ipaserver role

Description

This role allows to configure and IPA server.

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.

Features

• Server deployment

Supported FreeIPA Versions

FreeIPA versions 4.5 and up are supported by the server role.

Supported Distributions

• RHEL/CentOS 7.6+
• Fedora 26+
• Ubuntu

Requirements

Controller

• Ansible version: 2.8+

Node

• Supported FreeIPA version (see above)
• Supported distribution (needed for package installation only, see above)

Limitations

External CA

External CA support is not supported or working. The currently needed two step process is an issue for the processing in the role. The configuration of the server is partly done already and needs to be continued after the CSR has been handled. This is for example breaking the deployment of a server with replicas or clients in one playbook.

Work is planned to have a new method to handle CSR for external CAs in a separate step before starting the server installation.

Usage

Example inventory file with fixed domain and realm, setting up of the DNS server and using forwarders from /etc/resolv.conf:

[ipaserver]
ipaserver2.example.com

[ipaserver:vars]
ipaserver_domain=example.com
ipaserver_realm=EXAMPLE.COM
ipaserver_setup_dns=yes
ipaserver_auto_forwarders=yes

Example playbook to setup the IPA server using admin and dirman passwords from an Ansible Vault file:

- name: Playbook to configure IPA server
  hosts: ipaserver
  become: true
  vars_files:
  - playbook_sensitive_data.yml

  roles:
  - role: ipaserver
    state: present

Example playbook to unconfigure the IPA client(s) using principal and password from inventory file:

- name: Playbook to unconfigure IPA server
  hosts: ipaserver
  become: true

  roles:
  - role: ipaserver
    state: absent

Example inventory file with fixed domain, realm, admin and dirman passwords:

[ipaserver]
ipaserver.example.com

[ipaserver:vars]
ipaserver_domain=example.com
ipaserver_realm=EXAMPLE.COM
ipaadmin_password=MySecretPassword123
ipadm_password=MySecretPassword234

Example playbook to setup the IPA server using admin and dirman passwords from inventory file:

- name: Playbook to configure IPA server
  hosts: ipaserver
  become: true

  roles:
  - role: ipaserver
    state: present

Playbooks

The playbooks needed to deploy or undeploy a server are part of the repository in the playbooks folder. There are also playbooks to deploy and undeploy clusters.

install-server.yml
uninstall-server.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.

How to setup a server

ansible-playbook -v -i inventory/hosts install-server.yml

This will deploy the server defined in the inventory file.
