The Ansible Arista example

The final playbook example we will look at will be the Arista command module. At this point, we are quite familiar with our playbook syntax and structure. The Arista device can be configured to use transport using cli or eapi, so, in this example, we will use cli.

This is the host file:

[eos_devices]
A1 ansible_host=192.168.199.158

The playbook is also similar to what we have seen previously:

    ---
- name: EOS Show Commands
hosts: "eos_devices"
gather_facts: false
connection: local

vars:
cli:
host: "{{ ansible_host }}"
username: "arista"
password: "arista"
authorize: true
transport: cli

tasks:
- name: eos show commands
eos_command:
commands:
- show version | i Arista
provider: "{{ cli }}"
register: output

- name: show output
debug:
var: output

The output will show the standard output as we would expect...
