Iterating in a with_items loop ansible - amazon-web-services

Question

Hi there i am atm trying to get the hang of ansible with aws and i am really likeing the flexibility of it so far.
Sadly now i am starting to hit a brick wall with my experiments. I am trying to tag volumes for specific instances that have the tag environment: test with the tages environment: test and backup: true . The playbook is working as intended if i specify every single Index of the array in the with_items loop. Here's my playbook so far:
---
- name: Tag the EBS Volumes
hosts: tag_environment_test
gather_facts: False
tags: tag
vars_files:
- /etc/ansible/vars/aws.yml
tasks:
- name: Gather instance instance_ids
local_action:
module: ec2_remote_facts
region: '{{ aws_region }}'
filters:
instance-state-name: running
"tag:environment": test
register: test_id
- name: Gather volume information for instance
local_action:
module: ec2_vol
region: '{{ aws_region }}'
instance: "{{ item.id }}"
state: list
with_items:
- "{{ test_id.instances }}"
register: ec2_volumes
- debug:
var: ec2_volumes
- name: Do some actual tagging
local_action:
module: ec2_tag
region: '{{ aws_region }}'
resource: "{{ item.id }}"
args:
tags:
environment: test
backup: true
with_items:
- "{{ ec2_volumes.results[0].volumes }}"
# - "{{ ec2_volumes.results[1].volumes }}"
My question now is it possible to iterate over the full array in ec2_volumes.results without having the need to specify every single value in the array. Like for example _ec2_volumes.results[X].volumes X=X+1_ so every time he goes through the loop he iterates +1 until the end of the array.
Every Input also on the rest of the playbook would be very appriciated (like i said still trying to get the hang of ansible. :)

You can iterate over your list of results:
- name: Do some actual tagging
delegate_to: localhost
ec2_tag:
region: '{{ aws_region }}'
resource: "{{ item.volume.id }}"
tags:
environment: test
backup: true
with_items: "{{ ec2_volumes.results }}"
Every Input also on the rest of the playbook would be very appreciated
Consider using delegate_to: localhost instead of local_action. Consider this task:
- name: an example
command: do something
Using delegate_to, I only need to add a single line:
- name: an example
delegate_to: localhost
command: do something
Whereas using local_action I need to rewrite the task:
- name: an example
local_action:
module: command do something
And of course, delegate_to is more flexible: you can use it to delegate to hosts other than localhost.
Update
Without seeing your actual playbook it's hard to identify the source of the error. Here's a complete playbook that runs successfully (using synthesized data and wrapping your ec2_tag task in a debug task):
---
- hosts: localhost
gather_facts: false
vars:
aws_region: example
ec2_volumes:
results:
- volume:
id: 1
- volume:
id: 2
tasks:
- name: Do some actual tagging
debug:
msg:
ec2_tag:
region: '{{ aws_region }}'
resource: '{{ item.volume.id }}'
tags:
environment: test
backup: true
with_items: "{{ ec2_volumes.results }}"
