Hi Jake,
when trying Docker Containers inside Virtuozzo 7 Containers, please make sure
you have
kernel 3.10.0-327.18.2.vz7.14.7 or later.
And if there are any issues with Docker application template, please let us
know,
but in fact it's enough to:
* load "veth", "overlay" kernel modules on the host
* enable full netfilters for the VZ 7 CT (to be run on a stopped Container):
# prlctl set $CTID --netfilter=full
And after that install and use Docker inside a VZ7 CT like it's done on any
full OS without Docker application template installation.

Konstantin Khorenko,

You can try to create container from centos-7-x86_64 template and then
install docker app template there:
# vzctl create 111 --ostemplate centos-7-x86_64
# vzctl start 111
# vzpkg install 111 docker
It can require some preparations though; pre-install script checks them and
refuses to proceed if anything is wrong. Currently it checks that
"bridge:on" feature is set and netfilter is set to "full"
(https://src.openvz.org/projects/OVZT/repos/centos-7-x86_64-ez/browse/docker_pre-install-hn#42).

Greetings,
Just a quick question - I've been reading that it's possible to spin
up docker apps inside OVZ 7 containers - are there any particular
preparations or workarounds required, in the way of differences from a
docker install on a full OS?
Disclaimer - I haven't done anything with docker, but I'm curious to
see how useful it might be, and in particular, how well it works
inside a Linux container.
Jake
