This is how to set up a new build server.

# Create the container
lxc-create -n build-3-1-x86 -t alpine -- --arch x86 --release edge

# Make it autostart
ln -s lxc /etc/init.d/lxc.build-3-1-x86 && rc-update add lxc.build-3-1-x86

# setup ip forward for ssh
iptables -t nat -A PREROUTING -d 91.220.88.21/32 -p tcp -m tcp --dport 22031 -j DNAT --to-destination 192.168.8.31:22
/etc/init.d/iptables save
lbu commit

# Create missing dir
mkdir /var/lib/lxc/build-3-1-x86/rootfs/var/cache/distfiles

# copy authorized_keys:
cp -a /var/lib/lxc/build-3-0-x86/rootfs/root/.ssh /var/lib/lxc/build-3-1-x86/rootfs/root/

# set up network:
vi /var/lib/lxc/build-3-1-x86/rootfs/etc/network/interfaces

Contents of /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
	address 192.168.8.31
	netmask 255.255.255.0
	gateway 192.168.8.1

# Start container
/etc/init.d/lxc.build-3-1-x86 start

# log in as root
lxc-console -n build-3-1-x86

# make netowrking autostart
rc-update add networking

# install and set up ssh
apk add openssh
rc-update add sshd
/etc/init.d/sshd start
mkdir /root/.ssh
cat > /root/.ssh/authorized_keys
# paste the ssh keys and ctrl-d

# logout
exit

#and detach from console: ctrl-a q

Log in via ssh.

# install alpine-sdk, sudo and aports-build
apk add alpine-sdk sudo aports-build

# make users in %wheel group rin commands without passwd
visudo

# create buildozer user (with good passwd)
adduser buildozer
addgroup buildozer abuild

From host, copy over buildozer keys from other build server:

cp -a /var/lib/lxc/build-3-0-x86/rootfs/home/buildozer/.abuild /var/lib/lxc/build-3-1-x86/rootfs/home/buildozer/ cp -a /var/lib/lxc/build-3-0-x86/rootfs/home/buildozer/.ssh /var/lib/lxc/build-3-1-x86/rootfs/home/buildozer/

You should now be able to log in via ssh as buildozer.
