moby issue 9132 seems to indicate that you can push in parallel:

this was included in the 1.10.3 release, but requires a registry 2.3.x.

You would need to:

• thread your docker push
• change the --max-concurrent-uploads int of the docker daemon to 100 at least, in order to maximize the number of parallel pushed (by default limited to 5)
• make sure your network upload capacity can handle that kind of parallel queries!

Beside that, parallel push is requested since 2014 (see issue 7336 )
There is PR 458 , but...

This change doesn't not address the fundamental problems that are brought up when requesting this feature.
The idea behind multiple push/pull arguments is that they are parallelized, but this simply performs them in sequence. This design provides no advantage over for i in images; do docker push $i; done for i in images; do docker push $i; done for i in images; do docker push $i; done .

So you still need to script the threading of docker push .
