Ansible:“这个模块需要键=值参数"；当提供 key=value 参数时 [英] Ansible: "this module requires key=value arguments" when key=value args supplied

问题描述

我从 Ansible 1.9.4 收到此错误:

I'm getting this error from Ansible 1.9.4:

TASK: [rabbitmq | add rabbitmq vhost] *****************************************
failed: [prod-sensu01] => (item={'name': u'/sensu'})
    => {"failed": true, "item": {"name": "/sensu"}}
msg: this module requires key=value arguments
(['name:', '/sensu', 'node:', 'rabbit',
  'tracing:', 'no', 'state:', 'present'])

但是从错误信息中可以看出，该项目实际上是一个键=值参数(哈希).

But as you can see from the error message, the item is actually a key=value argument (hash).

这里是变量:

# playbooks/roles/rabbitmq/vars/main.yml
# Set the rabbitmq vhost
rabbitmq_vhost_definitions:
  - name: "{{ sensu_server_rabbitmq_vhost }}"

以及角色的任务:

# playbooks/roles/rabbitmq/tasks/vhost.yml
- name: add rabbitmq vhost
  rabbitmq_vhost: >
    name: "{{ item.name }}"
    node: "{{ item.node | default('rabbit') }}"
    tracing: "{{ item.tracing | default('no') }}"
    state: present
  with_items: rabbitmq_vhost_definitions

这里发生了什么?

推荐答案

作为字符串传递的 Ansible 模块参数的键/值对应该用 = 分隔，而不是 :.正确的任务应该是这样的:

Key/value pairs of arguments for Ansible module passed as string should be separated by =, not by :. Correct task should look like this:

 # playbooks/roles/rabbitmq/tasks/vhost.yml
 - name: add rabbitmq vhost   
   rabbitmq_vhost: >
     name="{{ item.name }}"
     node="{{ item.node | default('rabbit') }}"
     tracing="{{ item.tracing | default('no') }}"
     state=present   
   with_items: rabbitmq_vhost_definitions

为什么它们作为字符串传递?因为您在模块名称后使用折叠块标量 >，所以在这一行:

Why they're passed as string? Because you're using folded block scalar > after name of the module, in this line:

rabbitmq_vhost: >

如果此模块支持两种传递参数的方式，您也可以尝试删除 > 标量(并保留冒号).

You could also try to remove > scalar (and leave colons) if this module supports both ways of passing arguments.
