Random rpc error: code = InvalidArgument while deploying into the swarm

swarm

(Nurked) #1

I’m trying to deploy a 10-container solution into docker swarm. It works just fine on my prod and test servers, although I have problems with one of my remote clients.

The OS is Ubuntu 16.4

docker -v
Docker version 18.03.1-ce, build 9ee9f40

Specifically when I’m running the command:

docker stack deploy --compose-file=docker-compose.yaml smdr

I’m getting a very weird error message.

_smdrnetworkwork smdr
failed to create network smdrnetwork: Error response from daemon: rpc error: code = InvalidArgument desc = name must be valid as a DNS name component

I can’t find this one in google no matter how I’m trying. The name of the network is smdrnetwork and it is a valid DNS name. But as you can see on the first line the name comes out as a garble and I thing something is not being parsed just right.

I already downgraded my docker from 18.6 to 18.03, but it works just fine on my local prod server on both of those versions of docker. Ubuntu 16.4 as a server here. And this is my yaml

version: '3'
