Back in May of 2018 I asked "How to use group_vars when managed host is in
multiple groups
<https://groups.google.com/d/msg/ansible-project/Tzb_cNpytD0/fB-xDIRFBAAJ>?"
(see
https://groups.google.com/d/msg/ansible-project/Tzb_cNpytD0/fB-xDIRFBAAJ)
and Brian Coca present an excellent solution.
I've been using this solution since May 2018 but in the last 2 weeks I'm
seeing different behavior.
Here are the tasks:
- name: set chocolatey packages to remove
set_fact:
chocolatey_remove_packages: "{{
chocolatey_remove_packages|union(query('vars', item)) }}"
loop: "{{
hostvars[inventory_hostname]|select('match','.*chocolatey_remove_packages$')
| list }}"
tags: win_chocolatey
- debug:
msg: "{{ chocolatey_remove_packages }}"
tags: win_chocolatey
And the debug is below
"msg": [
[],
[
"ccleaner",
"cura",
"edrawings-viewer",
"edrawings-viewer-2018",
"malwarebytes",
"uninstalltool",
"veeam-endpoint-backup-free",
"edrawings-viewer"
],
[
"3cx",
"firefox"
]
]
I am pretty sure I used to get
"msg": [
[
"ccleaner",
"cura",
"edrawings-viewer",
"edrawings-viewer-2018",
"malwarebytes",
"uninstalltool",
"veeam-endpoint-backup-free",
"edrawings-viewer",
"3cx",
"firefox"
]
]
I think the empty list element is from the
role/win_chocolatey/vars/main.yml where I initialize
the chocolatey_remove_packages list and that never showed up until recently
---
# vars file for roles/win_chocolatey
# Initialize variable
#
chocolatey_remove_packages: []
And the
[
"ccleaner",
"cura",
"edrawings-viewer",
"edrawings-viewer-2018",
"malwarebytes",
"uninstalltool",
"veeam-endpoint-backup-free",
"edrawings-viewer"
],
Is from my corporate wide variable and
[
"3cx",
"firefox"
]
Is from my group_vars
So my question is did something change with union(query('vars', item))
when used with loop | list ?
I've tried loop | flatten(levels=1) no difference.
Things continue to work with unusual output.
TASK [win_chocolatey : remove old/deprecated packages (choco)]
*****************
ok: [appserver] => (item=[])
ok: [appserver] => (item=[u'ccleaner', u'cura', u'edrawings-viewer', u
'edrawings-viewer-2018', u'malwarebytes', u'uninstalltool', u
'veeam-endpoint-backup-free', u'edrawings-viewer'])
ok: [appserver] => (item=[u'3cx', u'firefox'])
Changing the task that actually removed the package to use
flatten(levels=1)
- name: remove old/deprecated packages (choco)
win_chocolatey:
name: "{{ item }}"
state: "absent"
when:
- chocolatey_remove_packages is defined
loop: "{{ chocolatey_remove_packages|flatten(levels=1) }}"
Givens me the output I've been used to.
Just looking for an explanation on what changed and where I missed this
change in behavior.
Thanks.
