Question

我已经开始了一个码头大师：

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

所以，我试图让我的shell指向swarm master：

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

但它给了我一个错误：Host does not exists

任何人都知道我需要为eval $(docker-machine env --swarm <MANAGER-IP>)添加什么才能让我的作品可以在群集群上运行？

我应该把主人的名字，但我不知道如何找到它

-bash-4.2$ docker node ls

您将基于容器的swarm命令与直接嵌入Docker CLI的基于swarmkit的Swarm混合起来。使用新版本的Swarm，还没有直接支持docker-compose。考虑这是一个适用于有限范围的beta产品。您可以尝试使用docker引擎的实验版本，该版本添加了对使用docker stack CLI管理的DAB文件的支持。 DAB文件从docker-compose bundle导出，然后导入Docker。此功能仍处于试验阶段，预计会发生变化。

如果不这样，docker-compose的任何内容都只能在单个docker引擎上运行，因为swarm访问都是在不同的docker service CLI界面下完成的。

在Docker Swarm上运行Docker Compose
