Docker swarm best practices and run image as a service


Sorry for that noob question, but i do not understand the docs an available tutorials.

I want to run docker swarm on different nodes like rpi and friends.

How to install it and setup master and slaves , I did understood.

More or less its clear for me how to run the example web services in the docker doc´s.

But i do not understand how I could run an image/container, that I got form Dockerhub in the swarm.

as example an ubuntu image from dockerhub

What is the best practice for that?

is it possible to mage it with portainer or something similar?



I guess I found it

i gthink I have to too the same for avery image
