Pull request overview
This PR re-enables generation of visual Spack environment dependency graphs during the containers/eic image build by producing a transitively-reduced DOT graph (via tred) and rendering it to SVG and PNG (via dot). This fits the repo’s goal of producing self-describing EIC container images by embedding build artifacts and environment metadata in the resulting image.
Changes:
- Generate a transitively-reduced Spack dependency graph (
env_tred.dot) fromspack graph --dotoutput. - Render the reduced graph to
/opt/spack-environment/env.svgand/opt/spack-environment/env.pngduring the image build.

Briefly, what does this PR introduce? Please link to any relevant presentations or discussions.
We previously stopped spack package graph conversion to svg and png due to time needed to find a drawing solution. With
tredwe can do a transitive reduction of the graph, which is then tractable for drawing in seconds. So, now we generate a pretty picture.What is the urgency of this PR?
