    Node.js / Express Dockerfile for Oracle Cloud ARM

    A plain Node API with persistent memory, cron and WebSockets — no per-invocation billing. Built for Ampere A1 (arm64), listens on port 3000, and starts with node src/index.js.

    Dockerfile
    FROM node:22-alpine
WORKDIR /app
ENV NODE_ENV=production
COPY package*.json ./
RUN npm ci --omit=dev
COPY . .
EXPOSE 3000
CMD ["node", "src/index.js"]

    ARM notes for Node.js / Express

    Node ships official ARM64 images. Native modules (bcrypt, sharp, better-sqlite3) compile fine on Ampere but add build time — prefer prebuilt or pure-JS alternatives where you can.

    Skip the build, network and TLS setup

    Cheaploy builds this image on your own Oracle Always Free VM, opens the ports, issues HTTPS and rolls back if health checks fail.
