Summary

This pull request introduces Docker support by setting up a ROS Noetic environment with GPU acceleration. The changes include the addition of dockerfiles along with a compose script and a new docker usage section in the README.

The following files have been added,

1. nvidia-ros-noetic.Dockerfile

• Builds a ROS Noetic image using an NVIDIA CUDA-based Ubuntu base image.
• Provides GPU acceleration for ROS applications.

2. dev-overlay.Dockerfile

• Extends the ROS Noetic base image to create a development container.
• Includes volume-mounted support for the src folder.

3. docker-compose.yaml
   Simplifies launching of the development environment.

Usage instructions

1. Build the base and development images.

  docker build -f docker/nvidia-ros-noetic.Dockerfile -t nvidia-ros-noetic .
  docker build -f docker/dev-overlay.Dockerfile -t dev-overlay .

2. Launch the development environment.

  xhost +
  docker compose up

3. Access the running container and run a roslaunch command.

  docker exec -it dev-overlay bash

  # Run command inside container
  roslaunch me5413_world world.launch
