I have built a structure for a microservice app. auth is the first Dockerfile I have made and as far as I can tell is not building.
C:\Users\geeks\Desktop\NorthernHerpGeckoSales\NorthernHerpGeckoSales\auth>docker build -t giantgecko/auth .

Could you share more details on your Dockerfile? But based on your error, it seems it stopped on the COPY stage. You need to provide the <source> and the <destination>.
Here's an example based on your error:
WORKDIR /app
COPY /Users/geeks/Desktop/NorthernHerpGeckoSales/NorthernHerpGeckoSales/auth /app/auth
By default, all files will be copied under the WORKDIR
you can checkout official documentation of Dockerfile here https://docs.docker.com/engine/reference/builder/#copy

I was able to resolve this by changing my Dockerfile to:
FROM node:alpine
WORKDIR /app
COPY package.json .
RUN npm install
COPY . .
CMD ["npm", "start"]
The fix came after I changed COPY from the absolute path to . ., and cleared the npm cache with npm cache clean -f.
