Setting up multiple machines to be in selenium grid using Docker compose

Question

I am having trouble creating a selenium grid using 2 machines.

I am trying to use docker compose, and host the hub on one machine with the 2 machine just connecting nodes and ultimately some load balancing.

seleniumhub:
 image: selenium/hub
 ports:
  - 4444:4444

chrome:
image: selenium/node-chrome
links:
 - seleniumhub:hub

above is my yml file and this runs fine and I am able to scale it easily with the following command

docker-compose up -d --scale chrome=5

but my question is if I had the 2nd machine how would I spin a node up on that machine and hook/link it to the hub on the 1st machine.

I have seen forums using links, networks, and environments but nothing is working from my end.

Does anyone know of a decent guide to get this going?

我会说要使用docker-swarm，所以您的第二台计算机将成为第一台计算机的 群集工作程序节点， 这是一个示例，也是这个示例
