 Posted: Sat Oct 07, 2017 3:34 pm Post subject: Error while starting Docker daemon |
 |
|
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:
| Code: | 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:
| Code: | 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
OS/Arch: linux/amd64
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:
| Code: | 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.
| Code: | 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:
| Code: | pecan@tux ~ $ sudo service docker status
* status: crashed |
Docker daemon is crashed. To see the reason, I looked at the logs:
| Code: | pecan@tux ~ $ cat /var/log/docker.log

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? |

Your emerge result (probably) mentioned something about needed kernel settings, run the following to see missing options:
| Code: |
exec /usr/share/docker/contrib/check-config.sh
