Hello,
I understand this very basic, but I'm still learning... (And my apologies
for the long message.)
I built the playbook below so I can check which server is still in need of
an OS update based on its current kernel version:
---
- hosts: "{{ my_host }}"
remote_user: xxxxxx
vars:
server:
srvname: "{{ ansible_hostname }}"
kernel: "{{ ansible_kernel }}"
tasks:
- block:
- name: create list
set_fact:
serverlist: "{{ serverlist | default({}) | combine(
{item.srvname: item.kernel} ) }}"
with_items:
- "{{ server }}"
- name: print list
debug:
msg: "{{ serverlist }}"
- name: send list to file
lineinfile:
create: yes
line: "{{ serverlist | string }}"
path: "/shared/kernel.list"
when: (ansible_distribution == "OracleLinux") and
(hostvars[inventory_hostname].ansible_kernel !=
"4.18.0-305.10.2.el8_4.x86_64")
It's working, but I'd like to improve the way it presents the list of
servers in need of update... So, could you help with some hints on how I
could:
Make the "print list" task work in a way that instead of printing this:
TASK [print list]
**************************************************************************
ok: [xxxxxxxx] => {
"msg": {
"xxxxxxxxx": "4.18.0-240.10.1.el8_3.x86_64"
}
}
ok: [yyyyyyyy] => {
"msg": {
"yyyyyyyy": "4.18.0-240.10.1.el8_3.x86_64"
}
===> It would print something like (or closer to) this:
"msg": {
"xxxxxxxxx": "4.18.0-240.10.1.el8_3.x86_64'
"yyyyyyyy": "4.18.0-240.10.1.el8_3.x86_64
}
And, on the "send list to file" task, how would I have the file content
changed from this:
{'xxxxxxxxx ': '4.18.0-240.10.1.el8_3.x86_64'}
{' yyyyyyyy ': '4.18.0-240.10.1.el8_3.x86_64'}
===> To something like this:
xxxxxxxxx: 4.18.0-240.10.1.el8_3.x86_64
{yyyyyyyy: 4.18.0-240.10.1.el8_3.x86_64
I mean, without single quotes and curly braces.
I understand I could build another task to parse that file an "clean" it,
but, is there a way to do that while writing to the file?
Thanks a lot,
Alex
