ANSIBLE Routers Cisco

En este laboratorio vamos a usar ansible para sacar el backup de los routers y guardarlo en una carpeta (/bakups)

1. Instalacion de ansible

sudo apt update

sudo apt install software-properties-common

sudo apt-add-repository --yes --update ppa:ansible/ansible

sudo apt install ansible

2. Crear  el archivo de configuracion de ansible

tutorial@tutorial:~/myproject$ cat ansible.cfg
[defaults]
inventory      = ./hosts.cfg

3. Creacion del archivo de inventario (hosts.cfg)

tutorial@tutorial:~/myproject$ cat hosts.cfg
[all:vars]
ansible user=tutorial
ansible_ssh_pass=tutorial
ansible_network_os=ios
ansible_connection=network_cli

[Routers]
R1 ansible_host=1.1.1.1
R2 ansible_host=2.2.2.2
R3 ansible_host=3.3.3.3

4 Creacion de playbook

tutorial@tutorial:~/myproject$ cat backup.yml
---
- name: Backup
  hosts: Routers
  gather_facts: False
  connection: local
  tasks:
          - name: Show run
            ios_command:
                    commands:
                        - show run
            register: config

          - name: save output
            copy:
                    content: "{{config.stdout[0]}}"
                    dest: "./backups/{{inventory_hostname}}-config.txt"

5. Ejecucion del playbook

tutorial@tutorial:~/myproject$ ansible-playbook backup.yml

PLAY [Backup] ******************************************************************

TASK [Show run] ****************************************************************


TASK [save output] *************************************************************

R3                         : ok=2    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

6. Mostrar backups de configuraciones


tutorial@tutorial:~/myproject$ ls -al backups/
