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
