Draft

This documentation is in draft and under active review. Figures for the Fall 2026 GPU reservation system are not yet published, and some pages describe behaviour that has not been verified against a primary source. Check with us before relying on anything here.

Environments

The software images a session runs, what can be added to one, and how to build a new one.


Documented once, and linked from wherever it is needed.

Every page in this directory is an initial draft. Each opens with a note naming what its writer could not settle. Please read those before treating any page as final.

Page Covers
Standard Images, Tags & Pinning The three maintained images, how they inherit, tag forms, and holding a course on one build.
Customizing an Environment Installing into a home directory, private kernels, R libraries — and the boundary at root.
Building & Publishing a Custom Image A Dockerfile, a base image, and testing the result on DSMLP.
