Hello I'm working with my first docker project but having a problem reducing the image size.
FROM node:14.15.0-alpine
RUN mkdir /app
WORKDIR /app
COPY . .
# COPY ./medichis-kubernetes/config.json .
RUN npm install && npm run build
EXPOSE 7575
CMD [ "node", "./dist/src/bin/www.js" ]
The single stage docker image with this code is run okay but, the multi stage docker image with the following codes causes an error.
# Stage 1: Build Stage
FROM node:14.15.0-alpine AS BUILD_IMAGE
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
# Stage 2: Production Stage
FROM node:14.15.0-alpine
WORKDIR /app
COPY --from=BUILD_IMAGE /app/dist ./dist
COPY --from=BUILD_IMAGE /app/node_modules ./node_modules
COPY --from=BUILD_IMAGE /app/package*.json ./
COPY --from=BUILD_IMAGE /app/config.json ./
EXPOSE 7575
CMD [ "node", "./dist/src/bin/www.js" ]

- I checked the image is created right with a tag.
- I built npm project locally, and the directory is Root/dist/src/bin/www.js that is same as the one inside the dockerfile.
What do you think I can do more? Thank you in advance.
