Cant change DNS settings of LXC Debian containers

[Vasilij Lebedinskij]

Hello! I'm trying to create OMV container and connect it to AD, but I can't change DNS setting from GUI. In GUI everything is set right (domain name and server) but in LXC /etc/resofv.conf still shows localdomain and dhcp dns server. This problem persist on Debian 9 and 10 templates but if I use ubuntu 18.04 template everything works fine.

Any ideas/workarounds?

You can run

touch /etc/.pve-ignore.resolv.conf

And then edit /etc/resolv.conf manually.

touch /etc/.pve-ignore.resolv.conf

must be done inside LXC or on host?

Tried that in LXC but /etc/resolv.conf is still overwritten on reboot.

Inside the container.

Then it's not proxmox fault.

There are some services like resolvconf which overwrite it at boot from /etc/network/interfaces.

Did you set the lxc to dhcp ? It can also be overwritten from dhcp.

Grrrrrr stupid dhcp... You were right - static ip solved my issue.
