I'm using a multi-stage builds within my dokcerfile according to docker docs:
FROM node:8 as build
WORKDIR /usr/src/app
COPY package.json yarn.lock ./
RUN yarn
COPY . ./
RUN REACT_APP_BACKEND_BASE_URL=http://localhost:8010 yarn build
FROM mhart/alpine-node:8
RUN yarn global add serve
WORKDIR /app
COPY —-from=build /usr/src/app/build .
#COPY ./build .
CMD serve -p 80 -s .
but I'm getting the following error
Step 8/9 : COPY —-from=build /usr/src/app .
COPY failed: stat /var/lib/docker/tmp/docker-builder527544225/—-from=build: no such file or directory
I also tried the index instead of the name: COPY —-from=0 but still same result.
if I skip first build, I manually kick the yarn build and I copy the build result into the single container
#COPY ./build .
it works fine...
