module: rhnreg_ks
short_description: Manage Red Hat Network registration using the C(rhnreg_ks) command
description:
- Manage registration to the Red Hat Network.
version_added: "1.2"
author: James Laska
notes:
- In order to register a system, rhnreg_ks requires either a username and password, or an activationkey.
requirements:
- rhnreg_ks
options:
state:
description:
- whether to register (C(present)), or unregister (C(absent)) a system
required: false
choices: [ "present", "absent" ]
default: "present"
username:
description:
- Red Hat Network username
required: False
default: null
password:
description:
- Red Hat Network password
required: False
default: null
server_url:
description:
- Specify an alternative Red Hat Network server URL
required: False
default: Current value of I(serverURL) from C(/etc/sysconfig/rhn/up2date) is the default
activationkey:
description:
- supply an activation key for use with registration
required: False
default: null
channels:
description:
- Optionally specify a list of comma-separated channels to subscribe to upon successful registration.
required: false
default: []
examples:
- code: rhnreg_ks state=absent username=joe_user password=somepass
description: Unregister system from RHN.
- code: rhnreg_ks state=present username=joe_user password=somepass
description: Register as user I(joe_user) with password I(somepass) and auto-subscribe to available content.
- code: rhnreg_ks state=present activationkey=1-222333444 enable_eus=true
description: Register with activationkey I(1-222333444) and enable extended update support.
- code: rhnreg_ks state=present username=joe_user password=somepass server_url=https://xmlrpc.my.satellite/XMLRPC
description: Register as user I(joe_user) with password I(somepass) against a satellite server specified by I(server_url).
- code: rhnreg_ks state=present username=joe_user password=somepass channels=rhel-x86_64-server-6-foo-1,rhel-x86_64-server-6-bar-1
description: Register as user I(joe_user) with password I(somepass) and enable channels I(rhel-x86_64-server-6-foo-1) and I(rhel-x86_64-server-6-bar-1).
