How to make it work

generating the server certificate and private key with OpenSSL takes just one command:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout key.pem -out
cert.pem

registry to make it work with p2p easily.

Let's run tracker on 192.168.0.1 (host1) and proxies on 192.168.0.{2,3,4} (host{2,3,4}).

host1> docker run -d --net=host bobrik/bay-tracker \
  -listen 192.168.0.1:8888 -tracker 192.168.0.4:6881 -root /tmp

Now let's run local proxies on each box:

host2> docker run -d -p 127.0.0.1:80:80 bobrik/bay-proxy \
  -tracker http://192.168.0.1:8888/ -listen :80 -root /tmp

host3> docker run -d -p 127.0.0.1:80:80 bobrik/bay-proxy \
  -tracker http://192.168.0.1:8888/ -listen :80 -root /tmp

host4> docker run -d -p 127.0.0.1:80:80 bobrik/bay-proxy \
  -tracker http://192.168.0.1:8888/ -listen :80 -root /tmp

In /etc/hosts on each machine add the next record:

127.0.0.1 p2p-<my-registry.com>

where my-registry.com should be your usual registry.

After that on host{2,3,4} you can run:

docker pull p2p-<my-registry.com>/myimage

and it will work just like

docker pull <my-registry.com>/myimage

but with p2p magic and unicorns.
