This image just installs tasksh out of Ubuntu repositories. It includes a default .taskrc, which sets the data directory to /root/.task.

The most basic run just specifies how the volume for the data (default: /root/.task) is loaded:

docker run -it --rm -v/your/task/directory:/root/.task ulukai/tasksh

You can override the configuration file at /root/.taskrc and, therefore, customize your tasksh:

docker run -it --rm -v/your/task/directory:/root/.task -v/your/taskrc:/root/.taskrc ulukai/tasksh
