Changing the hostname
BeetleboxCI runs on the Kubernetes platform, and the hostname of a machine can only contain lowercase alphanumeric characters and hyphens. Kubernetes is unable to correct address machines whose hostname does not meet these requirements.
The command to change the hostname in Linux is:
$ hostnamectl set-hostname newname
You can verify that the change has taken effect by running one of the following commands:
$ hostname
$ cat /etc/hostname
