How to deploy React + Nginx on AWS ECS (FARGATE)

For this example I will use Vite to create the React project



npm create vite@latest frontend -- --template react-ts

Dockerfile



FROM nginx:latest

EXPOSE 80

# Frontend with production files

COPY  ./frontend/dist /usr/share/nginx/html

Publish Image to Docker Hub



# BUILD FRONTEND

cd ./frontend && npm run build && cd ..

docker login -u $DOCKER_USER -p $DOCKER_PASSWORD

docker build . -t $DOCKER_USER/react-app:latest

docker push $DOCKER_USER/react-app:latest
