Luxonis Docker

https://hub.docker.com/u/luxonis

Run

luxonis/luxonis-os-rvc4:1.39.1-public

First terminal — start it, and give it a name so it's easy to reference

docker run --rm -it --privileged --name rvc4-dev --entrypoint bash \
  luxonis/luxonis-os-rvc4:1.39.1-public \
  -c "source /prepare-env.sh && exec bash"

Second terminal — attach a new shell to that same running container

docker exec -it rvc4-dev bash

The typical workflow for the user:

1. Bind-mount the project into the container and prepare the env

docker run --rm -it --privileged --entrypoint bash \
  -v ~/myproject:/workspace \
  luxonis/luxonis-os-rvc4:1.39.1-public \
  -c "source /prepare-env.sh && exec bash"

2. Inside the container, build from workspace

cd /workspace
cmake -B build -S .
make -C build

3. Artifacts land back in ~/myproject via the bind mount

scp ~/myproject/my-built-binary root@<rvc4-device-ip>:/usr/bin/
ssh root@<rvc4-device-ip> "chmod +x /usr/bin/my-built-binary && /usr/bin/my-built-binary"
