my playbook grabs show command output from a cisco switch and then
reformats that output into structured data thanks to a parsing script
written by someone smarter than me. i'm pretty new to ansible data
structures but I believe this data is a list (ios_vlans) of dictionary
objects (vlans) which contains multiple elements, including one that is
also a list (ports). here is sample data
# Schema Output
#--------------
#
# {
# "ansible_facts": {
# "ios_vlans": {
# "vlans": [
# {
# "id": 1,
# "name": "default",
# "ports": [
# "GigabitEthernet0/1",
# "GigabitEthernet0/2",
# "GigabitEthernet0/3",
# "GigabitEthernet1/0",
# "status": "active"
# },
# {
# "id": 200,
# "name": "vlan200",
# "ports": [
# ""
# ],
# "status": "active"
# },
# {
# "id": 300,
# "name": "vlan300",
# "ports": [
# ""
# ],
# "status": "active"
# }
# ]
# }
# },
#
I can see this data in its entirety by referencing ios_vlans. I can also
directly access elemets such as ios_vlans.vlans[1].id by calling them
explicitly. the problem is that I am unable to iterate through the data.
I've tried with_items and with_dict and get the error that 'items' is
undefined. here is the play:
---
- name: change port vlan
hosts: all
connection: local
gather_facts: no
vars:
vlan_parse_path: ./vlan-parser.yml
tasks:
- name: get vlan info
ios_command:
commands: show vlan
register: vlan_output
- name: generate fact from vlan output
set_fact:
ios_vlans: "{{vlan_output.stdout[0] | parse_cli(vlan_parse_path)}}"
- name: complete schema output
debug:
msg: "{{ios_vlans}}"
- name: first vlan in index
debug:
msg: "{{ios_vlans.vlans[0]}}"
- name: second vlan in index
debug:
msg: "{{ios_vlans.vlans[1]}}"
- name: output first vlan ID
debug:
msg: "{{ios_vlans.vlans[0].id}}"
- name: output all vlan IDs <<<<<<<this task fails
debug:
msg: "{{item.id}}"
with_items: "{{ios_vlans}}"
