Question

此前已在Stack上回答过这个问题。

ansible get aws ebs volume id which already exist

Get volume id from newly created ebs volume using ansible

对于我的生活，我正在尝试ec2_vol.volume_id和其他一些jmespath查询位，但没有得到正确的输出帮助。我只想要卷号。没什么。

 - hosts: localhost
   connection: local
   gather_facts: no
   tasks:
   - name: get associated vols
     ec2_vol:
       instance: i-xxxxxxxxxxxxx
       state: list
       profile: default
       region: us-east-1
     register: ec2_vol

   - debug:
       msg: "{{ ec2_vol.volume_id }}"

也不起作用

 - hosts: localhost
   connection: local
   gather_facts: no
   tasks:
   - name: get associated vols
     ec2_vol:
       instance: i-xxxxxxxxxxxxxx
       state: list
       profile: default
       region: us-east-1
     register: ec2_vol

   - debug: msg="{{ item.volume_id }}"
     with_items: ec2_vol.results

Ansible 2.2和2.3测试

Answer 1

从先前的答案中取出一些内容，您需要了解JMESPATH，例如过滤，以便从输出中获得您想要的内容。

以下是答案

---
 - hosts: localhost
   connection: local
   gather_facts: no
   tasks:
   - name: get associated vols
     ec2_vol:
       instance: i-xxxxxxxxxxxxxx
       state: list
       profile: default
       region: us-east-1
     register: ec2_vol

   - debug: msg="{{ ec2_vol.volumes | map(attribute='id') | list }}"
