I’m testing docker swarm on a multi node cluster.
The point is that if I create a service with docker service create and then I join nodes everything works (I user --with-registry-auth, master node is logged in to a private registry on AWS) , it means applications are replicated on nodes with image pull and containers start.
if I kill the nodes, scale the service to 0 with:
docker service scale myserv=0
and then I join a new node and try scale up, the image on the node is not pulled down, it says “no such image”,
that’s strange since if I re-create the service it is able to pull the image on nodes. It is like docker service scale doesn’t login to the remote registry in the nodes.
Any tips ?
