Configurator:

  • change_locale -> en_GB.UTF-8
  • change_timezone -> Europe/Rome
  • ssh -> Enable
  • boot_behaviour -> Boot straight to desktop? Yes

Setup bridge on host VM:

vi /etc/sysconfig/network-script/ifcfg-virbr0

DEVICE=virbr0
TYPE=Bridge
IPADDR=172.16.32.6
NETMASK=255.255.255.0

TYPE="Ethernet"
UUID="e2d7181d-be2d-496f-aa2f-d4c49832c393"
BRIDGE="virbr0"
PROMISC="yes"

Add raspberry interface to bridge:

brctl addif virbr0 vnet0
ip link set vnet0 up

Configure address on RPi interface:

sudo vi /etc/network/interfaces

iface eth0 inet static
address 172.16.32.7
netmask 255.255.255.0
gateway 172.16.32.254

sudo vi /etc/resolv.conf

nameserver 8.8.8.8

Update packages and install puppet:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install puppet

Configure server:

sudo vi /etc/puppet/puppet.conf

...
[agent]
server = puppet.derecom.it

First run:

sudo puppet agent --test --verbose

On the master:

puppet ca sign raspberrypi
