docker,package name should not support upper case?

[He-Pin]

if I use gateServer then,it comes

repository name component must match "[a-z0-9](?:-*[a-z0-9])*(?:[._][a-z0-9](?:-*[a-z0-9])*)*"

but gateserver works.

packageName in Docker := "gateServer"

Have a look at the regular expression mentioned in the error:

repository name component must match "[a-z] ...

It's [a-z]. which means lowercase only. Uppercase is NOT supported,

AFAIK docker still doesn't support uppercase letters. So we validate your package name upfront for you.
