Create statically built Create React App applications docker images for easy deployment with environment variables support at runtime.

This project was created to solve known problem with CRA in favor of 12 factor apps. See facebook/create-react-app#2353

All you need to do is get the content of built app (build folder) inside docker image in /app folder.

To get this working firstly create Dockerfile in your project root with content:

FROM inloopx/cra-docker

COPY build /app

then you can call:

# or npm run build
yarn build
docker build -t my-new-app .

Once the build is done, you should have your image ready. To verify it, run the image bind to 8080 port:

docker run --rm -p 8080:80 my-new-app

Now if you open http://localhost:8080 You should see your app.

You can find more in example directory. Also if you use gitlab, don't miss the pipeline configuration file example
