The Jinja2 template

Let's also modify the playbook accordingly. In chapter8_8.yml, we will make the following changes:

1. Change the source file to nxos.j2
2. Change the destination file to be a variable
3. Provide the variable values as a dictionary that we will substitute in the template:

    ---
    - name: Template Looping
      hosts: localhost

      vars:
        nexus_devices: {
          "nx-osv-1": {"hostname": "nx-osv-1", "username": "cisco", 
    "password": "cisco"}
        }

      tasks:
        - name: create router configuration files
          template:
            src=./nxos.j2
            dest=./{{ item.key }}.conf
          with_dict: "{{ nexus_devices }}"

After running the playbook, you will find the destination file called nx-osv-1.conf with the values filled in and ready to be used:

$ cat nx-osv-1.conf
hostname nx-osv-1

feature telnet
feature ospf
feature bgp
feature interface-vlan

username cisco password cisco role network-operator
