Junos OS Platform Options
***************************************
The `Juniper Junos OS <https://galaxy.ansible.com/junipernetworks/junos>`_ supports multiple connections. This page offers details on how each connection works in Ansible and how to use it.

Connections available
================================================================================
.. table::
:class: documentation-table
==================== ========================================== =========================
.. CLI NETCONF
``junos_netconf`` & ``junos_command`` all modules except ``junos_netconf``,
modules only which enables NETCONF
==================== ========================================== =========================
Protocol SSH XML over SSH
Credentials uses SSH keys / SSH-agent if present uses SSH keys / SSH-agent if present

.. |enable_mode| replace:: Enable Mode |br| (Privilege Escalation)
The ``ansible_connection: local`` has been deprecated. Please use ``ansible_connection: ansible.netcommon.network_cli`` or ``ansible_connection: ansible.netcommon.netconf`` instead.
Using CLI in Ansible
====================
Example CLI inventory ``[junos:vars]``
--------------------------------------
.. code-block:: yaml
[junos:vars]
ansible_connection=ansible.netcommon.network_cli
ansible_network_os=junipernetworks.junos.junos
ansible_user=myuser
ansible_password=!vault...
ansible_ssh_common_args='-o ProxyCommand="ssh -W %h:%p -q bastion01"'
- If you are using SSH keys (including an ssh-agent) you can remove the ``ansible_password`` configuration.
- If you are accessing your host directly (not through a bastion/jump host) you can remove the ``ansible_ssh_common_args`` configuration.
- If you are accessing your host through a bastion/jump host, you cannot include your SSH password in the ``ProxyCommand`` directive. To prevent secrets from leaking out (for example in ``ps`` output), SSH does not support providing passwords through environment variables.
Example CLI task
----------------
.. code-block:: yaml
- name: Retrieve Junos OS version
junipernetworks.junos.junos_command:
commands: show version
when: ansible_network_os == 'junipernetworks.junos.junos'
Using NETCONF in Ansible
========================
Enabling NETCONF
----------------
Before you can use NETCONF to connect to a switch, you must:
- install the ``ncclient`` python package on your control node(s) with ``pip install ncclient``
- enable NETCONF on the Junos OS device(s)
To enable NETCONF on a new switch through Ansible, use the ``junipernetworks.junos.junos_netconf`` module through the CLI connection. Set up your platform-level variables just like in the CLI example above, then run a playbook task like this:
.. code-block:: yaml
- name: Enable NETCONF
connection: ansible.netcommon.network_cli
junipernetworks.junos.junos_netconf:
when: ansible_network_os == 'junipernetworks.junos.junos'
Once NETCONF is enabled, change your variables to use the NETCONF connection.
Example NETCONF inventory ``[junos:vars]``
------------------------------------------
.. code-block:: yaml
[junos:vars]
ansible_connection=ansible.netcommon.netconf
ansible_network_os=junipernetworks.junos.junos
ansible_user=myuser
ansible_password=!vault |
ansible_ssh_common_args='-o ProxyCommand="ssh -W %h:%p -q bastion01"'
Example NETCONF task
--------------------
.. code-block:: yaml
- name: Backup current switch config (junos)
junipernetworks.junos.junos_config:
backup: yes
register: backup_junos_location
when: ansible_network_os == 'junipernetworks.junos.junos'
