I am trying to port my "normal" container I run using:
docker run -d -p 8001:80 myImage:20181011123308
to a docker service, so I can use docker secrets. My service is running on a linux machine and should be exposed to the internet with port 8001:
docker service create --with-registry-auth --network my-overlay --name kinoheld --publish published=8001,target=80 --tty myImage:20181011123308
After a long search I found, that docker is logging the following error:
Oct 11 16:35:32 ns3311367.ip-5-135-162.eu dockerd[1621]: time="2018-10-11T16:35:32.578017228+02:00" level=error msg="fatal task error" error="starting container failed: subnet sandbox join failed for \"10.255.0.0/16\": error creating vxlan interface: operation not supported" module="node/agent/taskmanager" node.id=kafpbh873owp6e3us4zx1gghg service.id=rel9onyvcc82rrk7jsho9pgnz task.id=whnjff89hr7d6n4phvd1ead4d
But I don't know what the error means exactly and how to resolve it. Is anyone able to help me with this error and can tell me, what the problem might be?
I am currently running docker version 17.05.0-ce
My debian host is running linux:
uname -r
4.9.87-xxxx-std-ipv6-64
I was a problem with the installed linux kernel.
The VPS / root server hoster OVH does use a custom kernel, which did not have activated vxlan support.
