If ``show_changes`` is ``True``, then a diff of what changed will be returned, otherwise a ``True`` will be returned when changes are made, and ``False`` when no changes are made. This is a pure Python implementation that wraps Python's :py:func:`~re.sub`. pattern A regular expression, to be matched using Python's :py:func:`~re.search`. repl The replacement text. count: ``0`` Maximum number of pattern occurrences to be replaced. If count is a positive integer ``n``, only ``n`` occurrences will be replaced, otherwise all occurrences will be replaced. flags (list or int): ``8`` A list of flags defined in the ``re`` module documentation from the Python standard library. Each list item should be a string that will correlate to the human-friendly flag name. E.g., ``['IGNORECASE', 'MULTILINE']``. Optionally, ``flags`` may be an int, with a value corresponding to the XOR (``|``) of all the desired flags. Defaults to 8 (which supports 'MULTILINE'). bufsize (int or str): ``1`` How much of the configuration to buffer into memory at once. The default value ``1`` processes one line at a time. The special value ``file`` may be specified which will read the entire file into memory before processing. append_if_not_found: ``False`` If set to ``True``, and pattern is not found, then the content will be appended to the file. prepend_if_not_found: ``False`` If set to ``True`` and pattern is not found, then the content will be prepended to the file. not_found_content Content to use for append/prepend if not found. If None (default), uses ``repl``. Useful when ``repl`` uses references to group in pattern. search_only: ``False`` If set to true, this no changes will be performed on the file, and this function will simply return ``True`` if the pattern was matched, and ``False`` if not. show_changes: ``True`` If ``True``, return a diff of changes made. Otherwise, return ``True`` if changes were made, and ``False`` if not. backslash_literal: ``False`` Interpret backslashes as literal backslashes for the repl and not escape characters. This will help when using append/prepend so that the backslashes are not interpreted for the repl on the second run of the state. source: ``running`` The configuration source. Choose from: ``running``, ``candidate``, or ``startup``. Default: ``running``. path Save the temporary configuration to a specific path, then read from there. test: ``False`` Dry run? If set as ``True``, will apply the config, discard and return the changes. Default: ``False`` and will commit the changes on the device. commit: ``True`` Commit the configuration changes? Default: ``True``. debug: ``False`` Debug mode. Will insert a new key in the output dictionary, as ``loaded_config`` containing the raw configuration loaded on the device. replace: ``True`` Load and replace the configuration. Default: ``True``. If an equal sign (``=``) appears in an argument to a Salt command it is interpreted as a keyword argument in the format ``key=val``. That processing can be bypassed in order to pass an equal sign through to the remote shell command by manually specifying the kwarg: State SLS Example: .. code-block:: yaml update_policy_name: netconfig.replace_pattern: - pattern: OLD-POLICY-NAME - repl: new-policy-name - debug: true r � config.merger r r znet.replace_pattern)�count�flags�bufsize�append_if_not_found�prepend_if_not_found�not_found_content� search_only� show_changes�backslash_literal�source�pathr r r r )r r r � default_retr r � loaded_ret)�name�pattern�replr& r' r( r) r* r+ r, r- r. r/ r0 r r r r �retZ replace_retr r r �replace_patternh s4 x ��r7 � �strictc K s� t d |d�}|d s| i d|d d�S td | fi d|�d |�d |�d |�d |�d |�d|�d| �d| �d| �d|d | �d| �d| �d|�d|�d|�d|�d|�d|�d |�d |�d |�d |�|��S ) a� .. versionadded:: 2019.2.0 Save the configuration to a file on the local file system. name Absolute path to file where to save the configuration. To push the files to the Master, use :mod:`cp.push <salt.modules.cp.push>` Execution function. source: ``running`` The configuration source. Choose from: ``running``, ``candidate``, ``startup``. Default: ``running``. user The user to own the file, this defaults to the user salt is running as on the minion group The group ownership set for the file, this defaults to the group salt is running as on the minion. On Windows, this is ignored mode The permissions to set on this