I’m pretty new to ansible and I’m not sure how to get it right.
To start with, I have implemented this dictionnary var for an exemple. There is 2 values but it could be a greater number:

tf_ETCD:
  1:
    hostname: Etcd01
    ip: 192.168.1.141
  2:
    hostname: Etcd02
    ip: 192.168.1.142

I’d like the result to be formatted like that :

{{ tf_ETCD1_Host }}=https://{{ tf_ETCD1_IP }}:2380,{{ tf_ETCD2_Host }}=https://{{ tf_ETCD2_IP }}:2380

So I kidda get it by looping over the list via this code:

    - name: Format each values
      set_fact:
        etcd: "{{ item.value.hostname }}=https://{{ item.value.ip }}:2380,"
      loop: "{{ lookup('ansible.builtin.dict', tf_ETCD) }}"
      register: etcd_query
    - name: Examine the joined string
      debug:
        msg: "{{ etcd_query['results'][0]['ansible_facts']['etcd'] }}{{ etcd_query['results'][1]['ansible_facts']['etcd'] }}"

The result gave me :

TASK [Format each values] **********************************************************************************************
ok: [] => (item={'key': 1, 'value': {'hostname': 'Etcd01', 'ip': '192.168.1.141'}})
ok: [] => (item={'key': 2, 'value': {'hostname': 'Etcd02', 'ip': '192.168.1.142'}})

TASK [Examine the joined string] ***************************************************************************************
ok: [] => {
    "msg": "Etcd01=https://192.168.1.141:2380,Etcd02=https://192.168.1.142:2380,"
}

I cannot figure out how to do a “foreach loop result” in my “Examine the joined string” play.

If you can give me a hint or the concept I’m looking for, you’ll save my day.
