我对 Ansible 还很陌生，我不知道如何正确使用它。
首先，我以实现这个字典 var 为例。有 2 个值，但可以是更大的数字：
tf_ETCD:
1:
hostname: Etcd01
ip: 192.168.1.141
2:
hostname: Etcd02
ip: 192.168.1.142
我希望结果的格式如下：
{{ tf_ETCD1_Host }}=https://{{ tf_ETCD1_IP }}:2380,{{ tf_ETCD2_Host }}=https://{{ tf_ETCD2_IP }}:2380
所以我通过以下代码循环列表来得到它：
- name: Format each value
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'] }}"
结果给了我：
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,"
}
我无法弄清楚如何在“检查连接的字符串”游戏中执行“foreach 循环结果”。
如果您能给我一个提示或我正在寻找的概念，您将拯救我。

- hosts: localhost
become: false
gather_facts: false
vars:
tf_ETCD:
1:
hostname: Etcd01
ip: 192.0.2.1
2:
hostname: Etcd02
ip: 192.0.2.2
tasks:
- debug:
msg: "{{ tf_ETCD[ansible_loop.index] }}"
loop: "{{ range(0, tf_ETCD | length, 1) | list }}"
loop_control:
extended: true
- set_fact:
etcd: "{{ etcd | d('') + tf_ETCD[ansible_loop.index].hostname ~ '=https://' ~ tf_ETCD[ansible_loop.index].ip ~ ':2380,' }}"
loop: "{{ range(0, tf_ETCD | length, 1) | list }}"
loop_control:
extended: true
- debug:
msg: "{{ etcd }}"
将产生
