Docker, The Linux container engine is an open source project to pack, ship and run any application as a lightweight container.

Have look at Docker getting started.

IPv4 packet forwarding is disabled by default in PLD Linux, so internet access from inside the container will not work unless net.ipv4.ip_forward is enabled:

 WARNING: IPv4 forwarding is disabled.

To fix, run:

 sudo sysctl -w net.ipv4.ip_forward=1

Or, to enable it more permanently, enable it on the host's /etc/sysctl.conf:

  net.ipv4.ip_forward=1

Simple script to create new base image for pld:

mkimage-pld.sh

#!/bin/sh
set -e
 
ROOTFS=~/root
IMAGE=pld
 
# to clean up:
docker rmi $IMAGE
 
# build
rpm -r $ROOTFS --initdb
poldek -r $ROOTFS --up -u bash iproute2 coreutils poldek
 
# cleanups
PKGS="cracklib-dicts ca-certificates"
for pkg in $PKGS; do
    rpm -r $ROOTFS -q $pkg && rpm -r $ROOTFS -e $pkg --nodeps
done
 
# and import
tar -C $ROOTFS -cf- . | docker import - $IMAGE
 
# and test
docker run -i -u root $IMAGE /bin/echo Success.

# sh -x /vagrant/mkimage-pld.sh 
+ rpm -r /home/vagrant/root --initdb
+ poldek -r root --up -u bash iproute2
+ docker import - pld
# docker run -i -t pld bash

You can see more available samples in docker/contrib/.

also, you can try glen's pld test image:

vagrant@pld64 ~$ sudo docker run -i -t glen/pld bash
root@ae0aac5de155 ~# 

To play around inside vagrant, create Vagrantfile and run vagrant up followed by vagrant ssh.
