How to use

Prerequisite

1. Install: brew install socat

2. Install: brew install xquartz

3. Run: open -a XQuartz

4. Setting: XQuartz Preferences -> Security -> check allow all (Allow connections from network clients)

5. Run: defaults write org.macosforge.xquartz.X11 enable_iglx -bool true

6. Run: IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')

7. Run: xhost + $IP

8. Install VirtualBox and its Extension pack

9. Create new docker-machine environment using VirtualBox like below:

   docker-machine create -d virtualbox \
   	--virtualbox-cpu-count=2 \
   	--virtualbox-memory=2048 \
   	--virtualbox-disk-size=100000 \
   	--virtualbox-boot2docker-url https://github.com/gzupark/boot2docker-webcam-mac/releases/download/18.06.1-ce-usb/boot2docker.iso \
   	${YOUR_DOCKER_MACHINE_ENV_NAME}

10. Run: docker-machine stop ${YOUR_DOCKER_MACHINE_ENV_NAME}

11. Configure the VirtualBox image that you created

    • Display -> Video memory (max)
    • Display -> Acceleration -> Enable 3D acceleration (check)
    • Ports -> USB -> Enable USB controller (check) -> USB 2.0 (select)
    • Shared folders -> Add -> Folder Path set root path = / or Folder name you want

Follow steps

• To run below steps everytime when you want to use webcams with docker
• Assume normal terminal session is T1, and XQuartz terminal or 2nd terminal session is T2

1. Run T1: open -a XQuartz
2. Run T2: socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
   • if it occurs an error, please check with lsof -i tcp:6000 and kill the PID
3. Run T1: IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
4. Run T1: xhost + $IP
5. Run T1: docker-machine start ${YOUR_DOCKER_MACHINE_ENV_NAME}
6. Run T1: eval $(docker-machine env ${YOUR_DOCKER_MACHINE_ENV_NAME})
7. Run T1: vboxmanage list webcams and check a list
8. Run T1: vboxmanage controlvm "${YOUR_DOCKER_MACHINE_ENV_NAME}" webcam attach .1 or others referenced a list

Test - XQuartz

• xeyes

  docker run --rm -it -e DISPLAY=$IP:0 gns3/xeyes

• firefox

  docker run --rm -it -e DISPLAY=$IP:0 -v /tmp/.X11-unix:/tmp/.X11-unix jess/firefox

Run - example

docker run --rm -it --device=/dev/video0:/dev/video0 \
	-v /tmp/.X11-unix:/tmp/.X11-unix \
	-e DISPLAY=$IP:0 \
	${YOUR_DOCKER_IMAGE}
