Script ROS to start at boot

edit

I'm following the http://wiki.ros.org/roslibjs/Tutorial... example and running it in docker container.

It works if I manually type in the three commands by hand

1. roscore &
2. rosrun actionlib_tutorials fibonacci_server &
3. roslaunch rosbridge_server rosbridge_websocket.launch

but now I'd like to start the server automatically when the container runs.

I tried to make a script with those 3 commands and call it once the container is booted, but it doesn't work. It seems maybe some of the later commands are being run before the earlier ones finish whatever it is they're doing.

I can make it work by adding sleep 10 commands between the ros commands, but that doesn't seem like a good solution. What happens if something takes longer than 10 seconds to start?

Is there a proper way to script ROS so that you don't have to manually type in commands? Would it involve systemd? I saw some answers talk about upstart, but that's not used much anymore.

Thanks
