Question

所以我的剧本中有以下部分：

- name: Loop hash
  set_fact:
   "{{ item.key }}":
      instance_id: "{{ item.value.ansible_ec2_instance_id }}"
      instance_az: "{{ item.value.ansible_ec2_placement_availability_zone }}"
  with_dict: "{{ hostvars }}"
  when: (item.value.ansible_ec2_instance_id is defined) and
        (item.value.ansible_ec2_placement_availability_zone is defined)

当我检查输出时，它没有解析item.key

'item.key': {'instance_id': u'i-abc12345678', 'instance_az': u'ap-southeast-2b'}

关于最新进展的任何想法？

错误建议的解决方案：

ERROR: Syntax Error while loading YAML script, /apps/co-playbooks/common/tasks/elb_check_instances.yml
Note: The error may actually appear before this position: line 40, column 18

   { "{{ item.key }}":
      instance_id: "{{ item.value.ansible_ec2_instance_id }}"
                 ^
We could be wrong, but this one looks like it might be an issue with
missing quotes.  Always quote template expression brackets when they
start a value. For instance:

尝试了不同的语法：

- name: Loop hash
  set_fact:
   { "{{ item.key }}":
      { instance_id: "{{ item.value.ansible_ec2_instance_id }}",
        instance_az: "{{ item.value.ansible_ec2_placement_availability_zone }}" }}

  with_dict: "{{ hostvars }}"
  when: (item.value.ansible_ec2_instance_id is defined) and
        (item.value.ansible_ec2_placement_availability_zone is defined)

仍无法解析item.key

'{# item.key #}': {'instance_id': u'i-abc1234567', 'instance_az': u'ap-southeast-2b'}

在set_fact任务之外添加一对{ }。

- name: Loop hash
  set_fact:
   { "{{ item.key }}":
      instance_id: "{{ item.value.ansible_ec2_instance_id }}"
      instance_az: "{{ item.value.ansible_ec2_placement_availability_zone }}" }
  with_dict: "{{ hostvars }}"
  when: (item.value.ansible_ec2_instance_id is defined) and
        (item.value.ansible_ec2_placement_availability_zone is defined)

ansible 1.8不解析set_facts中的item.key
