In ROS1 you could loop play using the -l command.

However, it appears that this has not been implemented yet in ROS2.

You can follow the development of rosbag for ROS2 here https://github.com/ros2/rosbag2

I can't mark your answer as correct even though it is :) rosbag2 doesn't have capabilities yet to play the data in a loop.

The option has been implemented in April 2020 (https://github.com/ros2/rosbag2/commi...)

Use the -l (or --loop) option:

ros2 bag play <bagfile.db3> --loop

I simply use loop in batch file:

FOR /L %%A IN (1,1,10) DO ( ECHO %%A ros2 bag play <path to rosbag> )
