MetaSchema get_meta_doc) ALL_DISTROSDistroug_util) PER_INSTANCE)update_ssh_configa This module consumes three top-level config keys: ``ssh_pwauth``, ``chpasswd``
and ``password``.
The ``ssh_pwauth`` config key determines whether or not sshd will be configured
to accept password authentication.
The ``chpasswd`` config key accepts a dictionary containing either or both of
``users`` and ``expire``. The ``users`` key is used to assign a password to a
corresponding pre-existing user. The ``expire`` key is used to set
whether to expire all user passwords specified by this module,
such that a password will need to be reset on the user's next login.
.. note::
Prior to cloud-init 22.3, the ``expire`` key only applies to plain text
(including ``RANDOM``) passwords. Post 22.3, the ``expire`` key applies to
both plain text and hashed passwords.
``password`` config key is used to set the default user's password. It is
ignored if the ``chpasswd`` ``users`` is used. Note: the ``list`` keyword is
deprecated in favor of ``users``.
