Docker build (MacOS vs Ubuntu)

Question

On a Mac OSX, it's possible to do this to build the docker image from a Dockerfile:

docker build -f Dockerfile .

And on a Debian/Ubuntu, the above doesn't work, it just hangs there.

docker build - < Dockerfile

But Mac OSX can take both syntax. Why is that so?

Is it because of the different Docker versions or different Dockers on different OS?

Docker on Mac:

$ docker version
Client:
 Version:      17.03.1-ce
 API version:  1.27
 Go version:   go1.7.5
 Git commit:   c6d412e
 Built:        Tue Mar 28 00:40:02 2017
 OS/Arch:      darwin/amd64

Server:
 Version:      17.04.0-ce
 API version:  1.28 (minimum version 1.12)
 Go version:   go1.7.5
 Git commit:   4845c56
 Built:        Wed Apr  5 18:45:47 2017
 OS/Arch:      linux/amd64
 Experimental: false

Docker on Ubuntu:

$ docker version
Client:
 Version:      17.06.0-ce
 API version:  1.30
 Go version:   go1.8.3
 Git commit:   02c1d87
 Built:        Fri Jun 23 21:23:31 2017
 OS/Arch:      linux/amd64

Server:
 Version:      17.06.0-ce
 API version:  1.30 (minimum version 1.12)
 Go version:   go1.8.3
 Git commit:   02c1d87
 Built:        Fri Jun 23 21:19:04 2017
 OS/Arch:      linux/amd64
 Experimental: false

If it's the different Docker version, does it mean that the docker build -f Dockerfile . is deprecated since the Mac version is older than the Ubuntu one?

Can you try to build again, but use `docker --debug build -f Dockerfile .` on the client, and run the daemon in debug mode as well? The hanging behavior certainly is not expected, so I would recommend grabbing that information and posting it so that you can get help with solving underlying problem. — programmerq, Jul 12 '17 at 12:51

As I see in my version, it is working. I'll let this answer stay here so that we know that

docker build -f Dockerfile .

works on docker version 3 on mac, docker version 5 on ubuntu, and hangs on docker version 6 on ubuntu.

Original Answer: My system runs on ubuntu and I tested both the methods to build and both worked the same way. First one being

docker build -f Dockerfile .

and second being

docker build - < Dockerfile

Maybe taking a look at my docker version would help:

$ docker version

 Version:      17.05.0-ce
