The Ansible Juniper module requires the Juniper PyEZ package and NETCONF. If you have been following the API example in Chapter 6, APIs and Intent-Driven Networking, you are good to go. If not, refer back to that section for installation instructions as well as some test script to make sure PyEZ works. The Python package called jxmlease is also required:

$ sudo pip install jxmlease

In the host file, we will specify the device and connection variables:

[junos_devices]
J1 ansible_host=192.168.24.252

[junos_devices:vars]
username=juniper
password=juniper!

In our Juniper playbook, we will use the junos_facts module to gather basic facts for the device. This module is equivalent to the setup module and will come in handy if we need to take action depending on the returned value. Note the different value of transport and port in the example here:

    ---
    - name: Get Juniper Device Facts
      hosts: "junos_devices"
      gather_facts: false
      connection: local

      vars:
        netconf:
          host: "{{ ansible_host }}"
          username: "{{ username }}"
          password: "{{ password }}"
          port: 830
          transport: netconf

      tasks:
        - name: collect default set of facts
          junos_facts:
            provider: "{{ netconf }}"

          register: output

        - name: show output
          debug:
            var: output

When executed, you will receive this output from the Juniper device:
