Hi All,
I have a playbook as follows:
---
- hosts: all
gather_facts: no
ignore_unreachable: true
tasks:
- command: "{{ item }}"
loop:
- "ls"
- "df -h"
register: files
ignore_errors: true
- name: delegate
command: ls
register: files2
delegate_to: "{{item}}"
ignore_errors: true
with_items:
- "{{groups['test_servers1']}}"
- lineinfile:
line: "{{ item.stdout }}"
path: /tmp/list.log
create: yes
when:
- item.changed is defined
- item.changed
loop: "{{ files.results +
files2.results}}"
TEST1: my inventory looks as follows:
192.168.153.31
#[test_servers1]
output:
TASK [command]
**************************************************************** changed:
[192.168.153.31] => (item=ls) changed: [192.168.153.31] => (item=df -h)
TASK [delegate]
*****************************************************************************
fatal: [192.168.153.31]: FAILED! => {"msg": "'dict object' has no attribute
'test_servers1'"} ...ignoring TASK [lineinfile]
***************************************************************** skipping:

TEST2: inventory as follows:
192.168.153.31
[test_servers1]
Output:

******************************************************************

*Question1*: In TEST1 since inventory doesn't contain test_servers1 group,
so task is ignored. but why lineinfile is skipped eventhought file variable
contain results?
*Question2*: In TEST2, my delegate task contains only one command i.e.,
*ls *why file2 has results? As per my knowledge when looping through
multiple commands only register variable contains results.
*Question3*: In lineinfile module, Is it possible to check files2 contains
results and
if yes to check files2.results is not empty then only loop through it
otherwise skip it?
someone please clarify my doubts. Thanks in Advance.
Thanks,
BHR.
