我已经按照本指南在 Docker for Mac 中设置了一个 swarm 集群： https ://medium.com/@alexeiled/docker-swarm-cluster-with-docker-in-docker-on-macos-bdbb97d6bb07#.2x5gqgrkq

一切似乎都正常工作，我能够看到集群。

$ docker node ls
ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
3ez478atbfrcwb66u892ccbpx    worker-2  Ready   Active
7qfb87e9n54q3at9enzgeeko1    worker-3  Ready   Active
cnr8tyaf1qqgkpjqnn4wmnb1e *  moby      Ready   Active        Leader
eyksqiw6ewfks7t8fr48rppia    worker-1  Ready   Active

现在我想在 swarm 中创建一个 docker 注册表。

以下失败：

$ docker service create --name registry -p 5000:5000 \
--mount "type=bind,source=$PWD,target=/var/lib/registry" \
--reserve-memory 100m registry

和

$ docker service ps registry
ID                         NAME            IMAGE     NODE      DESIRED STATE  CURRENT STATE                    ERROR
2xflgt6jlqlbpgdjvfzbgbsbb  registry.1      registry  worker-1  Ready          Rejected less than a second ago  "invalid bind mount source, so…"
4u3a5bsdjavwubsgw9f0qhusx   \_ registry.1  registry  worker-3  Shutdown       Rejected 5 seconds ago           "invalid bind mount source, so…"
bqtbchxwjry7repyb7q30yes7   \_ registry.1  registry  worker-1  Shutdown       Rejected 10 seconds ago          "invalid bind mount source, so…"
3e32pquyatzdnu8jvc88tfaih   \_ registry.1  registry  worker-3  Shutdown       Rejected 15 seconds ago          "invalid bind mount source, so…"
563lpzhz10ugu6tbckdzx41xe   \_ registry.1  registry  worker-1  Shutdown       Rejected 20 seconds ago          "invalid bind mount source, so…"

检查容器给了我：

...
...
...
            "ContainerSpec": {
            "Image": "registry",
            "Mounts": [
                {
                    "Type": "bind",
                    "Source": "/Users/user1/cd-summit/docker",
                    "Target": "/var/lib/registry"
                }
            ]
        },
...
...
...
        "Status": {
        "Timestamp": "2016-11-17T12:36:06.714513328Z",
        "State": "rejected",
        "Message": "resolving controller failed",
        "Err": "invalid bind mount source, source path not found: /Users/user1/cd-summit/docker",
        "ContainerStatus": {}
    },
...
...
...

我发现http://lucjuggery.com/blog/?p=753让我可以进入 Mac 上的 moby VM。可以在 moby 中看到挂载，并且上面的命令可以正常工作，而注册表正在运行：

$ docker service ps registry
ID                         NAME        IMAGE     NODE  DESIRED STATE  CURRENT STATE           ERROR
7iw0jig2ysi5t7ha6422mulwc  registry.1  registry  moby  Running        Running 33 minutes ago

当所有其他命令似乎都工作时，为什么它不能从本机 docker 客户端工作？
