Setup PoS private network

Hi.
We need to setup PoS private network with Caspeк protocol.

There are only couple links which uses this git repo: https://github.com/karlfloersch/docker-pyeth-dev
which contains already configured docker files with necessary files.
We have checked this variant and seems there are some issues with pyethapp client.
Probably because of pretty outdated sources from which it was built.
Is there some new versions or how to build it from scratch?

Please advice.

that’s a little bit outdated, and we are working on a new one. Meanwhile you can try playing with the harmony containers https://github.com/mkalinin/harmony-docker/tree/master/casper
