Just to run once:

npx --yes @flydotio/dockerfile@latest

Example

# syntax = docker/dockerfile:1
 
# Adjust NODE_VERSION as desired
ARG NODE_VERSION=20.11.1
FROM node:${NODE_VERSION}-slim as base
 
LABEL fly_launch_runtime="Vite"
 
# Vite app lives here
WORKDIR /app
 
# Set production environment
ENV NODE_ENV="production"
 
# Install pnpm
ARG PNPM_VERSION=8.15.4
RUN npm install -g pnpm@$PNPM_VERSION
 
 
# Throw-away build stage to reduce size of final image
FROM base as build
 
# Install packages needed to build node modules
RUN apt-get update -qq && \
    apt-get install --no-install-recommends -y build-essential node-gyp pkg-config python-is-python3
 
# Install node modules
COPY --link package.json pnpm-lock.yaml ./
RUN pnpm install --frozen-lockfile --prod=false
 
# Copy application code
COPY --link . .
 
# Build application
RUN pnpm run build
 
# Remove development dependencies
RUN pnpm prune --prod
 
 
# Final stage for app image
FROM nginx
 
# Copy built application
COPY --from=build /app/dist /usr/share/nginx/html
 
# Start the server by default, this can be overwritten at runtime
EXPOSE 80
CMD [ "/usr/sbin/nginx", "-g", "daemon off;" ]

Thanks
