Production

Fly.io​

The project includes a fly.toml configuration. Make sure flyctl is installed and you're logged in.

fly auth login
fly deploy

Docker​

Build and run the production image:

docker build -t epydemix-api .
docker run -p 8000:8000 epydemix-api

Google Cloud Run​

Deploy from source with Cloud Build:

gcloud run deploy epydemix-api --source . --region=us-east1 \
  --cpu=2 --concurrency=2 --max-instances=20 --allow-unauthenticated

The simulation endpoint is CPU-bound, so set --concurrency to match the worker/vCPU count, otherwise requests queue on an overloaded instance instead of scaling out. See Google Cloud Run for the full guide and tuning rationale.

Environment variables​

See Configuration for all available settings.
