Why does double 'COPY' in dockerfile give error
For some reason when im building my dockerfile i get this error:
"Step 9/11 : COPY --from=builder ./usr/src/app/dist /usr/app/dist
failed to copy files: lstat
/var/lib/docker/overlay2/d16c06f4e33e70fea8e03cfe566fe72a763bd1949b67b64603937758fdf7fe1f/merged/usr/app/dist:
not a directory"
However if i comment out one of the 'COPY' it works fine (Doesnt matter which one)
What exactly is going wrong here?
My dockerfile is as following:
FROM node:latest as builder
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build:ssr
FROM node:latest
COPY --from=builder /usr/src/app/package.json /usr/app
COPY --from=builder /usr/src/app/dist /usr/app/dist
WORKDIR /usr/app
CMD [ "npm", "run", "serve:ssr" ]
docker dockerfile

After the first copy /usr/app is a JSON file, not a directory. You can't create files inside a regular file, so you get the error "not a directory" when you try to create /usr/app/dist.

Problem is causing by this line:
COPY --from=builder /usr/src/app/package.json /usr/app
Here, you are copying /usr/src/app/package.json into /usr directory and naming package.json as app.
Specify that app is not file name. It's a directory. Use following
COPY --from=builder /usr/src/app/package.json /usr/app/
