docker-compose swarm：强制容器在特定主机上运行

尝试使用Swarm独立版和docker-compose版本“2”在不同的虚拟机上运行群集应用程序.设置覆盖网络.但是想强制某些容器在特定主机上运行.

在文档中有以下建议,但使用此参数我根本无法启动任何容器：

environment:
  - "constraint:node==node-1"

ERROR: for elasticsearch1  Cannot create container for service elasticsearch1: Unable to find a node that satisfies the following conditions
[available container slots]
[node==node-1]

我们应该将主机注册为node-1 node-2 …还是默认完成.
