Hello, your Galaxy ToolFactory Docker container is running!

If you have not already done so, From a handy linux console, please use
docker ps
to find this container's name then use
docker exec [container name] config/post-start-actions.sh
to load the sample tool generators to fully populate this container. until the Dockerfile for this container figures out how to load a workflow during the build correctly.
To run the workflow you need two small datasets until I get them loaded
phiX.fasta from the Galaxy test-sample directory, and any smallish text file you want such as a readme or script.
When you run the workflow, feed the fasta where it says, and the text file where you see rgToolFactory.py
Send it to the same history and let it run.
With any luck, you will have a history of examples to play with - use the rerun button to repopulate the ToolFactory form to illustrate
positional and argparse style parameter passing for python, a simple bash script using STDIN/STDOUT and the perl (ugh) example from planemo
