How to add ip alias to network interface in lzc proxmox?

Question

Proxmox

Actually, I would like to have several IPs on the server so that I can access external services more actively.
In openvs, this was done with a pinch.
It is impossible to raise lxc eth0:1 from inside, it is also impossible to hang an alias from the web interface.
How to be?

Answer 1

can be done via ip addr add
