Create a Dict key from a variable

[Spiro Mitsialis]

Hi, 

I hope I am using the right terminology here.

I'm trying to modify some cisco_ios facts.   I know how to use combine to merge the two together.  I'm having problems creating a list/dict that I can use to merge into the original dict 

The playbook is passed a variable called "port".  What I would like to create a fact as below

set_fact:
  temp_interface:
    "{{ port }}":
        name: "{{ port }}"
        description: free
        status: shutdown

This above does not work.  As an example port = GigabitEthernet1/0/10

The result from above is:

TASK [debug] *******************************************************************************************************************************************************************
ok: [switch-poc-sw8.gw.mcgill.ca] => {
    "temp_interface": {
        "{{ port_id }}": {
            "description": "free",
            "name": "GigabitEthernet1/0/10",
            "status": "shutdown"

        }
    }
}

How can this be accomplished.

Thanks

Try this

- set_fact:
temp_interface: "{{ temp_interface|
default({})|
combine({port: {'name': port,
'description': 'free',
'status': 'shutdown'}})
}}"

Works great!

Wish there was some good docs out there.
