React on Kubernetes Ingress

Question

I deployed an application in Azure Kubernetes. I was trying to access the application through the Ingress Nginx controller. The Ingress is pointing to xxx.xxx.com and the app is deployed in the path "/react". So when I accessed the application I am able to see the title but I see the following the console GET https://dns/static/css/main.c0f79ebd.css net::ERR_ABORTED 404. I was able to access the CSS files when I accessed it through https://dns/react/static/css/main.c0f79ebd.css . So how can I add /react to the generated files path?

Following is the dockerfile content

# build environment
FROM node:12.2.0-alpine as build
WORKDIR /app
ENV PATH /app/node_modules/.bin:$PATH
COPY package.json /app/package.json
RUN npm install --silent
RUN npm install react-scripts@3.0.1 -g --silent
COPY . /app
RUN npm run build

# production environment
FROM nginx:1.16.0-alpine
COPY --from=build /app/build /usr/share/nginx/html
RUN rm /etc/nginx/conf.d/default.conf
COPY nginx/nginx.conf /etc/nginx/conf.d
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

If you're using Create React App, you might need to update the 'homepage' setting to reflect that the files will be served from a subdirectory rather the site root.

Putting "homepage": "https://dns/react" in your package.json and rebuilding react/docker and redeploying might do the trick.
