How to Use the Template

Prerequisites

Before using this template, make sure you have the following prerequisites installed on your system:

• Docker
• VSCode
• VSCode Remote Containers Plugin

Getting Started

Step 1: Get the Template

Step 2: Create Your Own Project Repository

Step 3: Clone the Project to Your Computer

Step 4: Open the Folder in VSCode

To interact with the container, you need to install the Docker extension in VSCode. Follow the steps below:

Step 5: Build the Container

You can build the container for the first time by following the steps presented in the following picture.

Please note that if you're on Windows, ensure that Docker Engine is running in the background. The initial build may take some time.

Test your container

To test your contrainer and also the Gazebo installation you can run the following commands in the terminal.

cd
cd PX4-Autopilot/
make px4_sitl gz_x500

This set of commands should open a Gazebo Tab display a drone as presented in the following figure. If the command is not displaying a tab, you should refer to the FAQ section of this readme to set up a X server.

FAQ

WSL2

The gui doesn't show up

This is likely because the DISPLAY environment variable is not getting set properly.

1. Find out what your DISPLAY variable should be

   In your WSL2 Ubuntu instance

   echo $DISPLAY
   

2. Copy that value into the .devcontainer/devcontainer.json file

   	"containerEnv": {
           "DISPLAY": ":0",
      }

I want to use vGPU

If you want to access the vGPU through WSL2, you'll need to add additional components to the .devcontainer/devcontainer.json file in accordance to these directions

	"runArgs": [
		"--network=host",
		"--cap-add=SYS_PTRACE",
		"--security-opt=seccomp:unconfined",
		"--security-opt=apparmor:unconfined",
		"--volume=/tmp/.X11-unix:/tmp/.X11-unix",
		"--volume=/mnt/wslg:/mnt/wslg",
		"--volume=/usr/lib/wsl:/usr/lib/wsl",
		"--device=/dev/dxg",
      		"--gpus=all"
	],
	"containerEnv": {
		"DISPLAY": "${localEnv:DISPLAY}", // Needed for GUI try ":0" for windows
		"WAYLAND_DISPLAY": "${localEnv:WAYLAND_DISPLAY}",
		"XDG_RUNTIME_DIR": "${localEnv:XDG_RUNTIME_DIR}",
		"PULSE_SERVER": "${localEnv:PULSE_SERVER}",
		"LD_LIBRARY_PATH": "/usr/lib/wsl/lib",
		"LIBGL_ALWAYS_SOFTWARE": "1" // Needed for software rendering of opengl
	},

Repos are not showing up in VS Code source control

This is likely because vscode doesn't necessarily know about other repositories unless you've added them directly.

File->Add Folder To Workspace

Or you've added them as a git submodule.

To add all of the repos in your *.repos file, run the script

python3 .devcontainer/repos_to_submodules.py

or run the task titled add submodules from .repos
