Volume on Docker Swarm is not persistent?

I just want to create a service on Docker Swarm with NGINX and to make data persistent after docker-machine reboot.

I check the manager IP

docker-machine ip manager

Then I go to the machine

docker-machine ssh manager

Inside a Docker Machine I create a new service:

docker service create -p 80:80 --mount type=volume,target=/usr/share/nginx/html --name nginx nginx

Here I expect to have a service running with NGINX on the port 80 with an unnamed volume.

In a web browser I see that NGINX is online at MANAGER_IP:80.

With docker inspect CONTAINER_ID can find the path to the volume and to modify e.g. index.html.

But after docker-machine stop and docker-machine start my change disappears.

Why? What do I have to do to make it persistent (to be available after rebooting docker-machine) ?

Any advice much appreciated.

can you try this

docker service create -p 80:80 --mount type=volume,source=myvolume,destination=/usr/share/nginx/html --name nginx nginx

You just didn't mention the source in your command
