MetaSchema� get_meta_doc)�ug_util)� PER_INSTANCEa� This module configures users and groups. For more detailed information on user
options, see the :ref:`Including users and groups<yaml_examples>` config
example.
Groups to add to the system can be specified under the ``groups`` key as
a string of comma-separated groups to create, or a list. Each item in
the list should either contain a string of a single group to create,
or a dictionary with the group name as the key and string of a single user as
a member of that group or a list of users who should be members of the group.
.. note::
Groups are added before users, so any users in a group list must
already exist on the system.
Users to add can be specified as a string or list under the ``users`` key.
Each entry in the list should either be a string or a dictionary. If a string
is specified, that string can be comma-separated usernames to create or the
reserved string ``default`` which represents the primary admin user used to
access the system. The ``default`` user varies per distribution and is
generally configured in ``/etc/cloud/cloud.cfg`` by the ``default_user`` key.
Each ``users`` dictionary item must contain either a ``name`` or ``snapuser``
key, otherwise it will be ignored. Omission of ``default`` as the first item
in the ``users`` list skips creation the default user. If no ``users`` key is
provided the default behavior is to create the default user via this config::
users:
- default
.. note::
Specifying a hash of a user's password with ``passwd`` is a security risk
if the cloud-config can be intercepted. SSH authentication is preferred.
.. note::
If specifying a doas rule for a user, ensure that the syntax for the rule
is valid, as the only checking performed by cloud-init is to ensure that
the user referenced in the rule is the correct user.
.. note::
If specifying a sudo rule for a user, ensure that the syntax for the rule
is valid, as it is not checked by cloud-init.
.. note::
Most of these configuration options will not be honored if the user
already exists. The following options are the exceptions; they are applied
to already-existing users: ``plain_text_passwd``, ``doas``,
``hashed_passwd``, ``lock_passwd``, ``sudo``, ``ssh_authorized_keys``,
``ssh_redirect_user``.
The ``user`` key can be used to override the ``default_user`` configuration
defined in ``/etc/cloud/cloud.cfg``. The ``user`` value should be a dictionary
which supports the same config keys as the ``users`` dictionary items.
