Windows Docker Instruction

Download and install Docker Desktop for Windows. You will be asked to log out to complete the installation.

After installation is completed, enable Docker Backend for WSL 2.

Once completed, verify Ubuntu have access to docker commands.

wsl-user@host:~$ docker --version
Docker version 20.10.17, build 100c701

You would probably want to test NVIDIA accessibility, if applicable.

wsl-user@host:~$ docker run --rm --gpus all nvidia/cuda:11.0.3-base-ubuntu20.04 nvidia-smi

This may have an impact on ROS depending on your usage. See ROS (Docker) Hardware Acceleration.

Now is also a good time to define Docker resources, defined by .wslconfig under your user directory on Windows. See Advanced settings configuration in WSL. Mine is placed at C:\Users\my_user_name\.wslconfig and looked something like this:

[wsl2]

# How much memory to assign to the WSL 2 VM.
# Default to 50% of total memory on Windows or 8GB, whichever is less;
# on builds before 20175: 80% of your total memory on Windows
memory = 16GB

# How many processors to assign to the WSL 2 VM.
# Default is the same number of processors on Windows
processors = 6

You would need to restart WSL backend for this to take effect, simply shut it down and reopen another WSL terminal.
