Heroku deploys don't use rake. You do git push $REMOTE $REF:master , where $REMOTE is the name of the git remote, or a git URL, and $REF is master, HEAD, or some other commit you want to push.

Also, if you're pushing the current HEAD, you can just do git push $REMOTE master , or, depending on your git config, git push $REMOTE
