napalm-install-formula

Although the installation of NAPALM is very easy, some underlying Python libraries have certain dependencies on various operating systems. This SaltStack formula provides the necessary state to install the required packages.

Available states

napalm_install

Install the NAPALM and additional community drivers, together with their system requirements.

Pillar

Note

Beginning with release 2.0.0, NAPALM has been reunified into a single monolithic package, and therefore the structure used by this formula has been therefore changed. The previous structure can be still found under the 1.0.0 tag, however this is not recommended usage as the individual drivers are no longer maintained.

Fields:

  • version: The NAPALM version to install.

  • upgrade: Boolean value, defaults to False -- whether should upgrade NAPALM (and the additional drivers, unless a specific version is requested).

  • additional_drivers: A list of NAPALM community drivers to install in addition to the core library. Check out https://github.com/napalm-automation-community/ for the list of available community drivers. Do note however that the community drivers are not maintained by the NAPALM core developers, and they may not be available on the public Python Package Index (PyPI). See https://napalm.readthedocs.io/en/latest/contributing/drivers.html for more details.

    For each of the listed drivers, you can pin to a specific desired version to install. See an example below.

Example Pillar

napalm:
  version: 2.4.0
  additional_drivers:
    - napalm-ros
    - napalm-panos==0.5.1

See pillar.example.

Usage

Note

As NAPALM is mostly used when working with Proxy Minions, it is good to keep in mind this distinction: Proxy Minions manage the network gear, while regular minion(s) manage the server(s) where the Proxy minions run. Hence, this formula is designed to be executed on the regular Minion, in order to prepare the environment for the Proxies.

Hint

While the above is generally true, beginning with Salt release 2019.2.0, once you have NAPALM installed on a regular Minion, you can execute the regular NAPALM functions using salt-call against one device at a time, e.g.,

$ salt-call net.lldp driver=junos host=cr1.thn.lon username=test password=test1234

To avoid passing the above for every command, you can specific these details in the Minion configuration file (typically /etc/salt/minion), e.g.,

napalm:
  driver: junos
  username: test
  password: test1234
  optional_args:
    key_file: /path/to/ssh/key
    ssh_config_file: /path/to/ssh/config

To install, execute:

$ sudo salt-call state.sls napalm_install

From the master, targeting the server(s) where we need to install NAPALM:

$ sudo salt 'server-for-napalm' state.sls napalm_install

Usage Example

$ sudo salt-call state.apply napalm_install
