在不使用docker机器的情况下部署docker swarm

Question

Currently I have a bunch of RHEL7 VMs running on RackSpace and want to deploy docker swarm for testing purpose. The Docker Docs only describes the method to deploy docker swarm by using docker machine.

Question: Since VirtualBox cannot be used in VMs, are any other ways such that I can directly deploy docker swarm on my VMs without using docker machine?

Answer 1

事实上，Docker文档为您提供了如何在不使用docker-machine的情况下“手动”设置群集群集： 创建用于开发的群集

Answer 2

I think that this full step-by-step tutorial might be useful .

It details how to deploy Swarm with a multi-hosts network, without Docker-machine by using consul and suggest two different means for the Swarm agent discovery (static file and token).
