Tried it with the latest Docker CE Stable

Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.

Since both Edge and Stable are offering the functionality, I would recommend you upgrade to the latest stable.

@FrenchBen Well the strange fact is that it works well with 17.06.2-ce installed locally on my machine. Wondering why its not working on same version of docker in azure ..

[FrenchBen]

@nohaapav what's the git commit associated with the 17.06.2-ce on your machine? Perhaps there's a slight patch added? With this working in our current Stable and Edge release, and this not being Docker EE, I can only recommend to upgrade in order to see the functionality, or go through the debugging steps yourself.

Closing the issue, but feel free to add comments to it here, especially if you get to the root cause.

@FrenchBen git commit is completely the same within both engines (azure / local) .. Let's upgrade the engine then.
