(state)
parameter is C(present).
parameters:
description:
- A hash of all the required template variables for the iApp template.
If your parameters are stored in a file (the more common scenario)
it is recommended you use either the `file` or `template` lookups
to supply the expected parameters.
force:
description:
- Forces the updating of an iApp service even if the parameters to the
service have not changed. This option is of particular importance if
the iApp template that underlies the service has been updated in-place.
This option is equivalent to re-configuring the iApp if that template
has changed.
default: False
state:
description:
- When C(present), ensures that the iApp service is created and running.
When C(absent), ensures that the iApp service has been removed.
default: present
choices:
- present
- absent
notes:
- Requires the f5-sdk Python package on the host. This is as easy as pip
install f5-sdk.
- Requires the deepdiff Python package on the host. This is as easy as pip
install f5-sdk.
requirements:
- f5-sdk
- deepdiff
