Host module
===========
Description
-----------
The host module allows to ensure presence, absence and disablement of hosts.
The host module is as compatible as possible to the Ansible upstream `ipa_host` module, but additionally offers to disable hosts.
Features
--------
* Host management
Supported FreeIPA Versions
--------------------------
FreeIPA versions 4.4.0 and up are supported by the ipahost module.
Requirements
------------
**Controller**
* Ansible version: 2.8+
**Node**
* Supported FreeIPA version (see above)
Usage
=====
Example inventory file
```ini
[ipaserver]
ipaserver.test.local
```
Example playbook to ensure host presence:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is present
- ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
description: Example host
ip_address: 192.168.0.123
locality: Lab
ns_host_location: Lab
ns_os_version: CentOS 7
ns_hardware_platform: Lenovo T61
mac_address:
- "08:00:27:E3:B1:2D"
- "52:54:00:BD:97:1E"
state: present
```
Compared to `ipa host-add` command no IP address conflict check is done as the ipahost module supports to have several IPv4 and IPv6 addresses for a host.
Example playbook to ensure host presence with several IP addresses:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is present
- ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
description: Example host
ip_address:
- 192.168.0.123
- 192.168.0.124
- fe80::20c:29ff:fe02:a1b3
- fe80::20c:29ff:fe02:a1b4
locality: Lab
ns_host_location: Lab
ns_os_version: CentOS 7
ns_hardware_platform: Lenovo T61
mac_address:
- "08:00:27:E3:B1:2D"
- "52:54:00:BD:97:1E"
state: present
```
Example playbook to ensure IP addresses are present for a host:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is present
- ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
ip_address:
- 192.168.0.124
- fe80::20c:29ff:fe02:a1b4
action: member
state: present
```
Example playbook to ensure IP addresses are absent for a host:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is present
- ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
ip_address:
- 192.168.0.124
- fe80::20c:29ff:fe02:a1b4
action: member
state: absent
```
Example playbook to ensure host presence without DNS:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is present without DNS
- ipahost:
ipaadmin_password: MyPassword123
name: host02.example.com
description: Example host
force: yes
```
Example playbook to ensure host presence with a random password:
```yaml
---
- name: Ensure host with random password
hosts: ipaserver
become: true
tasks:
- name: Host host01.example.com present with random password
ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
random: yes
force: yes
register: ipahost
- name: Print generated random password
debug:
var: ipahost.host.randompassword
```
Please remember that the `force` tag will also force the generation of a new random password even if the host already exists and if `update_password` is limited to `on_create`.
Example playbook to ensure presence of several hosts with a random password:
```yaml
---
- name: Ensure hosts with random password
hosts: ipaserver
become: true
tasks:
- name: Hosts host01.example.com and host01.example.com present with random passwords
ipahost:
ipaadmin_password: MyPassword123
hosts:
- name: host01.example.com
random: yes
force: yes
- name: host02.example.com
random: yes
force: yes
register: ipahost
- name: Print generated random password for host01.example.com
debug:
var: ipahost.host["host01.example.com"].randompassword
- name: Print generated random password for host02.example.com
debug:
var: ipahost.host["host02.example.com"].randompassword
```
Please remember that the `force` tag will also force the generation of a new random password even if the host alreay exists and if `update_password` is limited to `on_create`.
Example playbook to ensure presence of host member principal:
```yaml
---
- name: Host present with principal
hosts: ipaserver
become: true
tasks:
- name: Host host01.example.com present with principals host/testhost01.example.com and host/myhost01.example.com
ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
principal:
- host/testhost01.example.com
- host/myhost01.example.com
action: member
```
Example playbook to ensure presence of host member certificate:
```yaml
- name: Host present with certificate
hosts: ipaserver
become: true
tasks:
- name: Host host01.example.com present with certificate
ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
certificate:
- MIIC/zCCAeegAwIBAg...
action: member
```
Example playbook to ensure presence of member managedby_host for serveral hosts:
```yaml
---
- name: Host present with managedby_host
hosts: ipaserver
become: true
tasks:
ipahost:
ipaadmin_password: MyPassword123
hosts:
- name: host01.exmaple.com
managedby_host: server.exmaple.com
- name: host02.exmaple.com
managedby_host: server.exmaple.com
action: member
```
Example playbook to disable a host:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is disabled
- ipahost:
ipaadmin_password: MyPassword123
name: host01.example.com
update_dns: yes
state: disabled
```
`update_dns` controls if the DNS entries will be updated in this case. For `state` present it is controlling the update of the DNS SSHFP records, but not the the other DNS records.
Example playbook to ensure a host is absent:
```yaml
---
- name: Playbook to handle hosts
hosts: ipaserver
become: true
tasks:
# Ensure host is absent
- ipahost:
ipaadmin_password: password1
name: host01.example.com
state: absent
```
