Using CLI in Ansible 2.5
================================================================================
Example CLI ``group_vars/eos.yml``
----------------------------------
.. code-block:: yaml
ansible_connection: network_cli
ansible_network_os: eos
ansible_user: myuser
ansible_ssh_pass: !vault...
ansible_become: yes
ansible_become_method: enable
ansible_become_pass: !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_ssh_pass`` 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 via environment variables.
Example CLI Task
----------------
.. code-block:: yaml
- name: Backup current switch config (eos)
eos_config:
backup: yes
register: backup_eos_location
when: ansible_network_os == 'eos'
Using eAPI in Ansible 2.5
================================================================================
Enabling eAPI
-------------
Before you can use eAPI to connect to a switch, you must enable eAPI. To enable eAPI on a new switch via Ansible, use the ``eos_eapi`` module via the CLI connection. Set up group_vars/eos.yml just like in the CLI example above, then run a playbook task like this:
.. code-block:: yaml
- name: Enable eAPI
eos_eapi:
enable_http: yes
enable_https: yes
become: true
become_method: enable
when: ansible_network_os == 'eos'
You can find more options for enabling HTTP/HTTPS and local http in the :ref:`eos_eapi <eos_eapi>` module documentation.
Once eAPI is enabled, change your ``group_vars/eos.yml`` to use the eAPI connection.
Example eAPI ``group_vars/eos.yml``
-----------------------------------
.. code-block:: yaml
ansible_connection: local
ansible_network_os: eos
ansible_user: myuser
ansible_ssh_pass: !vault...
eapi:
host: "{{ inventory_hostname }}"
transport: eapi
authorize: yes
auth_pass: !vault...
proxy_env:
http_proxy: http://proxy.example.com:8080
- If you are accessing your host directly (not through a web proxy) you can remove the ``proxy_env`` configuration.
- If you are accessing your host through a web proxy using ``https``, change ``http_proxy`` to ``https_proxy``.
Example eAPI Task
-----------------
.. code-block:: yaml
- name: Backup current switch config (eos)
eos_config:
backup: yes
provider: "{{ eapi }}"
register: backup_eos_location
environment: "{{ proxy_env }}"
when: ansible_network_os == 'eos'
In this example two variables defined in ``group_vars`` get passed to the module of the task:
- the ``eapi`` variable gets passed to the ``provider`` option of the module
- the ``proxy_env`` variable gets passed to the ``environment`` option of the module

For legacy playbooks, Ansible still supports ``ansible_connection: local`` on all JUNOS modules. We recommend modernizing to use ``ansible_connection: netconf`` or ``ansible_connection: network_cli`` as soon as possible.
Using CLI in Ansible 2.5
================================================================================
Example CLI ``group_vars/junos.yml``
------------------------------------
.. code-block:: yaml
ansible_connection: network_cli
ansible_network_os: junos
ansible_user: myuser
ansible_ssh_pass: !vault...

junos_config:
backup: yes

Using NETCONF in Ansible 2.5
================================================================================
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 via Ansible, use the ``junos_netconf`` module via the CLI connection. Set up group_vars/junos.yml just like in the CLI example above, then run a playbook task like this:
.. code-block:: yaml
- name: Enable NETCONF
junos_netconf:
when: ansible_network_os == 'junos'
Once NETCONF is enabled, change your ``group_vars/junos.yml`` to use the NETCONF connection.
Example NETCONF ``group_vars/junos.yml``
----------------------------------------
.. code-block:: yaml
ansible_connection: netconf
ansible_network_os: junos

To find out more about the options for enabling HTTP/HTTPS and local http see the :ref:`nxos_nxapi <nxos_nxapi>` module documentation.
Once NX-API is enabled, change your ``group_vars/nxos.yml`` to use the NX-API connection.
Example NX-API ``group_vars/nxos.yml``
--------------------------------------
.. code-block:: yaml
ansible_connection: local
ansible_network_os: nxos
ansible_user: myuser
ansible_ssh_pass: !vault...
nxapi:
host: "{{ inventory_hostname }}"
transport: nxapi
proxy_env:
http_proxy: http://proxy.example.com:8080
- If you are accessing your host directly (not through a web proxy) you can remove the ``proxy_env`` configuration.
- If you are accessing your host through a web proxy using ``https``, change ``http_proxy`` to ``https_proxy``.
Example NX-API Task
-------------------

In this example two variables defined in ``group_vars`` get passed to the module of the task:
