C(subscription-manager) itself gets credentials only as arguments of command line parameters, which is I(not) secure, as they can be easily stolen by checking the process listing on the system. Due to limitations of the D-Bus interface of C(rhsm), the module will I(not) use D-Bus for registation when trying either to register using I(token), or when specifying I(environment), or when the system is old (typically RHEL 6 and older). - In order to register a system, subscription-manager requires either a username and password, or an activationkey and an Organization ID. - Since 2.5 values for I(server_hostname), I(server_insecure), I(rhsm_baseurl), I(server_proxy_hostname), I(server_proxy_port), I(server_proxy_user) and I(server_proxy_password) are no longer taken from the C(/etc/rhsm/rhsm.conf) config file and default to None. - It is possible to interact with C(subscription-manager) only as root, so root permissions are required to successfully run this module. - Since community.general 6.5.0, credentials (that is, I(username) and I(password), I(activationkey), or I(token)) are needed only in case the the system is not registered, or I(force_register) is specified; this makes it possible to use the module to tweak an already registered system, for example attaching pools to it (using I(pool), or I(pool_ids)), and modifying the C(syspurpose) attributes (using I(syspurpose)). requirements: - subscription-manager - Optionally the C(dbus) Python library; this is usually included in the OS as it is used by C(subscription-manager). extends_documentation_fragment: - community.general.attributes attributes: check_mode: support: none diff_mode: support: none options: state: description: - whether to register and subscribe (C(present)), or unregister (C(absent)) a system choices: [ "present", "absent" ] default: "present" type: str username: description: - access.redhat.com or Red Hat Satellite or Katello username type: str password: description: - access.redhat.com or Red Hat Satellite or Katello password type: str token: description: - sso.redhat.com API access token. type: str version_added: 6.3.0 server_hostname: description: - Specify an alternative Red Hat Subscription Management or Red Hat Satellite or Katello server type: str server_insecure: description: - Enable or disable https server certificate verification when connecting to C(server_hostname) type: str server_prefix: description: - Specify the prefix when registering to the Red Hat Subscription Management or Red Hat Satellite or Katello server. type: str version_added: 3.3.0 server_port: description: - Specify the port when registering to the Red Hat Subscription Management or Red Hat Satellite or Katello server. type: str version_added: 3.3.0 rhsm_baseurl: description: - Specify CDN baseurl type: str rhsm_repo_ca_cert: description: - Specify an alternative location for a CA certificate for CDN type: str server_proxy_hostname: description: - Specify an HTTP proxy hostname. type: str server_proxy_scheme: description: - Specify an HTTP proxy scheme, for example C(http) or C(https). type: str version_added: 6.2.0 server_proxy_port: description: - Specify an HTTP proxy port. type: str server_proxy_user: description: - Specify a user for HTTP proxy with basic authentication type: str server_proxy_password: description: - Specify a password for HTTP proxy with basic authentication type: str auto_attach: description: - Upon successful registration, auto-consume available subscriptions - Added in favor of deprecated autosubscribe in 2.5. type: bool aliases: [autosubscribe] activationkey: description: - supply an activation key for use with registration type: str org_id: description: - Organization ID to use in conjunction with activationkey type: str environment: description: - Register with a specific environment in the destination org.
