The attached file is the html rendering of a Jupyter notebook version of Cactus tutorials advocated by Ian and Roland. It is my proposal to use this going forward.
To run this tutorial, you can either go to the NDS machine (which I propose should be the default tutorial machine from now on): https://www.einsteintoolkit.nationaldataservice.org/#/
Alternatively, you may run it in docker.
docker run --name myjupyter -d -p 8888:8888 ndslabs/jupyter-et
If you don't like Jupyter, you can open a console on the NDS machine, or you can get a command line interface by doing this
docker run -it ndslabs/jupyter-et bash
Which is a machine that already has the requisite cactus packages installed. You can then use the attached html to enter instructions one by one.
Please send comments, flames, etc. Thanks.
