Ansible

Question

我在 Consul 上有一个 json 内容，我将其导入到我的剧本中。 json 包含帐户名和密码：

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

将其注册到变量后，我希望能够使用每个用户名和密码。由于这些 json 可能包含不同数量的条目，我希望我可以为此使用 with_items。有人可以帮我吗？

调试整个 json 没有问题：

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

我尝试获取个人条目（用户名和密码）。我试过下面的代码，但它只返回用户名：

- 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"
}

地图数据不可通过可靠循环迭代。

看看 dict2items 过滤器。

#!/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 }}"

Answer 2

to use every user name and password

下图

vars:
  accountsDataFromConsul:
    data:
      Value:
        account_1: password_1
        account_2: password_2
        account_3: password_3
tasks:
  - debug:
      msg: "key: {{ item.key }} value: {{ item.value }}"
    loop: "{{ accountsDataFromConsul.data.Value|dict2items }}"

给出（删节）：

"msg": "key: account_1 value: password_1"
"msg": "key: account_3 value: password_3"
"msg": "key: account_2 value: password_2"

Answer 3

谢谢弗拉基米尔和尼克。这非常有效。我唯一要做的就是在我的 Consul 输出中使用 from_json。

- set_fact:
    jsonvar: "{{accountsDataFromConsul.data.Value | from_json}}"

- debug:
    msg: "{{ item.key }} {{ item.value }}"
  loop: "{{jsonvar | dict2items}}"