file, e.g. ``644``, ``0775``, or ``4664``. The default mode for new files and directories corresponds to the umask of the salt process. The mode of existing files and directories will only be changed if ``mode`` is specified. .. note:: This option is **not** supported on Windows. attrs The attributes to have on this file, e.g. ``a``, ``i``. The attributes can be any or a combination of the following characters: ``aAcCdDeijPsStTu``. .. note:: This option is **not** supported on Windows. makedirs: ``False`` If set to ``True``, then the parent directories will be created to facilitate the creation of the named file. If ``False``, and the parent directory of the destination file doesn't exist, the state will fail. dir_mode If directories are to be created, passing this option specifies the permissions for those directories. If this is not set, directories will be assigned permissions by adding the execute bit to the mode of the files. The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced. replace: ``True`` If set to ``False`` and the file already exists, the file will not be modified even if changes would otherwise be made. Permissions and ownership will still be enforced, however. backup Overrides the default backup mode for this specific file. See :ref:`backup_mode documentation <file-state-backups>` for more details. show_changes: ``True`` Output a unified diff of the old file and the new file. If ``False`` return a boolean if any changes were made. create: ``True`` If set to ``False``, then the file will only be managed if the file already exists on the system. encoding If specified, then the specified encoding will be used. Otherwise, the file will be encoded using the system locale (usually UTF-8). See https://docs.python.org/3/library/codecs.html#standard-encodings for the list of available encodings. encoding_errors: ``'strict'`` Error encoding scheme. Default is ```'strict'```. See https://docs.python.org/2/library/codecs.html#codec-base-classes for the list of available schemes. allow_empty: ``True`` If set to ``False``, then the state will fail if the contents specified by ``contents_pillar`` or ``contents_grains`` are empty. follow_symlinks: ``True`` If the desired path is a symlink follow it and make changes to the file to which the symlink points. check_cmd The specified command will be run with an appended argument of a *temporary* file containing the new managed contents. If the command exits with a zero status the new managed contents will be written to the managed destination. If the command exits with a nonzero exit code, the state will fail and no changes will be made to the file. tmp_dir Directory for temp file created by ``check_cmd``. Useful for checkers dependent on config file location (e.g. daemons restricted to their own config directories by an apparmor profile). tmp_ext Suffix for temp file created by ``check_cmd``. Useful for checkers dependent on config file extension (e.g. the init-checkconf upstart config checker). win_owner: ``None`` The owner of the directory. If this is not passed, user will be used. If user is not passed, the account under which Salt is running will be used. win_perms: ``None`` A dictionary containing permissions to grant and their propagation. For example: ``{'Administrators': {'perms': 'full_control'}}`` Can be a single basic perm or a list of advanced perms. ``perms`` must be specified. ``applies_to`` does not apply to file objects. win_deny_perms: ``None`` A dictionary containing permissions to deny and their propagation. For example: ``{'Administrators': {'perms': 'full_control'}}`` Can be a single basic perm or a list of advanced perms. ``perms`` must be specified. ``applies_to`` does not apply to file objects. win_inheritance: ``True`` True to inherit permissions from the parent directory, False not to inherit permission. win_perms_reset: ``False`` If ``True`` the existing DACL will be cleared and replaced with the settings defined in this function. If ``False``, new entries will be appended to the existing DACL. Default is ``False``. State SLS Example: .. code-block:: yaml /var/backups/{{ opts.id }}/{{ salt.status.time('%s') }}.cfg: netconfig.saved: - source: running - makedirs: true The state SLS above would create a backup config grouping the files by the Minion ID, in chronological files. For example, if the state is executed at on the 3rd