Google Cloud Platform

Camp22 Stable-Diffusion Project

GCP deployment diagram

Cloud Compute

Machine Type: n1-standard-4, 4 vCPU, 15GB memory, Nvidia Tesla T4 GPU

Details: Stable Diffusion Dream Fork on Linux

Cost: The cost of running a VM with a GPU is fairly substantial.

Cloud Run

Machine Type: 1GB memory, 1 vCPU, 0-4 instance, running a docker container

Details: Cloud Run runs our spring boot backend connecting between the flutter app and the stable diffusion image generator. The backend has a database that saves the prompt and some other image metadata to be served to the frontend.

Cloud SQL

Machine Type: PostgreSQL 14.4, 1vCPU, 3.75GB memory, 100GB storage

Details: We use a managed Postgres database to store image metadata such as the prompt, seed, user that created the image and whether they chose to publish it.

Artifact Registry

Details: Artifact registry is used to provide a docker registry for our backend. Docker images are built and published to the repository via GitHub actions.

Notes

• See Compute Engine Startup Script Output:

  sudo journalctl -u google-startup-scripts.service

• Nohup: Keep application running in background even when disconnected: nohup CMD &

• Export GCP project as terraform infrastructure as code (IAC)

• Deploy dockerized application via GitHub Action to Google Cloud Run
