# Fly.io Deploy Integration ## Overview Deploy edge applications on Fly.io with Docker containers and the `fly.toml` configuration file. This skill covers building production images optimized for Fly's micro-VM architecture, configuring `fly.toml` for services, health checks, and multi-region placement, verifying API connectivity from edge locations, and executing rolling updates with automatic rollback. Fly.io deploys as Firecracker micro-VMs, so containers start in under a second and scale to zero when idle. ## Docker Configuration ```dockerfile FROM node:20-slim AS builder WORKDIR /app COPY package*.json ./ RUN npm ci COPY tsconfig.json ./ COPY src/ ./src/ RUN npm run build FROM node:20-slim RUN addgroup --system app && adduser --system --ingroup app app WORKDIR /app COPY --from=builder /app/dist ./dist COPY --from=builder /app/node_modules ./node_modules COPY package*.json ./ USER app EXPOSE 8080 CMD ["node", "dist/index.js"] ``` ## Fly.io Configuration ```toml # fly.toml app = "my-integration" primary_region = "iad" [build] dockerfile = "Dockerfile" [env] LOG_LEVEL = "info" PORT = "8080" [http_service] internal_port = 8080 force_https = true auto_stop_machines = true auto_start_machines = true [[http_service.checks]] interval = "30s" timeout = "5s" grace_period = "10s" method = "GET" path = "/health" ``` ## Environment Variables ```bash export FLY_API_TOKEN="fo1_xxxxxxxxxxxx" fly secrets set FLYIO_APP_NAME="my-integration" fly secrets...
