Reference: X11 in docker on macOS

1. Install XQuartz from official website or through Homebrew

   $ brew install --cask xquartz

   and then Restart OS.

2. Open XQuartz and Check the option: XQuartz -> Preferences -> Security -> "Allow connections from network clients"

   # open XQuartz
   $ open -a XQuartz

3. In terminal:

   # Expose the X server on the host
   $ xhost  localhost

   Creating a bridge between a network socket with a TCP listener on port 6000 (the default port of the X window system) and the X window server on my OS X host.

   $ socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
   

   $ docker run --rm -it \
       -e DISPLAY=host.docker.internal:0 \
       -e QT_X11_NO_MITSHM=1 \
       -e QT_QUICK_BACKEND=software \

1. libGL error: No matching fbConfigs or visuals found

   $ export LIBGL_ALWAYS_INDIRECT=1

   Workaround:

   $ export QT_QUICK_BACKEND=software

3. Miniconda install issue:

   • Install Python3.8, ModuleNotFoundError: No module named 'conda.cli.main_info'

     comment `conda update -n base conda`
     

   2022/12/6 update: If the old command has error, we can replace it as below:

   # Install miniconda for python 3.8
   ENV PYTHON_VERSION="3.8"
   ENV CONDA_PATH="/usr/local/anaconda3"
   ENV MINICONDA_FILE="Miniconda3-py38_4.12.0-Linux-x86_64.sh"
   RUN wget https://repo.continuum.io/miniconda/${MINICONDA_FILE} && \
       sh ${MINICONDA_FILE} -b -p ${CONDA_PATH} && \
       ${CONDA_PATH}/bin/conda update -n base conda && \
       ${CONDA_PATH}/bin/conda install python=${PYTHON_VERSION} && \
       ${CONDA_PATH}/bin/conda clean -y -a && \
       rm -rf ${MINICONDA_FILE} && \
       rm -rf /temp/*
