This is an example of deploying a React app's production build to an Nginx server. If you're deploying inside a cloud instance (such as AWS EC2), this method helps reduce the resources used on the server.

Docker

FROM node:18 AS build
WORKDIR /opt/{your app name}
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build --build-arg CACHEBUST=${CACHEBUST}
FROM nginx:latest
COPY --from=build /opt/{your app name}/build /usr/share/nginx/html
EXPOSE 81
COPY nginx.conf /etc/nginx/nginx.conf
CMD ["nginx", "-g", "daemon off;"]