of August 2018, at 5:15PM, on the Minion ``core1.lon01``, the configuration would saved in the file: ``/var/backups/core01.lon01/1533316558.cfg`` z net.config)r/ �resultF�comment)r3 �changesr: r; z file.managed�user�group�mode�attrs�makedirs�dir_moder �backupr- �create�contents�out�tmp_dir�tmp_ext�encoding�encoding_errors� allow_empty�follow_symlinks� check_cmd� win_owner� win_perms�win_deny_perms�win_inheritance�win_perms_reset)r Z __states__)r3 r/ r= r> r? r@ rA rB r rC r- rD rG rH rI rJ rK rL rM rN rO rP rQ rR �kwargsr6 r r r �saved� sl /�������� � � � � ������������rT �basec K s t jj�| �}| p td } td d| �} td d| �} td d| �} td d|�}td d|�}td d|�}td d |�}td d |�}tdi d |�d |�d |�d|�d|�d|�d|�d|�d| �d| �d| �d|�d|�d |�d |�d| �d| �|��}t jj�||| | �S )a�8 Manages the configuration on network devices. By default this state will commit the changes on the device. If there are no changes required, it does not commit and the field ``already_configured`` from the output dictionary will be set as ``True`` to notify that. To avoid committing the configuration, set the argument ``test`` to ``True`` (or via the CLI argument ``test=True``) and will discard (dry run). To preserve the changes, set ``commit`` to ``False`` (either as CLI argument, either as state parameter). However, this is recommended to be used only in exceptional cases when there are applied few consecutive states and/or configuration changes. Otherwise the user might forget that the config DB is locked and the candidate config buffer is not cleared/merged in the running config. To replace the config, set ``replace`` to ``True``. This option is recommended to be used with caution! template_name Identifies path to the template source. The template can be either stored on the local machine, either remotely. The recommended location is under the ``file_roots`` as specified in the master config file. For example, let's suppose the ``file_roots`` is configured as: .. code-block:: yaml file_roots: base: - /etc/salt/states Placing the template under ``/etc/salt/states/templates/example.jinja``, it can be used as ``salt://templates/example.jinja``. Alternatively, for local files, the user can specify the absolute path. If remotely, the source can be retrieved via ``http``, ``https`` or ``ftp``. Examples: - ``salt://my_template.jinja`` - ``/absolute/path/to/my_template.jinja`` - ``http://example.com/template.cheetah`` - ``https:/example.com/template.mako`` - ``ftp://example.com/template.py`` .. versionchanged:: 2019.2.0 This argument can now support a list of templates to be rendered. The resulting configuration text is loaded at once, as a single configuration chunk. template_source: None Inline config template to be rendered and loaded on the device. template_hash: None Hash of the template file. Format: ``{hash_type: 'md5', 'hsum': <md5sum>}`` template_hash_name: None When ``template_hash`` refers to a remote file, this specifies the filename to look for in that file. saltenv: base Specifies the template environment. This will influence the relative imports inside the templates. template_engine: jinja The following templates engines are supported: - :mod:`cheetah<salt.renderers.cheetah>` - :mod:`genshi<salt.renderers.genshi>` - :mod:`jinja<salt.renderers.jinja>` - :mod:`mako<salt.renderers.mako>` - :mod:`py<salt.renderers.py>` - :mod:`wempy<salt.renderers.wempy>` skip_verify: False If ``True``, hash verification of remote file sources (``http://``, ``https://``, ``ftp://``) will be skipped, and the ``source_hash`` argument will be ignored. .. versionchanged:: 2017.7.1 test: False Dry run? If set to ``True``, will apply the config, discard and return the changes. Default: ``False`` (will commit the changes on the device). commit: True Commit? Default: ``True``. debug: False Debug mode. Will insert a new key under the output dictionary, as ``loaded_config`` containing the raw result after the template was rendered. .. note:: This argument cannot be used directly on the command line. Instead, it can be passed through the ``pillar`` variable when executing either of the :py:func:`state.sls <salt.modules.state.sls>` or :py:func:`state.apply <salt.modules.state.apply>` (see below for an example). commit_in: ``None`` Commit the changes in a specific number of minutes / hours. Example of accepted formats: ``5`` (commit in 5 minutes), ``2m`` (commit in 2 