Error when starting docker.service

Docker Engine Swarm
, ,
1

Hello,
so my problem is that when I try to connect a node (Raspberry Pi zero W w/ Raspbian Stretch) to a swarm manager, it says:

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

So, when I try and run the service, this happens:

sudo systemctl restart docker

Job for docker.service failed because a fatal signal was delivered causing the control process to dump core.
See "systemctl status docker.service" and "journalctl -xe" for details.

This is the output of “systemctl status docker.service”:

docker.service - Docker Application Container Engine

And this the output of “journalctl -xe”:

I hope you can help me solve this problem, because I have no idea of what to do.
By the way, the manager node is running on a Rapberry Pi 3B w/ Debian Stretch too, and that one is working at least for now.

Thank you! :smile:

Hi

How did you install it?
My guess is that you installed the x86_64 version, and not armhf version.

I installed Docker on all 4 systems using the same method: the convenience script.
I say 4 systems because I’m using 3 Rapberry Pi Zero W and a 3B, and Docker works on the 3B, but not on the 'Zero W’s, and they were all installed in the same way :man_shrugging:

4

I have this issue with Pi Zero W too.

5

same for me brand new pi Zero W, latest raspbian , nothing installed .
Docker install shows no error
does not start and i get
segmentation fault

6

I am having the same problem.
Any answers yet?

That is a known issue if you installed Docker 18.09.1.
The workaround is to install 18.06.03 till a patch release becomes available for 18.09.
