Setting up my first swarm I’m trying to create a service. I found I needed a private repository so I used docs.docker.com/registry/ to do that. I pushed my image to it and I can run it successfully using ‘docker run’. When I attempt to create a service it fails with
"Not continuing with pull after error: Error while pulling image: Get http ://localhost:5000/v1/repositories/workflow-headless/images: dial tcp 127.0.0.1:5000: getsockopt: connection refused"
I did login to docker before running the service create command. I also experimented with adding an insecure-registries entry into /etc/docker/daemon.json as described in github.com/docker/distribution/issues/1874 which didn’t make any difference.
I missed a step somewhere. My repo can serve a ‘docker run’ but not a ‘service create’.
Anyone know what I missed?

Here’s my full service create command:
docker service create --with-registry-auth --name=workflow-headless --network madura-network --mount type=bind,src=/home/roger/madura-workflows/madura-workflows/madura-workflow-impl/bundles,dst=/bundles -e workflow.bundles.dir=/bundles,readonly localhost:5000/workflow-headless:latest
The docker run command (which works) is:
docker run -v /home/roger/madura-workflows/madura-workflows/madura-workflow-impl/bundles:/bundles --env-file ./env.list -it --rm localhost:5000/workflow-headless:latest
(yes, I’m giving it more env variables than the service create, but that shouldn’t be relevant to this problem)
I changed the http and https to add a space to get past the ‘only two links’ restriction
Thanks for any help
