In my machines , 4 pvc are created. Now i need to get all volume name associated with the pvc in a list. Then those list will be passed to storage array and i will ensure that the volumes are created in storage server.
- name: Verify whether the PVC is created
command: "kubectl get pvc pvc{{local_uuid}}-{{item}} -o json"
with_sequence: start=1 end=4
register: result
- set_fact:
pvcstatus: "{{ (item.stdout |from_json).status.phase }}"
volume_name: "{{(item.stdout |from_json).spec.volumeName}}"
with_items: "{{ result.results}}"
- debug: var=volume_name
But when i run the above tasks , volume_name is having last volumename alone instead of all the volumes as a list. How to get all the volume names in a list?
Your set_fact task is setting volume_name to a single value in each iteration...so of course, when the loop completes, the variable has the value from the final iteration. That's the expected behavior. If you want a list, you need to create a list. You can do this by appending to a list in your set_fact loop:
- set_fact:
volume_name: "{{ volume_name|default([]) + [(item.stdout |from_json).spec.volumeName] }}"
with_items: "{{ result.results}}"The expression volume_name|default([]) will evaluate to an empty list when volume_name is undefined (which is the case on the first iteration of the loop).
I tested this out using the following playbook:
---
- hosts: localhost
gather_facts: false
vars:
result:
results:
- stdout: '{"spec": {"volumeName": "volume1"}}'
- stdout: '{"spec": {"volumeName": "volume2"}}'
- stdout: '{"spec": {"volumeName": "volume3"}}'
tasks:
- debug:
var: result
- set_fact:
volume_name: "{{ volume_name|default([]) + [(item.stdout |from_json).spec.volumeName] }}"
with_items: "{{ result.results}}"
- debug:
var: volume_nameWhich results in:
TASK [debug] *****************************************************************************************************************************************************************
ok: [localhost] => {
"volume_name": [
"volume1",
"volume2",
"volume3"
]
}
