Trying to get a variable defined when the task is partially failed/ignored. When a VM is not found in Vsphere it throws an error: "msg": "Unable to gather information for non-existing VM vm2"
I tried with and without ignore_errors: True and failed_when: 0 > 1 but no change.
I need the variable vm_fact to be defined even when a non-existing VM is in the decom_list. The plan is to change the list after i have identified which VM's are non-existing.
Please note: this task does work when all vm's are present in the system. When one is missing the task fails. I need the task not to fail so that i can clean the decom_list and then run it again.
- name: check/power(on/off) hosts on vsphere
hosts: localhost
ignore_errors: True
vars:
decom_list:
- vm1
- vm2
- vm3
tasks:
- name: check hosts on vsphere
vmware_guest_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
name: "{{ item }}"
schema: vsphere
datacenter: DC1
loop: "{{ decom_list }}"
register: vm_fact
ignore_errors: True
failed_when: 0 > 1
Whatever i try does not work because my vm_fact is not defined.
- debug:
var: "{{ vm_fact }}"
error:
TASK [debug] **************************************************************************************************************************
ok: [localhost] => {
"<class 'dict'>": "VARIABLE IS NOT DEFINED!"
}
Just to confirm i did try all i know.
When i try it with a loop:
- debug:
var: "{{ item['item'] }}"
loop: "{{ vm_fact['results'] }}"
when: '"Unable to gather information for non-existing VM" in item.msg'
I get error:
