Docker stack and private registry

Docker Engine Swarm
1

I have an error with my private registry (in dockerhub) and this command (docker 1.13):
docker stack deploy --compose-file=docker-compose.yml my_stack

Error message :
unable to pin image fidelisa/node to digest: errors:
denied: requested access to the resource is denied
unauthorized: authentication required

I am login (docker login) and docker pull fidelisa/node is working.

Any ideas ?
Thanks
Yann

try to pass --with-registry-auth option

docker stack deploy -c docker-compose.yml --with-registry-auth
(in case it still complains, delete the local cache images with docker rmi

You probably need to do docker login on each machine followed by
docker login -u username -p password registry.hub.Docker.com/myproject && Docker stack deploy -c Docker-swarm.yml test --with-registry-auth
