Do not attach to that brick wall. Brick and the mortar surrounding it ARE NOT strong enough, by any means to hold:
The dead load weight of the deck materials +
The Live load of the people that will be on it +
The weight of any furniture, grill, plants that you add +
Regular wet weather errosion on the brick and mortar =
You want to attach your deck ledger directly into the house's rim joist using lags or carriage bolts.
Additionally, drilling through that brick would not be a good idea, you would be placing a brittle material (which will erode with wet weather) between your home and your deck. You want solid material between your anchoring systems.
It is also possible to build the deck 'free standing' next to your house: By putting the deck supports all
on concrete pier footings.
