Cloud Run

Google Cloud Run is a managed compute platform that automatically scales your containers.

Status: Experimental

Features

• Container-Based: Runs standard OCI containers
• Auto-Scaling: Scales to zero and up based on traffic
• HTTP/2: Full HTTP/2 support
• Long-Running: Supports long execution times
• Google Cloud Integration: Access to GCP services

Project Setup

Generate a new Cloud Run project:

uzumibi new --template cloudrun my-app
cd my-app

Configuration

The project includes a Dockerfile for containerization:

FROM rust:1.75 as builder
WORKDIR /app
COPY . .
RUN cargo build --release

FROM debian:bookworm-slim
COPY --from=builder /app/target/release/my-app /usr/local/bin/my-app
CMD ["my-app"]

Local Development

# Build and run locally
cargo run

The server will start on http://localhost:8080.

Deployment

# Build container
gcloud builds submit --tag gcr.io/PROJECT_ID/my-app

# Deploy to Cloud Run
gcloud run deploy my-app \
  --image gcr.io/PROJECT_ID/my-app \
  --platform managed \
  --region us-central1 \
  --allow-unauthenticated

Limitations

• Cold Start: Higher cold start latency compared to edge platforms
• Cost: Billed per request and compute time
• Not Edge: Runs in regional data centers, not at the edge
