## Overview
|
||
|
||
Manage some basics configuration for IPR's servers.
|
||
|
||
## Role Variables
|
||
|
||
* **basics__domain** : Domain to use [default : `{{ ansible_domain }}`].
|
||
* **basics__hosts_localhost_manage** : If the localhost (127.0.0.1) line should be managed [default : `false`].
|
||
* **basics__hosts_localhost_content** : Content of the localhost (127.0.0.1) line [default : `localhost.localdomain localhost`].
|
||
* **basics__hosts_ipv4_manage** : If the ipv4 address line should be managed [default : `false`].
|
||
* **basics__hosts_ipv4_content** : Content of the ipv4 address line [default : `{{ ansible_hostname }}.{{ basics__domain }} {{ ansible_hostname }}`].
|
||
* **basics__proxmox_disable_hosts** : Disable the management of **/etc/hosts** file by Proxmox for LXC containers [default : `True`].
|
||
|
||
## Example Playbook
|
||
|
||
* If you want to manage both localhost (127.0.0.1) and permanent IP (ipv4) lines :
|
||
|
||
``` yml
|
||
- hosts: serverXYZ
|
||
roles:
|
||
- role: ipr-cnrs.basics
|
||
basics__hosts_localhost_manage: true
|
||
basics__hosts_ipv4_manage: true
|
||
```
|
||
|
||
* If the domain is not defined on the remote host, you should set the `basics__domain` variable :
|
||
|
||
``` yml
|
||
- hosts: serverXYZ
|
||
roles:
|
||
- role: ipr-cnrs.basics
|
||
basics__domain: 'mydomain.org'
|
||
basics__hosts_ipv4_manage: true
|
||
````
|
||
|
||
## Configuration
|
||
|
||
### Hosts
|
||
|
||
Ensure to have the correct fqdn and hostname in /etc/hosts :
|
||
- You can define the domain if it's not correct on the remote host.
|
||
- You can choose to define the localhost (127.0.0.1) line content.
|
||
- You can choose to define the permanent ip (ipv4) line content.
|
||
- All other lines that contains hostname without this permanent ip address will be removed.
|
||
|
||
For LXC containers, also ensure to disable the management of /etc/hosts by Proxmox :
|
||
- Touch a /etc/.pve-ignore.hosts file.
|
||
|
||
## Development
|
||
|
||
This source code comes from our [Gogs instance][basics source] and the [Github repo][basics github] exist just to be able to send the role to Ansible Galaxy…
|
||
|
||
But feel free to send issue/PR here :)
|
||
|
||
Thanks to this [hook][gogs to github hook], Github automatically got updates from our [Gogs instance][basics source] :)
