This project aims to provide a data and control bridge for the communication between Carla and Apollo. It was tested with Carla 0.9.14 and the Apollo master branch (newer than v7.0.0)

We will run Carla and Apollo in docker. Furthermore, NVIDIA Container Toolkit is needed. You can refer to the following link to install NVIDIA Container Toolkit:

• https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html

Alternatively, simply perform the following steps：

• docker

  sudo apt-get install docker.io

• NVIDIA Container Toolkit

  curl https://get.docker.com | sh \
  && sudo systemctl --now enable docker

  distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
      && curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
      && curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \
            sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
            sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

  sudo apt-get update

  sudo apt-get install -y nvidia-docker2

  sudo systemctl restart docker

1. We patched Apollo in order to work with our bridge, for now please use the guardstrike/apollo_carla_bridge branch from our fork.

   # Using SSH
   git clone --branch guardstrike/apollo_carla_bridge [email protected]:guardstrikelab/apollo.git
   
   #Using HTTPS
   git clone --branch guardstrike/apollo_carla_bridge https://github.com/guardstrikelab/apollo.git

   We will be sending this patch upstream soon so that you can just clone the official Apollo next time.

2. Build Apollo

   cd apollo
   echo "export APOLLO_ROOT_DIR=$(pwd)" >> ~/.bashrc  && source ~/.bashrc

   Then, run:

   bash docker/scripts/dev_start.sh

   to start Apollo development docker container.
   If you encounter any error, try

   sudo rm -rf /apollo/.cache
   bash docker/scripts/dev_start.sh

   Upon successful execution, you will see the following message

   [ OK ] Congratulations! You have successfully finished setting up Apollo Dev Environment.
   [ OK ] To login into the newly created apollo_dev_lei container, please run the following command:
   [ OK ]   bash docker/scripts/dev_into.sh
   [ OK ] Enjoy!

   Above If you occured error as "ERROR: Config value 'cuda' is not defined in any .rc file",you can try

   ./apollo.sh config -n

   Run this command to enter the container

   bash docker/scripts/dev_into.sh

   Make the GPU version:

   ./apollo.sh build_gpu

   After successful compilation, the following will be printed:

   ==============================================
   [ OK ] Done building apollo. Enjoy!
   ==============================================

   Run this command in the container to start Dreamview

   ./scripts/bootstrap.sh

   Finally, open the link in your browser

   http://localhost:8888/

• Clone the carla_apollo_bridge project

  # Using SSH
  git clone [email protected]:guardstrikelab/carla_apollo_bridge.git
  
  #Using HTTPS
  git clone https://github.com/guardstrikelab/carla_apollo_bridge.git

• To download and install Compose standalone, run:

     sudo curl -L "https://github.com/docker/compose/releases/download/v2.0.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

• Change File Permission:

  sudo chmod +x /usr/local/bin/docker-compose 

Apply executable permissions to the standalone binary in the target path for the installation. Test and execute compose commands using docker-compose. Note: If the command docker-compose fails after installation, check your path. You can also create a symbolic link to /usr/bin or any other directory in your path. For example:

 sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

• Pull carla image and run

  cd carla_apollo_bridge/scripts
  ./docker_run_carla.sh

1. Run the following to enter the container. Note that carla_apollo_bridge/src is mapped to /apollo/cyber/carla_bridge within the container, this allows you to test any change you make to the bridge.

   cd carla_apollo_bridge/docker
   ./build_docker.sh
   ./run_docker.sh
   docker exec -ti carla_cyber_0.9.14 bash

2. Compile

   Run the following command in the container

   ./apollo.sh build_cyber opt

   The following information is displayed after the compilation is successful:

   [INFO] Skipping revision recording
   ============================
   [ OK ] Build passed!
   [INFO] Took 61 seconds

3. Start the bridge and spawn the ego vehicle

   Run the following command in the container.

   cd /apollo/cyber/carla_bridge
   python carla_cyber_bridge/bridge.py

   Start a new terminal and run:

   docker exec -ti carla_cyber_0.9.14 bash
   cd /apollo/cyber/carla_bridge
   python carla_spawn_objects/carla_spawn_objects.py

If everything above goes well, you should see this in Apollo client:

and this in Carla:

1. Open apollo client: http://localhost:8888
2. (Optional) Select "Task" in the sidebar and turn on "Camera Sensor" in "Others".
3. (Optional) Select "Layer Menu" in the sidebar and turn on "Point Cloud" in "Perception".
4. Select "Module Controller" in the sidebar and turn on "Routing" module.
5. Select "Route Editing" in the sidebar.
6. Click "Add Point of Interest" and left click at any point on the road to set the destination.
7. Click "Send Routing Request".
8. Select "Tasks" and click "Setup" to start co-simulation.
