# A docker container exits when its main process finishes, which in this case is bash.
# This means that the containers will stop once you exit them and everything will be lost.
# To avoid this use detach mode. More on this in the next paragraph
#
#   - run interactively with all GPUs accessible:
#
#       docker run -it --gpus all mikel-brostrom/yolov5_strongsort_osnet bash
#
#   - run interactively with first and third GPU accessible:
#
#       docker run -it --gpus '"device=0, 2"' mikel-brostrom/yolov5_strongsort_osnet bash


# Run in detached mode (if you exit the container it won't stop)
#
#   -create a detached docker container from an image:
#
#       docker run -it --gpus all -d mikel-brostrom/yolov5_strongsort_osnet
#
#   - this will return a <container_id> number which makes it accessible. Access it by:
#
#       docker exec -it <container_id>
#
#   - When you are done with the container stop it by:
#
#       docker stop <container_id>
