How to Loop Over Dictionaries in Ansible

Ansible Tip:

Use the dict2items filter to loop over dictionaries in Ansible.

Here's an example:

---
- name: Example of dict2items filter
  hosts: localhost
  gather_facts: false

  vars:
    interfaces:
      eth0:
        ip: "192.168.1.1/24"
      eth1:
        ip: "192.168.2.1/24"

  tasks:
    - ansible.builtin.debug:
        msg: |
          Interface: {{ item.key }}
          IP Address: {{ item.value.ip }}
      loop: "{{ interfaces | dict2items }}"
# Output:
# ok: [localhost] => (item={'key': 'eth0', 'value': {'ip': '192.168.1.1/24'}}) => 
#   msg: |-
#     Interface: eth0
#     IP Address: 192.168.1.1/24
# ok: [localhost] => (item={'key': 'eth1', 'value': {'ip': '192.168.2.1/24'}}) => 
#   msg: |-
#     Interface: eth1
#     IP Address: 192.168.2.1/24
