问题
I used ansible's ec2_vol module to create an ebs volume. I saw the source code and found that it internally calls create_volume() method of boto with user specified parameters. I want to register the return value of ec2_vol module and get the volume_ids of newly created volumes.
As of now my playbook looks like
- 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
I would like to know how to get the volume ids of newly created volumes. I saw that run_instances() method's return object has an attribute instances whcih contain a list of instances. But I couldn't find any proper documentation of create_volume() method's return value.
Any help is appreciated.
Thanks,

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
