Setting a static IP address in a docker container using the LXC driver

I installed docker on my ubuntu 14.04 laptop. I pulled the docker registry image from the central registry. To fix the IP address of the container to a static value, I first changed mine /etc/defaults/dockerand added the variable -e lxcto DOCKER_OPTS.

Then, to run my local registry, I used the following command:

docker run \
-i -t -h myreg  \
--net="none" \
--lxc-conf="lxc.network.hwaddr=91:21:de:b0:6b:61" \
--lxc-conf="lxc.network.type = veth" \
--lxc-conf="lxc.network.ipv4 = 172.17.0.20/16" \
--lxc-conf="lxc.network.ipv4.gateway = 172.17.42.1"  \
--lxc-conf="lxc.network.link = docker0" \
--lxc-conf="lxc.network.name = eth0" \
--lxc-conf="lxc.network.flags = up" \
--name myreg \
-p 5000:5000 \
-d registry  \
/bin/bash

Then used docker attach myregto access the container shell. After installing the net-tools package, I checked its IP address and saw that it was 172.17.0.20, as expected. I tried to scan it from my master, and he answered.

The problem is that when I checked the configuration of this container with docker inspect myreg, part of the NetworkSettings output was as follows

"NetworkSettings": {
    "Bridge": "docker0",
    "Gateway": "172.17.42.1",
    "IPAddress": "172.17.0.8",
    "IPPrefixLen": 16,
    "PortMapping": null,
    "Ports": {
        "5000/tcp": [
            {
                "HostIp": "0.0.0.0",
                "HostPort": "5000"
            }
        ]
    }
