How to delete a group in Linux with Ansible?
I'm going to show you a live Playbook with some simple Ansible code.
I'm Luca Berton and welcome to today's episode of Ansible Pilot
Ansible deletes a group account
ansible.builtin.group
- Add or remove groups
Today we're talking about the Ansible module group.
The full name is ansible.builtin.group, which means that is part of the collection of modules "builtin" with ansible and shipped with it.
It's a module pretty stable and out for years.
It adds or removes groups.
It supports a huge variety of Linux distributions and macOS.
It relies on three Linux commands: groupadd, groupdel and groupmod.
For Windows, use the ansible.windows.win_group module instead.
Parameters
- name string - group name
- state string - present/absent
- local string - "local" command alternatives
This module has some parameters to perform some tasks.
The only required is "name", which is the group name.
The "state" parameter allows us to create or delete a group, in our use case set to "absent" to delete a group.
The "local" parameter allows using the "local" command alternatives on platforms that implement it if you have a central authentication system.
## Playbook
Let's jump in a real-life Ansible Playbook to delete a group.
code
- group_delete.yml
``yaml
---
- name: group module Playbook
hosts: all
become: true
vars:
mygroup: "example"
tasks:
- name: delete group
ansible.builtin.group:
name: "{{ mygroup }}"
state: absent
`
execution
output
`bash
$ ansible-playbook -i Playbook/inventory group/delete.yml
PLAY [group module Playbook] **
TASK [Gathering Facts]
ok: [demo.example.com]
TASK [delete group] *
changed: [demo.example.com]
PLAY RECAP **
demo.example.com : ok=2 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
`
verification
``bash
$ ssh [email protected]
[devops@demo ~]$ sudo su
[root@demo devops]# getent group | grep example
[root@demo devops]# getent group
