State Caching
-------------

When a highstate is called, the minion automatically caches a copy of the last
high data. If you then run a highstate with cache=True it will use that cached
highdata and won't hit the fileserver except for ``salt://`` links in the
states themselves.

    queue : False
        Instead of failing immediately when another state run is in progress,
        queue the new state run to begin running once the other has finished.

        This option starts a new thread for each queued state run, so use this
        option sparingly.

    localconfig
        Optionally, instead of using the minion config, load minion opts from
        the file specified by this argument, and then merge them with the
        options from the minion config. This functionality allows for specific
        states to be run with their own custom minion configuration, including
        different pillars, file_roots, etc.

        .. code-block:: bash

            salt '*' state.apply localconfig=/path/to/minion.yml


    .. rubric:: APPLYING INDIVIDUAL SLS FILES (A.K.A. :py:func:`STATE.SLS <salt.modules.state.sls>`)

    To apply individual SLS files, pass them as a comma-separated list:

    .. code-block:: bash

        # Run the states configured in salt://stuff.sls (or salt://stuff/init.sls)
        salt '*' state.apply stuff

        # Run the states configured in salt://stuff.sls (or salt://stuff/init.sls)
        # and salt://pkgs.sls (or salt://pkgs/init.sls).
        salt '*' state.apply stuff,pkgs

        # Run the states configured in a more deeply nested directory such as salt://my/organized/stuff.sls (or salt://my/organized/stuff/init.sls)
        salt '*' state.apply my.organized.stuff

    The following additional arguments are also accepted when applying
    individual SLS files:

    test
        Run states in test-only (dry-run) mode

    mock
        The mock option allows for the state run to execute without actually
        calling any states. This then returns a mocked return which will show
        the requisite ordering as well as fully validate the state run.

        .. versionadded:: 2015.8.4

    pillar
        Custom Pillar values, passed as a dictionary of key-value pairs

        .. code-block:: bash

            salt '*' state.apply stuff pillar='{"foo": "bar"}'

        .. note::
            Values passed this way will override Pillar values set via
            ``pillar_roots`` or an external Pillar source.

    queue : False
        Instead of failing immediately when another state run is in progress,
        queue the new state run to begin running once the other has finished.

        This option starts a new thread for each queued state run, so use this
        option sparingly.

    concurrent : False
        Execute state runs concurrently instead of serially

        .. warning::

            This flag is potentially dangerous. It is designed for use when
            multiple state runs can safely be run at the same time. Do *not*
            use this flag for performance optimization.

    saltenv
        Specify a salt fileserver environment to be used when applying states

        .. versionchanged:: 0.17.0
            Argument name changed from ``env`` to ``saltenv``

        .. versionchanged:: 2014.7.0
            If no saltenv is specified, the minion config will be checked for an
            ``environment`` parameter and if found, it will be used. If none is
            found, ``base`` will be used. In prior releases, the minion config
            was not checked and ``base`` would always be assumed when the
            saltenv was not explicitly set.

    pillarenv
        Specify a Pillar environment to be used when applying states. This
        can also be set in the minion config file using the
        :conf_minion:`pillarenv` option. When neither the
        :conf_minion:`pillarenv` minion config option nor this CLI argument is
        used, all Pillar environments will be merged together.

    localconfig
        Optionally, instead of using the minion config, load minion opts from
        the file specified by this argument, and then merge them with the
        options from the minion config. This functionality allows for specific

        .. code-block:: bash

            salt '*' state.apply stuff localconfig=/path/to/minion.yml

    sync_mods
        If specified, the desired custom module types will be synced prior to
        running the SLS files:

        .. code-block:: bash

            salt '*' state.apply stuff sync_mods=states,modules
            salt '*' state.apply stuff sync_mods=all

        .. note::
            This option is ignored when no SLS files are specified, as a
            :ref:`highstate <running-highstate>` automatically syncs all custom
            module types.

    localconfig
        Optionally, instead of using the minion config, load minion opts from
        the file specified by this argument, and then merge them with the
        options from the minion config. This functionality allows for specific
        states to be run with their own custom minion configuration, including
        different pillars, file_roots, etc.

    mock
        The mock option allows for the state run to execute without actually
        calling any states. This then returns a mocked return which will show
        the requisite ordering as well as fully validate the state run.

    Watch Salt's event bus and block until the given tag is matched

    .. versionadded:: 2016.3.0
    .. versionchanged:: 2019.2.0
        ``tagmatch`` can now be either a glob or regular expression.

    This is useful for utilizing Salt's event bus from shell scripts or for
    taking simple actions directly from the CLI.

    Enable debug logging to see ignored events.

    :param tagmatch: the event is written to stdout for each tag that matches
        this glob or regular expression.
    :param count: this number is decremented for each event that matches the
        ``tagmatch`` parameter; pass ``-1`` to listen forever.
    :param quiet: do not print to stdout; just block
    :param sock_dir: path to the Salt master's event socket file.
    :param pretty: Output the JSON all on a single line if ``False`` (useful
        for shell tools); pretty-print the JSON output if ``True``.
    :param node: Watch the minion-side or master-side event bus.
