Google Cloud – Set instance hostname/FQDN

Create/edit metadata of instance at:

https://console.cloud.google.com/compute

To use the patch bellow, you need to create a metadata with key name hostname, set this to your hostname/FQDN.

Connect to instance (by SSH) and apply this patch to file /etc/dhcp/dhclient-exit-hooks.d/google_set_hostname

 # Delete entries with new_host_name or new_ip_address in /etc/hosts.
 sed -i '/Added by Google/d' /etc/hosts

To avoid lose the  patch, use this command:

# dpkg-divert --add /etc/dhcp/dhclient-exit-hooks.d/google_set_hostname

Now, reboot the instance to apply the FQDN set in metadata.

# reboot
