FQDN as hostname for container

[floh79]

Hi I have an issue with Plesk running as container. An Plesk-extension needs the hostname is properly set as FQDN.

Let say I want name it 'server.domain.tld' (on my machine I of course use valid hostname).

I did:

hostnamectl set-hostname server.domain.tld
root@server:~# hostnamectl status | grep 'Static hostname'
   Static hostname: server.domain.tld

But after every reboot its reset to 'server' so domain is removed:

root@server:~# hostnamectl status | grep 'Static hostname'
   Static hostname: server

Why? How can I avoid that? I already changed the hostname of that container on WebGUI but it didn't help even the node is correctly displayed '110 (server.domain.tld)'

Best regards
Floh

Hello. Did you set domain.tld in the "DNS domain" field in the "DNS" section of the lxc container?

Hi, just tried that. But still didn't help, unfortunately:

root@server:~# hostnamectl status | grep 'Static hostname'
   Static hostname: server

Hi I have an issue with Plesk running as container. An Plesk-extension needs the hostname is properly set as FQDN.

the hostname is not the FQDN.

I copied an explanation from "man hostname":

The  FQDN  (Fully  Qualified Domain Name) of the system is the name that the resolver(3) returns for the host name, such as, ursula.example.com.  It is usually the hostname followed by
       the DNS domain name (the part after the first dot).  You can check the FQDN using hostname --fqdn or the domain name using dnsdomainname.

=> fix the plesk-extension?
