Missing image name in chapter 2

[raskolnikov7]

I'm reading the book on safaribooksonline
In chapter 2 'docker run' command to start the mailer container :

docker run -d
--name mailer \

the image name (dockerinaction/ch2_mailer) is missing

I actually get a 'requires at least one argument ' error
