Dockerfile Generator

Purpose

• Produce a multi-stage Dockerfile that builds the Vite project and serves the generated dist with nginx (recommended) or any static server.

Example prompts

• "create Dockerfile for production build"
• "generate multi-stage Dockerfile with nginx"

Sample Dockerfile

# builder
FROM node:18-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --production=false
COPY . .
RUN npm run build

# production image
FROM nginx:stable-alpine
COPY --from=builder /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

Notes

• If the app needs server-side APIs, recommend building a separate backend image and using docker-compose.
• Provide guidance for VITE_BASE_URL or --base during build if app is served from a subpath (e.g., GitHub Pages).
• Suggest using build cache layers (copy package.json first) to speed CI builds.
