Basically, you have three options.

1. Write your own "planner" that follows the path. This can actually be a simple controller without any collision avoidance and should be straightforward.
2. You can write a GlobalPlannerPlugin to move_base that subscribes to the path you create (or creates it itself) and then passes it down to the local planner. There are quite some questions about this (e.g. here or here). Then you have the full capabilities of move_base available later on
3. Use move_base_flex. This exposes additional actions which should let you do what you want directly. See this question for details.

I personally have done 1 (pretty easy) and 2 (works quite will). EVen though I haven't tested it, I'd say 3 would be the way to go now (though move_base_flex is currently still not very stable, but quite actively developed).
