Ansible - using json imported from Consul

Question

I have a json content on Consul that I import to my playbook. The json contains account names and passwords:

{
    "account_1": "password_1",
    "account_2": "password_2",
    "account_3": "password_3"
}

After registering it to variable I wish to be able to use every user name and password. Since these jsons may contain different numbers of entries, I was hoping I could use with_items for this. Can someone help me out?

Debugging the whole json works with no issues:

TASK [debug] **************************************************************************
ok: [localhost] => {
    "accountsDataFromConsul.data.Value": {
        "account_1": "password_1",
        "account_2": "password_2",
        "account_3": "password_3"
    }
}

I try to get to individual entries (user names and passwords). I tried the below code, but it returned only user names:

- debug:
    var: item
  with_items: "{{accountsDataFromConsul.data.Value}}"

TASK [debug] ******************************************************************************
ok: [localhost] => (item=account_1) => {
    "item": "account_1"
}
ok: [localhost] => (item=account_2) => {
    "item": "account_2"
}
ok: [localhost] => (item=account_3) => {
    "item": "account_3"
}

Map data is not iterable via ansible loops.

Take a look at the dict2items filter.

#!/usr/bin/env ansible-playbook
- name: Lets munge some data
  hosts: localhost
  gather_facts: false
  become: false
  vars:
    my_dict:
      key_one: value_one
      key_two: value_two
    my_json: '{"key_one": "value_one", "key_two": "value_two"}'
  tasks:
  - name: Iterate over a dict
    debug:
      msg: "{{ item.key }} {{ item.value }}"
    loop: "{{ my_dict | dict2items }}"

  - name: Iterate over json
    debug:
      msg: "{{ item.key }} {{ item.value }}"
    loop: "{{ my_json | from_json | dict2items }}"
