So, no evidence directly from the show that Luna's clan is Floukru and part of the Coalition. There is strong social media evidence that Boat People = Floukru and it being one of the 12 Clans of the Coalition. There is also two non-show evidence that Luna is of the Boat People: a song name and an old "I think" interview.

The link between Boat People and Floukru is explained in a tumblr post by David J. Peterson, the language creator of Trigedasleng. He says "Floudon" means "boat", so the direct translation of "Floudon Kru" is "Boat People". JR has posted on Twitter a list of the 12 Grounder Clans, including "Boat People". Peterson later released on Reddit the Trigedasleng names of the 12 Clans which included "Floudonkru".

In one interview, JR kinda says that Luna is part of the Boat People: "I think [Lincoln] says something about 'the people of the sea' or 'boat people' when he refers to to Luna." Since this was before season 2 (and way before season 3) and JR starts the statement with "I think", I'm not sure how much this can be taken as fact.

Tree Adams, the composer for the show, named one of the songs in the season 3 soundtrack as "Luna of the Boat People". Not sure how far the composer's song names can be taken as fact. On one hand, he's not directly associated with the story telling; on the other hand, where would he have gotten "of the Boat People" if not from the writers.
