With respect to roosters, I do not agree dominance training is required or optimal for interspecific interactions with human keeper. I keep a good number of game roosters and smaller numbers of American dominiques. When all works as desired the birds do not even regard you as being within the pecking order continuum. You are an obstruction, something that might step on them, a source of food, and / or a force they can call upon to deal with threats but need not be their boss or subordinate.
OP's bird has not been defined in respect to age. Age is extremely important in respect to how minimizing aggression can be achieved.
Treating a motivated rooster like a dog can easily create a man-figher. With young birds in particular, I ignore aggression since no real harm is done. If a bird is persistant with his aggression, then I give him the opportunity to wear himself out or get bored with attacks. No response by me is shown and bird seems to think attacking me is a akin to attacking something inanimate like a lawnmower. Recoil; bird will think he can beat you. Counter attack; he may up the stakes and begin treating you as a threat which is not another rooster. If you go the pecking order route, be prepared have repeat your aggression to keep him in his place as it is his job to test you and turning your back on him will be a sign of weakness or stupidity he can not fail to take advantage of.
