Ansible Role : set_hostname

This role set the servers hostname based on the MAC address of the primary network interface.

Requirements

None.

Role Variables

vars/main.yml

Requires the MAC address of the primary network interface and the desired hostname to be entered.

  mac_address_mapping:
  "00:50:56:e4:3b:74":
    name: centos7.test
  "00:50:56:13:3f:c6":
    name: centos8.test
  "00:50:56:55:f5:d8":
    name: debian10.test

This means that a server with the primary network interface mac address set to 00:50:56:e4:3b:74 would get its hostname set to centos7.test.

NOTE

It is worth noting that a couple of things are set differently depending on the OS family. This includes the /etc/hostname file and the servers hostname.

For example:

• On a RedHat based systems the hostname would be set to servername.domainname.
• On a Debian based systems the hostname would be set to servername.

Dependencies

None.
