Multipaint-container (Multipaint version 8.6.2026)

This is a simple Docker container that allows you to run Multipaint on macOS by encapsulating the application and its dependencies. XQuartz is used to display the GUI.

Prerequisites

• Docker

• XQuartz: after installation, enable "Allow connections from network clients" in the XQuartz security settings and reboot your machine to apply the changes, finally type xhost +localhost in your terminal to allow connections from localhost. Further instructions can be found here.

Quick start

Remember to run (if needed)

xhost +localhost

Use image from Docker Hub to install or update

1. Pull the Docker image

docker pull tznurmin/multipaint:latest

Now you have the container image. In order to load and save your work, you'll mount a directory inside your filesystem. A directory named temp is used in this example: use mkdir name_of_your_directory in terminal to create one.

2. Run the container and mount temp from your current working directory

docker run --rm \
           -e DISPLAY=host.docker.internal:0 \
           -v /tmp/.X11-unix:/tmp/.X11-unix \
           -v "$(pwd)/temp:/app/savedisk" \
           --name multipaint-container \
           tznurmin/multipaint:latest

Or build your own

This builds the latest version, regardless of the version available on Docker Hub.

1. Clone the repository

git clone https://github.com/tznurmin/multipaint-container.git

2. Build the image

cd multipaint-container/df && docker build -t multipaint .

3. Run the container

docker run --rm \
           -e DISPLAY=host.docker.internal:0 \
           -v /tmp/.X11-unix:/tmp/.X11-unix \
           -v "$(pwd)/temp:/app/savedisk" \
           --name multipaint \
           multipaint

Remember to create a directory (e.g. temp) for your images.

Troubleshooting

1. Can't connect to X11 window server using 'host.docker.internal:0' as the value of the DISPLAY variable. Fix it by allowing the connections from localhost

xhost +localhost
