Hii
If you
1. Properly format your playbook to be a list of plays
2. Use shell
3. Don't use {{ }} around the var in your debug task
Then it works:
TASK [get file server's IP address]
****************************************************************
changed: [villa -> localhost]
TASK [debug]
***************************************************************************************
ok: [villa] =>
fs_ip_addr:
changed: true
cmd: grep prod-fs1 /etc/hosts | awk '{ print $0 }'
delta: '0:00:00.008973'
end: '2020-03-04 00:36:05.873228'
failed: false
rc: 0
start: '2020-03-04 00:36:05.864255'
stderr: ''
stderr_lines: []
stdout: 10.10.10.20 prod-fs1
stdout_lines:
- 10.10.10.20 prod-fs1
But I would also recommend:
4. Dropping privilege escalation for local actions
5. Use "print $1" as this will match the actual IP
6. Use 'stdout' sa this will be the actual IP
Thus the playbook would be:
---
- hosts: all
gather_facts: yes
become: yes
pre_tasks:
- name: get file server's IP address
shell: "grep prod-fs1 /etc/hosts | awk '{ print $1 }'"
register: fs_ip_addr
become: no
delegate_to: localhost
- debug: var=fs_ip_addr.stdout
And then output would be:
TASK [debug]
***********************************************************************************************
ok: [villa] =>
fs_ip_addr.stdout: 10.10.10.20
Although shell+grep+awk still sounds fragile
