Stable Diffusion on Google Cloud Platform using Pulumi

Requirements

• Python 3
• Pulumi, https://www.pulumi.com/docs/get-started/install/

Instructions

1. Create a service account in Google Cloud Platform as follows:

   • Log in to the Google Cloud Console (console.cloud.google.com)
   • Select the project in which you want to create a service account
   • Click on the "IAM & Admin" option in the left-hand menu
   • Click on "Service Accounts" in the left-hand menu
   • Click the "Create Service Account" button
   • Enter a name for the service account
   • Select "Editor" role for the service account
   • Select "Furnish a new private key" option and choose JSON
   • Click "Create" to create the service account
   • Once you have created the service account, you will be prompted to download the private key file

2. Rename service account private key file to gcp.json and place it inside the /infra directory

3. Rename .sample.env to .env and edit its contents

4. Execute in your terminal ./start.sh to:

   • Enable Google Cloud Services
   • Build and push a Docker image to Google Container Registry
   • Spin up a Kubernetes cluster running a A100 GPU
   • Install NVIDIA driver into Kubernetes cluster
   • Launch the Stable Diffusion Kubernetes deployment
   • Expose Stable Diffusion to the public internet using a Kubernetes Service

How to use

Once ./start.sh finishes running it will output load_balancer_ip, for example: load_balancer_ip: "34.172.48.137". Use the IP provided to query Stable Diffusion.

Parameters:

prompt=args.get("prompt", "a professional photograph of an astronaut riding a triceratops"),
outdir=args.get("outdir", "static"),
steps=args.get("steps", 50),
plms=args.get("plms", False),
dpm=args.get("dpm", False),
fixed_code=args.get("fixed_code", False),
ddim_eta=args.get("ddim_eta", 0.0),
n_iter=args.get("n_iter", 3),
H=args.get("H", 512),
W=args.get("W", 512),
C=args.get("C", 4),
f=args.get("f", 8),
n_samples=args.get("n_samples", 3),
n_rows=args.get("n_rows", 0),
scale=args.get("scale", 9.0),
from_file=args.get("from_file", None),
config=args.get("config", "configs/stable-diffusion/v2-inference-v.yaml"),
ckpt=args.get("ckpt", "checkpoints/v2-1_768-ema-pruned.ckpt"),
seed=args.get("seed", 42),
precision=args.get("precision", "autocast"),
repeat=args.get("repeat", 1),
device=args.get("device", "cpu"),
torchscript=args.get("torchscript", False),
ipex=args.get("ipex", False),
bf16=args.get("bf16", False)

For example: http://34.172.48.137/?prompt=Your_Query_Here. Replace Your_Query_Here with your desired query text.

To check the generated images navigate to http://34.172.48.137/images.

Remember to URL-encode the text parameter if it contains special characters or spaces. For example, you can replace spaces with %20.

Delete cluster and revert all changes

To delete the cluster and revert all changes, execute in your terminal: ./destroy.sh.
