Main Playbook

---
- hosts: junos
  gather_facts: yes
  connection: local
  ignore_errors: yes

  tasks:
  - name: obtain login credentials
    include_vars: ../auth/secrets.yml

  - name: define provider
    set_fact:
      provider:
        host: "{{ inventory_hostname }}"
        username: "{{ creds['username'] }}"
        password: "{{ creds['password'] }}"
        transport: netconf

  - name: obtain playbook variables
    include_vars: vars/play_vars.yml

  - name: Running task {{ task1 }}
    include: tasks/junos_config-{{ task1 }}.yml
    when: task1 is defined

  - name: Running task {{ task2 }}
    include: tasks/junos_config-{{ task2 }}.yml
    when: task2 is defined

Variable Task Control

The task is controlled by the task[#]: variable in vars/play_vars.yml. When vars/play_vars.yml is called by the variable task[#]: affects include: tasks/vyos_config-{{ task[#] }}.yml, thus running the needed task.
