Does Packer v1.1.0 didn't support docker engine version 17.10-ce ?

Don't specify login_email it has been removed from Docker client in 17.10.

[kelein]

Thanks for you reply, I have removed the login_email variable in my packer build json file, then it build successfully with docker 17.10 CE. 👍

The docker new version realeas note says that:
Remove deprecated --email flag from docker login #docker/cli/143

[rickard-von-essen]

I think it's about time that we remove this flag.
