Installing Identity Management
24.12. Using an Ansible playbook to uninstall an IdM server even if this leads to a disconnected topology

24.12. Using an Ansible playbook to uninstall an IdM server even if this leads to a disconnected topology

참고

In an existing Identity Management (IdM) deployment, replica and server are interchangeable terms.

Complete this procedure to uninstall an IdM replica using an Ansible playbook even if this results in a disconnected IdM topology. In the example, server456.idm.example.com is used to remove the replica and the associated host entry with the FQDN of server123.idm.example.com from the topology, leaving certain replicas disconnected from server456.idm.example.com and the rest of the topology.

참고

If removing a replica from the topology using only the remove_server_from_domain does not result in a disconnected topology, no other options are required. If the result is a disconnected topology, you must specify which part of the domain you want to preserve. In that case, you must do the following:

Specify the ipaserver_remove_on_server value.
Set ipaserver_ignore_topology_disconnect to True.

Prerequisites

On the control node:
- You are using Ansible version 2.15 or later.
- You have installed the ansible-freeipa package.
- The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
- The example assumes that the secret.yml Ansible vault stores your ipaadmin_password and that you have access to a file that stores the password protecting the secret.yml file.
The target node, that is the node on which the freeipa.ansible_freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.
On the managed node:
- The system is running on RHEL 10.

Procedure

Create your Ansible playbook file uninstall-server.yml with the following content:
```
---
- name: Playbook to uninstall an IdM replica
  hosts: ipaserver
  become: true

  roles:
  - role: freeipa.ansible_freeipa.ipaserver
    ipaserver_remove_from_domain: true
    ipaserver_remove_on_server: server456.idm.example.com
    ipaserver_ignore_topology_disconnect: true
    state: absent
```
참고
Under normal circumstances, if the removal of server123 does not result in a disconnected topology: if the value for ipaserver_remove_on_server is not set, the replica on which server123 is removed is automatically determined using the replication agreements of server123.

Uninstall the replica:

$ ansible-playbook --vault-password-file=password_file -v -i <path_to_inventory_directory>/hosts <path_to_playbooks_directory>/uninstall-server.yml

Ensure that all name server (NS) DNS records pointing to server123.idm.example.com are deleted from your DNS zones. This applies regardless of whether you use integrated DNS managed by IdM or external DNS.
