I am using Gentoo as Host OS for Docker containers. I have compiled
kernel using instructions on page
https://wiki.gentoo.org/wiki/Docker#Kernel and I have installed Docker
from Gentoo repository.

Host system informations:

    pecan@tux ~ $ uname -a
    Linux tux 4.12.12-gentoo #8 SMP Sat Oct 7 13:58:47 CEST 2017 x86_64
Intel(R) Core(TM) i5-6300HQ CPU @ 2.30GHz GenuineIntel GNU/Linux

Docker version:

    pecan@tux ~ $ docker version
    Client:
     Version:      17.03.2-ce
     API version:  1.27
     Go version:   go1.9.1
     Git commit:   f5ec1e2
     Built:        Sat Oct  7 14:50:59 2017

    Cannot connect to the Docker daemon at unix:///var/run/docker.sock.
Is the docker daemon running?

Look at "Cannot connect to the Docker daemon at
unix:///var/run/docker.sock. Is the docker daemon running?". The same
message appears if I try get docker system-wide informations:

    pecan@tux ~ $ docker info
    Cannot connect to the Docker daemon at unix:///var/run/docker.sock.
Is the docker daemon running?

The same error appears if I try run the same command as sudo, so this
error applies to daemon. I tried to check if there a mistake in Docker
daemon privileges.

    pecan@tux ~ $ sudo docker info
    Cannot connect to the Docker daemon at unix:///var/run/docker.sock.
Is the docker daemon running?

Based on the message I am able to say that maybe Docker daemon not
running. I checked daemon status to make sure:

    pecan@tux ~ $ sudo service docker status
     * status: crashed

Docker daemon is crashed. To see the reason, I looked at the logs:

    pecan@tux ~ $ cat /var/log/docker.log
    time="2017-10-07T14:52:13.178261811+02:00" level=info

    Error starting daemon: Error initializing network controller: list
bridge addresses failed: no available network

Currently, that is a point in that I do not know what should I do to be
able run Docker daemon.

Useful informations:

- I am connected to OpenVPN through UDP.
- I have disabled iptables and ip6tables.
- I have set 8.8.8.8 and 8.8.4.4 DNS providers.
- I have running privoxy and tor daemons.
- I use OpenRC init system.

Can you help me?
