short_description: Manage software images on a BIG-IP
description:
- Manages software images on a BIG-IP. These images may include both base images
and hotfix images.
version_added: 2.7
options:
force:
description:
- When C(yes), will upload the file every time and replace the file on the
device.
- When C(no), the file will only be uploaded if it does not already
exist.
- Generally should be C(yes) only in cases where you have reason
to believe that the image was corrupted during upload.
default: no
type: bool
state:
description:
- When C(present), ensures that the image is uploaded.
- When C(absent), ensures that the image is removed.
default: present
choices:
- absent
- present
image:
description:
- The image to put on the remote device.
- This may be an absolute or relative location on the Ansible controller.
- Image names, whether they are base ISOs or hotfix ISOs, B(must) be unique.
