reactjs dist in docker faviconico 404

To resolve the favicon.ico 404 error in a React.js application running in a Docker container, you can follow these steps:

1. Create a public folder in the root directory of your React.js project if it doesn't already exist.

2. Place the favicon.ico file inside the public folder.

3. Update the Dockerfile to include the COPY command to copy the public folder into the container.

   # Dockerfile
   FROM node:14-alpine
   
   WORKDIR /app
   
   COPY package*.json ./
   
   RUN npm install
   
   COPY . .
   
   # Add the following line
   COPY public ./public
   
   EXPOSE 3000
   
   CMD ["npm", "start"]
   

4. Rebuild the Docker image and run the container again.

   docker build -t my-react-app .
   docker run -p 3000:3000 my-react-app
   

Now, the favicon.ico file should be accessible without any 404 errors.
