An Alpine Linux based mini Tcl for Docker.
This contains a restricted set of packages necessary for running Tcl 8.6 applications. It is based on an installation of the packages available in Alpine Linux, and an install of the latest tcllib. That should leave you with tls, expect, all the Tcl 8.6 packages (threads, database connections, etc.) and the whole of the tcllib. The pure-tcl readline is enabled by default for the root user in the container so you will have a decent prompt at the command line.
Building and Running
To build, simply write:
docker build -t efrecon/mini-tcl .
To run and get an interactive Tcl prompt:
docker run -it --rm efrecon/mini-tcl
Running your own scripts
This image exports
/opt/tcl as a volume and arranges to give that
directory and its sub-directory
lib as additional locations when
looking for packages. This means that you should be able to mount
local directories onto
/opt/tcl to run your own code within the
Additionally, the image exports
/opt/data to place random data that
you might wish to access from within the container.
