在Docker Swarm上运行Docker Compose

我已经开始了一个docker大师：

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

所以，即时通讯尝试让我的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

docker info ：

 -bash-4.2$ docker info Containers: 18 Running: 1 Paused: 0 Stopped: 17 Images: 20 Server Version: 1.12.0 Storage Driver: devicemapper Pool Name: docker-253:1-25646-pool Pool Blocksize: 65.54 kB Base Device Size: 10.74 GB Backing Filesystem: xfs Data file: /dev/loop0 Metadata file: /dev/loop1 Data Space Used: 3.124 GB Data Space Total: 107.4 GB Data Space Available: 13.4 GB Metadata Space Used: 5.071 MB Metadata Space Total: 2.147 GB Metadata Space Available: 2.142 GB Thin Pool Minimum Free Space: 10.74 GB Udev Sync Supported: true Deferred Removal Enabled: false Deferred Deletion Enabled: false Deferred Deleted Device Count: 0 Data loop file: /var/lib/docker/devicemapper/devicemapper/data WARNING: Usage of loopback devices is strongly discouraged for production use.

任何人都知道我需要放在eval $(docker-machine env --swarm <MANAGER-IP>)所以我的作品可以在swarm集群上运行？

我应该把主名称，但我不知道如何find它

 -bash-4.2$ docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 05szzy2z96ypgl5k21swggoil * scsor0004331002.rtp.openenglab.netapp.com Ready Active Leader 59t110b0wjhitj1fr8erys600 scsor0004331003.rtp.openenglab.netapp.com Ready Active dhm6utu2w3dw1to0zh3n71moq scsor0004331004.rtp.openenglab.netapp.com Ready Active

您将基于容器的群集命令与直接embedded到Docker CLI中的基于Swarmkit的新Swarm混合起来。 在Swarm的新版本中，docker-compose并不直接支持。 考虑这个testing版产品，在有限的范围内运行良好。 您可以尝试Docker引擎的实验版本，该引擎添加了对由docker stack CLIpipe理的DAB文件的支持。 DAB文件从docker-compose bundle中导出，然后导入到Docker中。 这个function还是非常实验性的，预计会有所改变。

没有这些， docker-compose任何东西都只能在一个docker引擎上运行，因为swarm的访问全部在不同的docker service CLI接口下完成。
