How do managers and workers interact in docker swarm?

Question

Docker

Good evening.
Please don't talk about Google. You can not or too lazy to answer - do not answer.

I recently started learning Docker. Learned about docker swarm. I saw an example with an nginx image that displays the container ID, which, accordingly, is constantly changing.

It became interesting to me how exactly (can I have a code example?), How manager interacts with workers in docker sworm. How does it determine to whom, whom and what data to transfer and how it transfers?

Answer 1

This all happens automatically, it starts a network that works through their own data protocol, and passes traffic to where the working worker is. Therefore, you can contact any worker, and the traffic will go where it decides.
