module: apt_key
author: Jayson Vantuyl & others
version_added: "1.0"
short_description: Add or remove an apt key
description:
- Add or remove an I(apt) key, optionally downloading it
notes:
- doesn't download the key unless it really needs it
- as a sanity check, downloaded key id must match the one specified
- best practice is to specify the key id and the url
options:
id:
required: false
default: none
description:
- identifier of key
data:
required: false
default: none
description:
- keyfile contents
file:
required: false
default: none
description:
- keyfile path
keyring:
required: false
default: none
description:
- path to specific keyring file in /etc/apt/trusted.gpg.d
version_added: "1.3"
url:
required: false
default: none
description:
- url to retrieve key from.
keyserver:
required: false
default: none
description:
- keyserver to retrieve key from.
state:
required: false
choices: [ absent, present ]
default: present
description:
- used to specify if key is being added or revoked
validate_certs:
description:
- If C(no), SSL certificates for the target url will not be validated. This should only be used
on personally controlled sites using self-signed certificates.
required: false
default: 'yes'
choices: ['yes', 'no']
