This role allows to configure a new IPA server that is a replica of the server. Once it has been created it is an exact copy of the original IPA server and is an equal master. Changes made to any master are automatically replicated to other masters.
This can be done in different ways using auto-discovery of the servers, domain and other settings or by specifying them.
Note: The ansible playbooks and role require a configured ansible environment where the ansible nodes are reachable and are properly set up to have an IP address and a working package manager.
FreeIPA versions 4.6 and up are supported by the replica role.
Controller * Ansible version: 2.8+
Node Supported FreeIPA version (see above) Supported distribution (needed for package installation only, see above)
Example inventory file with fixed principal using auto-discovery with DNS records:
[ipareplicas] ipareplica1.example.com ipareplica2.example.com [ipareplicas:vars] ipaadmin_principal=admin
Example playbook to setup the IPA client(s) using principal from inventory file and password from an Ansible Vault file:
--- - name: Playbook to configure IPA replicas hosts: ipareplicas become: true vars_files: - playbook_sensitive_data.yml roles: - role: ipareplica state: present
Example playbook to unconfigure the IPA client(s) using principal and password from inventory file:
--- - name: Playbook to unconfigure IPA replicas hosts: ipareplicas become: true roles: - role: ipareplica state: absent
Example inventory file with fixed server, principal, password and domain:
[ipaserver] ipaserver.example.com [ipareplicas] ipareplica1.example.com ipareplica2.example.com [ipareplicas:vars] ipareplica_domain=example.com ipaadmin_principal=admin ipaadmin_password=MySecretPassword123 ipadm_password=MySecretPassword456
Example playbook to setup the IPA client(s) using principal and password from inventory file:
--- - name: Playbook to configure IPA replicas with username/password hosts: ipareplicas become: true roles: - role: ipareplica state: present
The playbooks needed to deploy or undeploy a replica are part of the repository in the playbooks folder. There are also playbooks to deploy and undeploy clusters.
install-replica.yml uninstall-replica.yml
Please remember to link or copy the playbooks to the base directory of ansible-freeipa if you want to use the roles within the source archive.
ansible-playbook -v -i inventory/hosts install-replica.yml
This will deploy the replicas defined in the inventory file.
