Ansible Query, как сделать запрос внутри вывода JSON

/ 11 июня 2018

Я прошу URL API и перехожу к выводу в регистр.Это должен быть вывод в формате JSON.Первая переменная "vcclust" JSON, я могу извлечь "item.cluster", так как это всего лишь один уровень, плохо выглядит второй вывод "vchosts", я не могу разобрать, чтобы получить из него "item.name" и получить имена хостов

Это код: 

- hosts: localhost
  gather_facts: False
  vars_prompt:
  - name: "vcenter_hostname"
    prompt: "Enter vcenter hostname"
    private: no
  - name: "vcenter_user"
    prompt: "Enter vcenter username"
    private: no
  - name: "vcenter_pass"
    prompt: "Enter vcenter password"
    private: yes
  - name: "cluster_touched"
    prompt: "Enter cluster name"
    private: no

  tasks:
  - name: Login in to vCenter and store login information
    uri:
      url: "https://{{ vcenter_hostname }}/rest/com/vmware/cis/session"
      force_basic_auth: yes
      method: POST
      user: '{{ vcenter_user }}'
      password: '{{ vcenter_pass }}'
      status_code: 200
      validate_certs: no
    register: login
  - name: Get vCenter cluster ID for {{ cluster_touched }}
    uri:
      url: "https://{{ vcenter_hostname }}/rest/vcenter/cluster?filter.names={{ cluster_touched }}"
      force_basic_auth: yes
      validate_certs: no
      headers:
        Cookie: '{{ login.set_cookie }}'
    register: vcclust
  - name: Get ESXi nodes from cluster ID for {{ cluster_touched }}
    uri:
      url: "https://{{ vcenter_hostname }}/rest/vcenter/host?filter.clusters={{ item.cluster }}"
      force_basic_auth: yes
      validate_certs: no
      headers:
        Cookie: '{{ login.set_cookie }}'
    register: vchosts
    with_items:
    - '{{ vcclust.json.value }}'
  - name: Modify root local user to ESXi
    vmware_local_user_manager:
      hostname: '{{ item.name }}'
      username: root
      password: '{{ esxi_pass }}'
      local_user_name: root
      local_user_password: '{{ esxi_new_pass }}'
      validate_certs: False
    with_items:
    - '{{ vchosts.json.value }}'

И это результат отладки vchosts и vcclust

Я получил ошибку:

Большое спасибо @Kelson Silva

Вы указали ключ к ответу.

Я не знаю, почему это 

- debug: var=item.name
    with_items:
    -  "{{ vchosts.json.value }}"

не совпадает с 

- debug: 
    var: item.name
    with_items:
    -  "{{ vchosts.json.value }}"

и на самом деле это сводило меня с ума, это наверняка ошибка в этой версии ansible

проблема в том, что она перетаскивала элементы в моем первом запросе как список внутри Jsonи вам нужно перечислить их.

Чтобы не получить грязный JSON "vchosts", вам нужно использовать только один элемент из "vcclust", поэтому код заканчивается следующим образом: 

  - name: Get vCenter cluster ID for {{ cluster_touched }}
    uri:
      url: "https://{{ vcenter_hostname }}/rest/vcenter/cluster?filter.names={{ cluster_touched }}"
      force_basic_auth: yes
      validate_certs: no
      headers:
        Cookie: '{{ login.set_cookie }}'
    register: vcclust

  - name: Get ESXi nodes from cluster ID for {{ cluster_touched }}
    uri:
      url: "https://{{ vcenter_hostname }}/rest/vcenter/host?filter.clusters={{ vcclust.json.value[0].cluster }}"
      force_basic_auth: yes
      validate_certs: no
      headers:
        Cookie: '{{ login.set_cookie }}'
    register: vchosts

  - name: Modify root local user to ESXi
    vmware_local_user_manager:
      hostname: '{{ item.name }}'
      username: root
      password: '{{ esxi_pass }}'
      local_user_name: root
      local_user_password: '{{ esxi_new_pass }}'
      validate_certs: False
    with_items:
    -  "{{ vchosts.json.value }}"

Попробуйте использовать json_query.Для этого вам может потребоваться установить jmespath на вашем хосте.Вы можете сделать это с pip install jmespath. 

 - name: Get ESXi nodes from cluster ID for {{ cluster_touched }}
    uri:
      url: "https://{{ vcenter_hostname }}/rest/vcenter/host?filter.clusters={{ item.cluster }}"
      force_basic_auth: yes
      validate_certs: no
      headers:
        Cookie: '{{ login.set_cookie }}'
    register: vchosts
    with_items: "{{ vcclust | json_query('*.value') }}"

  - name: Modify root local user to ESXi
    vmware_local_user_manager:
      hostname: '{{ item.name }}'
      username: root
      password: '{{ esxi_pass }}'
      local_user_name: root
      local_user_password: '{{ esxi_new_pass }}'
      validate_certs: False
    with_items: "{{ vchosts.results | json_query('*.value') }}"
...
