Swarm: Manager in host + Worker in VM: No containers in workers

Question

I'm trying to deploy a CDN using nginx container with docker swarm. For now, i have manager in host, and one worker on VM created using docker-machine:

pierpaolo@pierpaolo-Lenovo-G580:~$ docker-machine create -d virtualbox worker1

I run manager on host:

pierpaolo@pierpaolo-Lenovo-G580:~$ docker swarm init
Swarm initialized: current node (99rr4i1w7wgn5usak9s20fikb) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join \
    --token SWMTKN-1-0tfvpvdlmugavn3fyqtjn9wkd3oeqze6nmw547shp07y73whix-4dqc404txwg58zibnz3lmp30w \
    192.168.1.101:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

Then, on worker1, i run:

docker@worker1:~$     docker swarm join \
>     --token SWMTKN-1-0tfvpvdlmugavn3fyqtjn9wkd3oeqze6nmw547shp07y73whix-4dqc40
4txwg58zibnz3lmp30w \
>     192.168.1.101:2377
This node joined a swarm as a worker.

On host, i created overlay network:

pierpaolo@pierpaolo-Lenovo-G580:~$ docker network create -d overlay mynetwork  
cb9plmvxn6twjt5lm7xgnq4ha

And created my services, with 10 replicas:

docker service create --name nginx-cdn --network mynetwork --replicas 10 -p 9999:80 nginx-new:latest
dt1rfrix71cawpr8czzy4jje4

But, as shown as following:

pierpaolo@pierpaolo-Lenovo-G580:~$ docker service ls
ID            NAME       REPLICAS  IMAGE             COMMAND
dt1rfrix71ca  nginx-cdn  0/10      nginx-new:latest  

pierpaolo@pierpaolo-Lenovo-G580:~$ docker ps

On manager (host) there are only 5 of 10 replicas, and on worker1

docker@worker1:~$ docker ps --all
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

There are no containers.

Why?

If i cmd docker service ps nginx-cdn there are some lines like these:

ID                         NAME              IMAGE             NODE                   DESIRED STATE  CURRENT STATE                 ERROR

But i created an image named "nginx-new:latest" and if i created a container from this image, it works.
