I have the following in my tasks/main.yml
Enter code here.- name: Check if NetworkManager is running
shell: "systemctl status NetworkManager"
register: nm_status
changed_when: false
ignore_errors: yes
when: ansible_distribution_major_version == '7'
- name: debug
debug:
var: nm_status.stdout
For one particular server (cent7) the stdout is as follows:
Enter codok: [cent7] => {

e here...
I call the handler(s) through "Networking"
My handlers/main.yml currently is as follows:
Enter code here...---
# handlers file for dns_update
- name: Networking
debug:
changed_when: true
notify:
- 6 network restart
- 7 network restart
- 7 NetworkManager restart
- name: ensure stopped
service:
name: NetworkManager
state: stopped
- name: 6 network restart
service:
name: network
state: restarted
when: ansible_distribution_major_version == '6' and not
ansible_distribution_major_version == '7'
- name: 7 network restart
service:
name: network
state: restarted
when: (ansible_distribution_major_version == '7') and
('"NetworkManager.service;
disabled" in nm_status.stdout')
notify: ensure stopped
- name: 7 NetworkManager restart
service:
name: NetworkManager
state: restarted
when: (ansible_distribution_major_version == '7') and
('"NetworkManager.service;
disabled" not in nm_status.stdout')
The reason for 3 different network restarts is to handle cent/rhel{6,7}
servers. Some of the version 7 boxes have NetworkManager running, and some
do not
Results for my cent7 box:
RUNNING HANDLER [dns_update : Networking]
************************************************************************************************************************************************************************************************
ok: [cent7] => {
"msg": "Hello world!"
}
RUNNING HANDLER [dns_update : 6 network restart]
*****************************************************************************************************************************************************************************************
skipping: [cent7]
RUNNING HANDLER [dns_update : 7 network restart]
*****************************************************************************************************************************************************************************************
changed: [cent7]
RUNNING HANDLER [dns_update : 7 NetworkManager restart]
**********************************************************************************************************************************************************************************
changed: [cent7]
RUNNING HANDLER [dns_update : ensure stopped]
********************************************************************************************************************************************************************************************
changed: [cent7]
I expected it to only run "7 network restart" and "ensure stopped"
I only have the "ensure stopped" in there because the former seems to be
starting NetworkManager despite being disabled. In addition, I don't know
why "7 NetworkManager restart" is executing as the nm_status.stdout DOES
contain "NetworkManager.status disabled;"
I must be missing something, have a syntax error, or am encountering some
sort of a bug. I would appreciate any feedback.
