"docker: 'manifest' is not a docker command.'

[Drillan767]

Description

I can't create a manifest file from the docker command line

Steps to reproduce the issue:

1. simply type "docker manifest" from the console

Describe the results you received:
When typing "docker manifest create" or just "docker manifest", I only get one result:
"docker: 'manifest' is not a docker command.'
Also, when typing "docker --help", 'manifest' doesn't show up

Additional environment details (AWS, VirtualBox, physical, etc.):

Well I don't know, I use Docker Hub, and my initial goal was to create an image so that it could be both compatible to AMD64 and ARM, but I'm new to Docker so I'm pretty much lost
