short_description: Manages TCL iApp services on a BIG-IP
description:
  - Manages TCL iApp services on a BIG-IP.
  - The API the system uses to communicate with on the BIG-IP is C(/mgmt/tm/sys/application/service/).
version_added: "1.0.0"
options:
  name:
    description:
      - The name of the iApp service you want to deploy.
    type: str
    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.
      - When creating a new service, this parameter is required.
    type: str
  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)
        we recommend you use either the C(file) or C(template) lookups
        to supply the expected parameters.
      - These parameters typically consist of the C(lists), C(tables), and
        C(variables) fields.
    type: dict
  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.
    type: bool
    default: false
  state:
    description:
      - When C(present), ensures the iApp service is created and running.
        When C(absent), ensures the iApp service has been removed.
    type: str
    choices:
      - present
      - absent
    default: present
  partition:
    description:
      - Device partition to manage resources on.
    type: str
    default: Common
  strict_updates:
    description:
      - Indicates whether the application service is tied to the template,
        so when the template is updated, the application service changes to
        reflect the updates.
      - When C(true), disallows any updates to the resources that the iApp
        service has created, if they are not updated directly through the
        iApp.
      - When C(false), allows updates outside of the iApp.
      - If this option is specified in the Ansible task, it takes precedence
        over any similar setting in the iApp Service payload that you provide in
        the C(parameters) field.
    type: bool
  traffic_group:
    description:
      - The traffic group for the iApp service. When creating a new service, if
        this value is not specified, the default of C(/Common/traffic-group-1)
        is used.
      - If this option is specified in the Ansible task, it takes precedence
        over any similar setting in the iApp Service payload that you provide in
        the C(parameters) field.
    type: str
  metadata:
    description:
      - Metadata associated with the iApp service.
      - If this option is specified in the Ansible task, it takes precedence
        over any similar setting in the iApp Service payload that you provide in
        the C(parameters) field.
    type: list
    elements: raw
  description:
    description:
      - Description of the iApp service.
      - If this option is specified in the Ansible task, it takes precedence
        over any similar setting in the iApp Service payload that you provide in
        the C(parameters) field.
    type: str
  device_group:
    description:
      - The device group for the iApp service.
      - If this option is specified in the Ansible task, it takes precedence
        over any similar setting in the iApp Service payload that you provide in
        the C(parameters) field.
