Getting "no such network" errors starting a stack in a swarm

General Discussions

I’m trying to build a test lab on my local Ubuntu 17.10 machine using VirtualBox docker hosts.

I set up a bunch of hosts using docker-machine:

docker-machine create --driver virtualbox swarm01
docker-machine create --driver virtualbox swarm02
docker-machine create --driver virtualbox swarm03
docker-machine create --driver virtualbox swarm04
docker-machine create --driver virtualbox swarm05

And then created a stack

eval $(docker-machine env swarm01)
docker swarm init --advertise-addr $(docker-machine ip swarm01)
eval $(docker-machine env swarm02) && $(docker swarm join-token manager | grep docker)
eval $(docker-machine env swarm03) && $(docker swarm join-token manager | grep docker)
eval $(docker-machine env swarm04) && $(docker swarm join-token worker | grep docker)
eval $(docker-machine env swarm05) && $(docker swarm join-token worker | grep docker)

That all seems to work without errors, and docker node ls shows the swarm:

ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS
er97lp8ro5wpr5qha8yh8td4f *   swarm01             Ready               Active              Leader
4catt6lqw2bi2vvngqlt4bs4e     swarm02             Ready               Active              Reachable
t7prg842c6xae6xrjim0drpng     swarm03             Ready               Active              Reachable
bm13dlgfa4f78ip80xxbsquy4     swarm04             Ready               Active              
xyro04ihidkji9v2k0uk53glx     swarm05             Ready               Active

I then try to deploy a simple container (here I’m using ubuntu, but I tried with various others with the same effect):

docker stack deploy -c docker-compose.yml test

This tries to start the container on each node, but it fails on all of them with an error of:

"starting container failed: No such network: test_default"

Looking in docker network ls seems to show that network does exist:

NETWORK ID          NAME                DRIVER              SCOPE
922b803e55a7        bridge              bridge              local
60ee96eb1d34        docker_gwbridge     bridge              local
64b4abf7d243        host                host                local
qnkqzhpg8cko        ingress             overlay             swarm
cc70ba8a51c8        none                null                local
r468xyv7rb5l        test_default        overlay             swarm

This is using Docker version 17.10.0-ce, build f4ffd25

I am encountering the same issue. Service does not start due to network missing, though it is listed.

Any progress?

Got my case fixed as it turned out to be related to the defined container having issues on its own preventing it from starting properly. After fixing several aspects with testing the container as such prior to embedding it into some stack I got it running eventually in the very same swarm I was using before. So, AFAIC this error message seems to be misleading.

I’m having a similar issue with a Docker Stack. I rebooted the server and one of my services doesn’t start and the error in the service status is “no such network” as described above.

I can run docker service scale service_name=0 wait a few seconds and then scale it back to 1 and the service starts up fine. This is an easy fix, but kind of terrible to have to go through this.

Any ideas?

same issue

I think we need wait for the next release

Good find @llitfkitfk, thank you! I verified that 17.11 does, indeed, fix the issue. I added the following to /etc/apt/sources.list.d/docker.list:

deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial edge

Per the edge instructions, I stopped all my containers by scaling my services down to 0 prior to installation, then apt-get update and apt-get upgrade, and scaled services back up. Once everything was running again, I rebooted to ensure all my services started as expected.
