在使用Docker for Mac的群集服务中挂载“pwd”

我已经按照这个指南在Docker for Mac中build立了一个群集： https : //medium.com/@alexeiled/docker-swarm-cluster-with-docker-in-docker-on-macos-bdbb97d6bb07#.2x5gqgrkq

所有似乎正常工作，我能够看到群集。

$ 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build一个dockerregistry。

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 

同

 $ 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 ，这让我能够进入Mac上的moby虚拟机。 moby里面可以看到坐骑，上面的命令没有问题，运行registry：

 $ 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起作用时，为什么它不能从本地docker客户端运行？