minutes), ``1h`` (commit the changes in 1 hour)`, ``5h30m`` (commit the changes in 5 hours and 30 minutes). .. note:: This feature works on any platforms, as it does not rely on the native features of the network operating system. .. note:: After the command is executed and the ``diff`` is not satisfactory, or for any other reasons you have to discard the commit, you are able to do so using the :py:func:`net.cancel_commit <salt.modules.napalm_network.cancel_commit>` execution function, using the commit ID returned by this function. .. warning:: Using this feature, Salt will load the exact configuration you expect, however the diff may change in time (i.e., if an user applies a manual configuration change, or a different process or command changes the configuration in the meanwhile). .. versionadded:: 2019.2.0 commit_at: ``None`` Commit the changes at a specific time. Example of accepted formats: ``1am`` (will commit the changes at the next 1AM), ``13:20`` (will commit at 13:20), ``1:20am``, etc. .. note:: This feature works on any platforms, as it does not rely on the native features of the network operating system. .. note:: After the command is executed and the ``diff`` is not satisfactory, or for any other reasons you have to discard the commit, you are able to do so using the :py:func:`net.cancel_commit <salt.modules.napalm_network.cancel_commit>` execution function, using the commit ID returned by this function. .. warning:: Using this feature, Salt will load the exact configuration you expect, however the diff may change in time (i.e., if an user applies a manual configuration change, or a different process or command changes the configuration in the meanwhile). .. versionadded:: 2019.2.0 revert_in: ``None`` Commit and revert the changes in a specific number of minutes / hours. Example of accepted formats: ``5`` (revert in 5 minutes), ``2m`` (revert in 2 minutes), ``1h`` (revert the changes in 1 hour)`, ``5h30m`` (revert the changes in 5 hours and 30 minutes). .. note:: To confirm the commit, and prevent reverting the changes, you will have to execute the :mod:`net.confirm_commit <salt.modules.napalm_network.confirm_commit>` function, using the commit ID returned by this function. .. warning:: This works on any platform, regardless if they have or don't have native capabilities to confirming a commit. However, please be *very* cautious when using this feature: on Junos (as it is the only NAPALM core platform supporting this natively) it executes a commit confirmed as you would do from the command line. All the other platforms don't have this capability natively, therefore the revert is done via Salt. That means, your device needs to be reachable at the moment when Salt will attempt to revert your changes. Be cautious when pushing configuration changes that would prevent you reach the device. Similarly, if an user or a different process apply other configuration changes in the meanwhile (between the moment you commit and till the changes are reverted), these changes would be equally reverted, as Salt cannot be aware of them. .. versionadded:: 2019.2.0 revert_at: ``None`` Commit and revert the changes at a specific time. Example of accepted formats: ``1am`` (will commit and revert the changes at the next 1AM), ``13:20`` (will commit and revert at 13:20), ``1:20am``, etc. .. note:: To confirm the commit, and prevent reverting the changes, you will have to execute the :mod:`net.confirm_commit <salt.modules.napalm_network.confirm_commit>` function, using the commit ID returned by this function. .. warning:: This works on any platform, regardless if they have or don't have native capabilities to confirming a commit.

Default: ``False`` (will apply load merge). context: None Overrides default context variables passed to the template. .. versionadded:: 2019.2.0 defaults: None Default variables/context passed to the template. template_vars Dictionary with the arguments/context to be used when the template is rendered. Do not explicitly specify this argument. This represents any other variable that will be sent to the template rendering system. Please see an example below! In both ``ntp_peers_example_using_pillar`` and ``ntp_peers_example``, ``peers`` is sent as template variable. .. note:: It is more recommended to use the ``context`` argument instead, to avoid any conflicts with other arguments.
