Connecting to Docker Hub

How can we connect to hub.docker.com?
docker::registry { 'hub.docker.com':
username => 'user',
password => 'password'
}

/Stage[main]/Main/Docker::Registry[hub.docker.com]/Exec[hub.docker.com auth]/returns: Error: Cannot perform an interactive login from a non TTY device

Looked at the code : if $ensure == 'present' {
if $username != undef and $password != undef and $email != undef {
$auth_cmd = "${docker_command} login -u '${username}' -p "${password}" -e '${email}' ${server}"
$auth_environment = "password=${password}"
}
elsif $username != undef and $password != undef {
$auth_cmd = "${docker_command} login -u '${username}' -p "${password}" ${server}"
$auth_environment = "password=${password}"
}

not sure why it does not go in elsif block
