对码头工人跑码头工人撰写群

Question

我已经开始了一个码头工人师傅有：

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

所以，我尝试让我的壳点经一窝蜂主：

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

，但它给我错误：Host does not exists

任何人都知道我需要为eval $(docker-machine env --swarm <MANAGER-IP>)写点东西，所以我的写作可以在群集上运行？

林应该把主人的名字，但我不知道如何找到它

-bash-4.2$ docker node ls

你混了容器这就是被直接嵌入到泊坞CLI较新的swarmkit基于群基础群命令。有了Swarm的新版本，docker-compose并不直接支持。考虑这个测试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 CLI管理的DAB文件的支持。 DAB文件从docker-compose bundle导出，然后导入到Docker中。这个功能仍然是非常实验性的，并且有望改变。

如果没有这些，docker-compose的任何内容只能在单个docker引擎上运行，因为群集访问全部在不同的docker service CLI界面下完成。
