Please sign your commits following these rules:
https://github.com/moby/moby/blob/master/CONTRIBUTING.md#sign-your-work
The easiest way to do this is to amend the last commit:

$ git clone -b "master" git@github.com:Shawnpku/distribution.git somewhere
$ cd somewhere
$ git commit --amend -s --no-edit
$ git push -f

Amending updates the existing PR. You DO NOT need to open a new one.

@thaJeztah Thank you so much for the review. Already fixed.

@thaJeztah Check the changes at your convenient. Thanks.

Thanks for updating! I'm not a maintainer in this repository, so I'll leave the more in-depth review to the maintainers (I just spotted those small issues 🤗 )

oh! I see you missed a DCO sign-off on the second commit; could you

• Squash your commits (no need to keep the second commit separate, as it was only a fix-up of the first one)
• Use your real name for the sign-off (not your github handle)?

So

Signed-off-by: Shawn Chen <chen8132@gmail.com>

Instead of

Signed-off-by: Shawnpku <chen8132@gmail.com>

Please take a look @dmcgowan @caervs @manishtomar. Thanks.
