Could not find a required file for docker build - docker

Question

I keep getting a Could not find a required file for my docker build and I am not sure why. I am new to docker so is there a way I can "step through" the build process? I am running
docker build .
when I am INSIDE the /redribbon-client directory
output:
$ docker build .

You will need to copy the public folder over as well. The error stated that it was trying to look for public folder
Could not find a required file.
Name: index.html
Searched in: /client/public
Can you try again with the new Dockerfile?
FROM node:alpine as builder
WORKDIR "/client"
COPY ./package.json .
RUN npm install
COPY ./src/ .
COPY ./public/ .
RUN npm run start
Alternatively, you can copy everything over like this: COPY . .
