Ulster face a tough trip to the Warriors as the curtain comes down, with the Scottish outfit themselves looking to secure home advantage for the knockouts after Friday's defeat to the Ospreys.
And if Ulster are to set up a potential Kingspan semi-final and final double, Doak admits his men cannot look past the upcoming Scotstoun shootout.
"Our thought process is about going to Glasgow and getting a result," the Ulster boss said.
"Obviously we have to rely on somebody else to do us a favour with Munster and the Ospreys, but we'll be focusing on Glasgow.
"We've got to regroup and make sure that we're ready to go over there and look to get the win.
"To come back and get the draw against Munster showed great character in the squad.
"It was probably a little bit ironic in that we played them earlier in the season and missed a kick to win the game, and we got one here to draw.
"There are four quality sides in the play-offs and I think on the day anybody could beat anybody.
"We have to go to Glasgow now and make sure we shore up on a few areas, try to get another good performance together but hopefully get the result as well."
