Thanks for the feedback. Actually you are right. It is an incompatibility with docker cli. However it is a client side incompatibility rather than API side.

Will fix it soon. @yyb196

@allencloud you are right, it's only on the client side.

@faycheng Could you help finish this feature? inspect related feature is implemented by you. It could not be better if you help to make inspect output an array.
