Jinja2 loops

We can also loop through a list as well as a dictionary as we have completed in the last section; make the following changes in nxos.j2:

    {% for vlan_num in item.value.vlans %}    vlan {{ vlan_num }}    {% endfor %}    {% for vlan_interface in item.value.vlan_interfaces %}    interface {{ vlan_interface.int_num }}      ip address {{ vlan_interface.ip }}/24    {% endfor %}

Provide the additional list and dictionary variables in the playbook:

    vars:     nexus_devices: {       "nx-osv-1": {       "hostname": "nx-osv-1",       "username": "cisco",       "password": "cisco",       "vlans": [100, 200, 300],       "vlan_interfaces": [          {"int_num": "100", "ip": "192.168.10.1"},          {"int_num": "200", "ip": "192.168.20.1"},          {"int_num": "300", "ip": "192.168.30.1"}        ]       }     }

Run the playbook, and you will ...
