The purpose of this is to run /many/ ArduPilot SITL from within Docker.

A pre-built Docker image is available on DockerHub at:

https://hub.docker.com/r/radarku/sitl-swarm

To download it, simply:

docker pull radarku/sitl-swarm

and to run it:

docker run --rm -p 5760-5810:5760-5810 --env NUMCOPTERS=3 radarku/sitl-swarm

If you'd rather build the docker image yourself:

docker build --tag sitl-swarm .

To run the image:

docker run --rm -p 5760-5810:5760-5810 --env NUMCOPTERS=3 sitl-swarm

This will start 3 ArduCopter SITL on host TCP ports 5760, 5770, and 5780; so to connect to it from the host, you could:

mavproxy.py --master=tcp:localhost:5760
mavproxy.py --master=tcp:localhost:5770
mavproxy.py --master=tcp:localhost:5780
