salt.states.netconfig.commit_cancelled(name)

New in version 2019.2.0.

Cancel a commit scheduled to be executed via the commit_in and commit_at arguments from the net.load_template or net.load_config execution functions. The commit ID is displayed when the commit is scheduled via the functions named above.

State SLS Example:

'20180726083540640360':
  netconfig.commit_cancelled

salt.states.netconfig.commit_confirmed(name)

New in version 2019.2.0.

Confirm a commit scheduled to be reverted via the revert_in and revert_at arguments from the net.load_template or net.load_config execution functions. The commit ID is displayed when the commit confirmed is scheduled via the functions named above.

State SLS Example:

'20180726083540640360':
  netconfig.commit_confirmed

salt.states.netconfig.managed(name, template_name=None, template_source=None, template_hash=None, template_hash_name=None, saltenv='base', template_engine='jinja', skip_verify=False, context=None, defaults=None, test=False, commit=True, debug=False, replace=False, commit_in=None, commit_at=None, revert_in=None, revert_at=None, **template_vars)

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:

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

Changed in version 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:

• cheetah
• genshi
• jinja
• mako
• py
• 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.

Changed in version 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 state.sls or 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 net.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).

New in version 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.

New in version 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 net.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.

New in version 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

New in version 2019.2.0.

replace: False

Load and replace the configuration. Default: False (will apply load merge).

context: None

Overrides default context variables passed to the template.

New in version 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.

SLS Example (e.g.: under salt://router/config.sls) :

whole_config_example:
    netconfig.managed:
        - template_name: salt://path/to/complete_config.jinja
        - debug: True
        - replace: True
bgp_config_example:
    netconfig.managed:
        - template_name: /absolute/path/to/bgp_neighbors.mako
        - template_engine: mako
prefix_lists_example:
    netconfig.managed:
        - template_name: prefix_lists.cheetah
        - debug: True
        - template_engine: cheetah
ntp_peers_example:
    netconfig.managed:
        - template_name: http://bit.ly/2gKOj20
        - skip_verify: False
        - debug: True
        - peers:
            - 192.168.0.1
            - 192.168.0.1
ntp_peers_example_using_pillar:
    netconfig.managed:
        - template_name: http://bit.ly/2gKOj20
        - peers: {{ pillar.get('ntp.peers', []) }}

Multi template example:

hostname_and_ntp:
  netconfig.managed:
    - template_name:
        - https://bit.ly/2OhSgqP
        - https://bit.ly/2M6C4Lx
        - https://bit.ly/2OIWVTs
    - debug: true
    - context:
        hostname: {{ opts.id }}
        servers:
          - 172.17.17.1
          - 172.17.17.2
        peers:
          - 192.168.0.1
          - 192.168.0.2

Usage examples:

$ sudo salt 'juniper.device' state.sls router.config test=True

$ sudo salt -N all-routers state.sls router.config pillar="{'debug': True}"

router.config depends on the location of the SLS file (see above). Running this command, will be executed all five steps from above. These examples above are not meant to be used in a production environment, their sole purpose is to provide usage examples.

Output example:

$ sudo salt 'juniper.device' state.sls router.config test=True

salt.states.netconfig.replace_pattern(name, pattern, repl, count=0, flags=8, bufsize=1, append_if_not_found=False, prepend_if_not_found=False, not_found_content=None, search_only=False, show_changes=True, backslash_literal=False, source='running', path=None, test=False, replace=True, debug=False, commit=True)

New in version 2019.2.0.

Replace occurrences of a pattern in the configuration source. 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 sub().

pattern

A regular expression, to be matched using Python's 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:

update_policy_name:
  netconfig.replace_pattern:
    - pattern: OLD-POLICY-NAME
    - repl: new-policy-name
    - debug: true

salt.states.netconfig.saved(name, source='running', user=None, group=None, mode=None, attrs=None, makedirs=False, dir_mode=None, replace=True, backup='', show_changes=True, create=True, tmp_dir='', tmp_ext='', encoding=None, encoding_errors='strict', allow_empty=False, follow_symlinks=True, check_cmd=None, win_owner=None, win_perms=None, win_deny_perms=None, win_inheritance=True, win_perms_reset=False, **kwargs)

New in version 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 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 backup_mode documentation 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:

/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
