napalm-ansible

Collection of ansible modules that use napalm to retrieve data or modify configuration on networking devices.

Modules

The following modules are currently available:

  • napalm_cli
  • napalm_diff_yang
  • napalm_get_facts
  • napalm_install_config
  • napalm_parse_yang
  • napalm_ping
  • napalm_translate_yang
  • napalm_validate

Action-Plugins

Action-Plugins should be used to make napalm-ansible more consistent with the behavior of other Ansible modules (eliminate the need of a provider and of individual task arguments for hostname, username, password, and timeout).

They provide default parameters for the hostname, username, password and timeout paramters.

  • hostname is set to the first of provider {{ hostname }}, provider {{ host }}, play-context remote_addr.
  • username is set to the first of provider {{ username }}, play-context connection_user.
  • password is set to the first of provider {{ password }}, play-context password (-k argument).
  • timeout is set to the provider {{ timeout }}, or else defaults to 60 seconds (can't be passed via command-line).

Installing

You can install the napalm-ansible collection with the Ansible Galaxy CLI:

ansible-galaxy collection install napalm.napalm

You can also include it in a requirements.yml file and install it with ansible-galaxy collection install -r requirements.yml, using the format:

---
collections:
  - name: napalm.napalm

You will also need to install napalm via Pip as it is a dependency

pip install napalm

Alternatively, you can install it via Pip

pip install napalm napalm-ansible

Or:

git clone https://github.com/napalm-automation/napalm-ansible
pip install napalm

Configuring Ansible

If you have installed napalm-ansible via Pip you will need to add library and actions_plugins paths in ansible.cfg. Instructions can be found by running napalm-ansible

$ cat .ansible.cfg

[defaults]
library = ~/napalm-ansible/napalm_ansible/modules
action_plugins = ~/napalm-ansible/napalm_ansible/plugins/action
...
