docker - 在Docker Swarm上运行Docker Compose

Question

我已经开始了一个docker master:

docker swarm init --advertise-addr <MANAGER-IP>

所以，即时通讯试图通过以下方式指向我的shell群体:

eval $(docker-machine env --swarm <MANAGER-IP>)

但这给了我一个错误:Host does not existsdocker info:

有人知道我需要为eval $(docker-machine env --swarm <MANAGER-IP>)输入什么内容，以便我的撰写可以在群集集群上运行吗？

我应该输入主人的名字，但我不知道如何找到它

-bash-4.2$ docker node ls

您正在将基于容器的swarm命令与直接嵌入到Docker CLI中的更新的基于swarmkit的Swarm混合在一起。在新版本的Swarm中，尚不直接支持docker-compose。将此产品视为适用于有限范围的Beta版产品。您可以尝试实验性的docker引擎发行版，该发行版增加了对使用docker stack CLI管理的DAB文件的支持。从docker-compose bundle导出DAB文件，然后将其导入Docker。此功能仍处于试验阶段，有望改变。

否则，任何带有docker-compose的内容都只能在单个docker引擎上运行，因为全部访问都是在不同的docker service CLI界面下完成的。
