Generating the Custom Illustrations (pca-image-prompts.json)

All 190 custom image prompts and output filenames for this book are stored in pca-image-prompts.json (and mirrored in openai-image-gen/out/9005-openai-prompts-pca-book.json). To generate the illustrations using openai-image-gen/images-from-prompts.py, run:

cd openai-image-gen
uv run images-from-prompts.py -file ../books/pca-architecture-takeaways/pca-image-prompts.json -simple -quality medium

The approach taken is a question-led learning approach: you explore realistic project scenarios where you need to make decisions or take actions to achieve business goals within specific constraints. Instead of passive learning, you are challenged to think and work through the options to master the Professional Cloud Architect (PCA) certification!
