docker id には大文字が使えないっぽい。

Capital letter case (Error)

$ docker login

Username: YumaInaura
Password:

Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password

Lower letter case (Succeed)

$ docker login

Username: yumainaura
Password:

Login Succeeded

If you inputted capital case to Username,

This interface replace capital case with lower case silently.

Opps!

Replace letter case automatically in docker services is better.

And I think "Username" expression is bad
Display "username" is better.
