Using this backend, these pushed files are exposed to other Minions via the Salt fileserver. To enable minionfs, :conf_master:`file_recv` needs to be set to ``True`` in the master config file (otherwise :mod:`cp.push <salt.modules.cp.push>` will not be allowed to push files to the Master), and ``minionfs`` must be added to the :conf_master:`fileserver_backends` list. .. code-block:: yaml fileserver_backend: - minionfs .. note:: ``minion`` also works here. Prior to the 2018.3.0 release, *only* ``minion`` would work. Other minionfs settings include: :conf_master:`minionfs_whitelist`, :conf_master:`minionfs_blacklist`, :conf_master:`minionfs_mountpoint`, and :conf_master:`minionfs_env`. .. seealso:: :ref:`tutorial-minionfs` � N�minionfsc C s t td vrdS td rt S dS )z+ Only load if file_recv is enabled Zfileserver_backendFZ file_recv)�__virtualname__�__opts__� r r �L/opt/saltstack/salt/lib/python3.10/site-packages/salt/fileserver/minionfs.py� __virtual__1 s r c C s t jjj| td td d�S )zN Check if the minion is exposed, based on the whitelist and blacklist Zminionfs_whitelistZminionfs_blacklist)Z whitelistZ blacklist)�salt�utils� stringutilsZcheck_whitelist_blacklistr )�minionr r r � _is_exposed: s �r �basec K s ddd�}t j�| �r |S |t� vr|S t j�| �dkr$t�d| � |S tjj � t d �}| t |�d� � t jj�} z | �t jd�\}}W n tyP | Y S w t|�sW|S t j�t d d |d |�}t j�|�r�tj�t |�s�||d < | |d < tt �|��|d < |S |S )z6 Search the environment for the relative path � )�path�relztop.slszIminionfs will NOT serve top.sls for security reasons (path requested: %s)�minionfs_mountpointN� �cachedir�minions�filesr r �stat)�osr �isabs�envs�basename�log�debugr r �url� strip_protor �len�lstrip�sep�split� ValueErrorr �join�isfile� fileserver�is_file_ignored�listr )r Ztgt_env�kwargs�fnd� mountpointr Z pushed_file�fullr r r � find_fileE s6 � �r- c C s t d gS )z] Returns the one environment specified for minionfs in the master configuration.
