Mac: Run ubuntu command with GUI in docker

Step 1: create Dockerfile

FROM ubuntu:22.04

# Install xclock and necessary X11 libraries
RUN apt-get update && apt-get install -y \
    x11-apps \
    && rm -rf /var/lib/apt/lists/*

# Set the DISPLAY environment variable
ENV DISPLAY=host.docker.internal:0

# Run xclock
CMD ["xclock"]

Step 2: Build the image

docker build -t xclock-ubuntu .

Step 3: Set XQuartz and restart it

Step 4: Run "xhost + 127.0.0.1", and this "xhost +localhost" wont work

Step 5: Run

docker run --rm \
    -e DISPLAY=host.docker.internal:0 \
    xclock-ubuntu

Another way

docker run --name test -it ubuntu
apt-get update
apt-get install x11-apps
export DISPLAY=host.docker.internal:0
xclock
