module: bigip_ssl_certificate
short_description: Import/Delete certificates from BIG-IP
description:
- This module will import/delete SSL certificates on BIG-IP LTM.
Certificates can be imported from certificate and key files on the local
disk, in PEM format.
version_added: 2.2
options:
content:
description:
- Sets the contents of a certificate directly to the specified value.
This is used with lookup plugins or for anything with formatting or
- C(content) must be provided when C(state) is C(present).
aliases: ['cert_content']
state:
description:
- Certificate state. This determines if the provided certificate
and key is to be made C(present) on the device or C(absent).
default: present
choices:
- present
- absent
name:
description:
- SSL Certificate Name. This is the cert name used when importing a certificate
into the F5. It also determines the filenames of the objects on the LTM.
required: True
issuer_cert:
description:
- Issuer certificate used for OCSP monitoring.
- This parameter is only valid on versions of BIG-IP 13.0.0 or above.
version_added: 2.5
partition:
description:
- Device partition to manage resources on.
default: Common
version_added: 2.5
notes:
- This module does not behave like other modules that you might include in
roles where referencing files or templates first looks in the role's
files or templates directory. To have it behave that way, use the Ansible
file or template lookup (see Examples). The lookups behave as expected in
a role context.
