I'm trying to use Nethserver 7.4 in several containers for services like proxy, chat, VoIP, Mail, etc.
Installing Nethserver in a KVM is pretty straightforward, but doing the same in a CT has some caveats. This is how I did it:

Create CT ssh-public-keys must be a file with a ssh-rsa ..... user@host format:
Code:
pct create 101 inf-jfernandez-nfs:vztmpl/centos-7-default_20171212_amd64.tar.xz --rootfs local-zfs:20 --ostype centos --cores 4 --memory 1024 --swap 1024 --net0 name=eth0,bridge=vmbr0,gw=192.168.###.###,ip=192.168.###.###/##,type=veth --net1 name=eth1,bridge=vmbr1,gw=###.###.###.###,ip=###.###.###.###/##,type=veth --hostname 'nethserver' --searchdomain 'domain.lan' --nameserver '192.168.###.###' --ssh-public-keys ~/opt/ssh_rsa_keys.txt

Start and enter CT:
Code:
pct start 101
pct enter 101

Set root password:
Code:
passwd

Update system and install man pages, nano, ssh, command autocompletion, needs-restarting, iptables save config, dig nslookup and other dns tools:
Code:
yum update
yum install man-pages man nano openssh-server openssh-clients bash-completion yum-utils deltarpm iptables-services bind-utils

Enable NethServer 7 software repositories and install nethserver base system:
Code:
yum localinstall -y http://mirror.nethserver.org/nethserver/nethserver-release-7.rpm
nethserver-install

After install Network Devices are not detected by nethserver so they must be declared manually:
Code:
db networks set eth1 ethernet role red ipaddr ###.###.###.### netmask 255.255.255.### bootproto none gateway ###.###.###.###
db networks set eth0 ethernet role green ipaddr 192.168.###.### netmask 255.255.255.### bootproto none gateway 192.168.###.###
db networks set red1 provider interface eth1 weight 1
signal-event interface-update

Problem with this setup is that you won't be able to edit the Network Devices on the web interface. Nevertheless you can change this parameters over and over.
