Step 1) 安装 XQuartz，允许网络连接

GoCoding!GoCoding!GoCoding!GoCoding!GoCoding!

# 安装
brew cask install xquartz
# 运行
open -a xquartz

1. 进入 "Preferences > Security"
2. 勾选 "Allow connections from network clients"

Step 2) 安装 Docker，准备相关镜像

brew cask install docker
# 或，直接下载再安装：
#   https://download.docker.com/mac/stable/Docker.dmg

拉取 OpenCV 镜像，用其显示：

docker pull joinaero/anaconda3-opencv3:1.0.0

Step 3) xhost 添加主机 IP

GoCoding!GoCoding!GoCoding!GoCoding!GoCoding!

# 获取 IP
IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
echo $IP

# 增加 IP
xhost + $IP

Step 4) OpenCV 预览图片

XQuartz, xterm 继续执行：

docker run -it --rm \
  --name myenv \
  -e DISPLAY=$IP:0 \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  joinaero/anaconda3-opencv3:1.0.0

conda activate myenv

python - <<EOF
import cv2
while True:
  im = cv2.imread("/tmp/GoCoding.png")
  im = cv2.resize(im, (256, 256))
  cv2.imshow("GoCoding", im)
  key = cv2.waitKey(10) & 0xFF
  if key == 27 or key == ord('q'):
    break
EOF

预览效果如下：
