The following config will provide you we a set of commands on how to updated a hostname on your CoreOS Linux server. Let’s start by displaying the current hostname:
localhost ~ # hostnamectl Static hostname: n/a Transient hostname: localhost Icon name: computer-desktop Chassis: desktop Machine ID: 1759d8fe862a4c17b50a56eebb7a1e26 Boot ID: 0de6b2cfbf31454299af6729737fc648 Operating System: CoreOS 723.3.0 Kernel: Linux 4.0.5 Architecture: x86-64
Using the hostnamectl
command again we now set a new hostname to coreos
:
localhost ~ # hostnamectl set-hostname coreos
Confirm a correct settings:
localhost ~ # hostnamectl Static hostname: coreos Icon name: computer-desktop Chassis: desktop Machine ID: 1759d8fe862a4c17b50a56eebb7a1e26 Boot ID: 0de6b2cfbf31454299af6729737fc648 Operating System: CoreOS 723.3.0 Kernel: Linux 4.0.5 Architecture: x86-64
Your prompt hostname will display a new hostname next time you login to your CoreOS system.
