使用Ansible从新创建的ebs卷中获取卷ID [英] Get volume id from newly created ebs volume using ansible

问题描述

我使用ansible的ec2_vol模块创建了ebs卷.我看到了源代码，发现它在内部使用用户指定的参数调用boto的create_volume()方法.我想注册ec2_vol模块的返回值并获取新创建的卷的volume_ids.

到目前为止，我的剧本看起来像

- name: Attach a volume to previously created instances
  local_action: ec2_vol instance={{item.id}} volume_size=5 aws_access_key={{aa_key}} aws_secret_key={{as_key}} region={{region}}
  with_items: ec2.instances
  register: ec2_volumes
  ignore_errors: yes

- name: Stop the instances
  local_action: command aws ec2 stop-instances --profile=xervmon --instance-id={{item.id}}
  with_items: ec2.instances
  ignore_errors: yes

- name: Detach volume from instances
  local_action: command aws ec2 detach-volume --profile=xervmon --volume-id=????                                                
  ignore_errors: yes

我想知道如何获取新创建的卷的卷ID.我看到run_instances()方法的返回对象具有一个实例实例，其中包含实例列表.但是我找不到关于create_volume()方法返回值的任何适当文档.

感谢您的帮助.

谢谢

根据 解决方案

According to the ec2_vol module source code, the module returns:

• volume_id
• device

In your case, you are creating multiple volumes via with_items, so the ec2_volumes variable that you register will be a dictionary with a key named results that holds the list of results from each of the individual ec2_vol invocations.

Here's an example that prints out the volume ids (warning: I haven't tested this).

- name: Attach a volume to previously created instances
  local_action: ec2_vol instance={{item.id}} volume_size=5 aws_access_key={{aa_key}} aws_secret_key={{as_key}} region={{region}}
  with_items: ec2.instances
  register: ec2_volumes

- name: Print out the volume ids
  debug: msg={{ item.volume_id }}
  with_items: ec2_volumes.results
