RUN npm ci --only=production causes exporting layers to fail

So I started using img to build dockerfiles from within a docker container. Tried with 0.5.7 but it would not let me run build like some other issues I found that were having problems with 0.5.7 like #250 so I reverted to 0.5.6 and ran my original container (external) with the --privileged flag.

Problem

My dockerfile of the internal container looks like :-

FROM node:10

LABEL maintainer="Nisarg Tuli"

# Create app directory
WORKDIR /usr/src/app

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./

RUN npm install
# If you are building your code for production
RUN npm ci --only=production

# Bundle app source
COPY . .

EXPOSE 8081

ENV NEUTRINOS_APP_ENV=dev

CMD ["node", "./build/index.js"]

Problem Stack Trace

This caused the following error for the docker file :-

Solution

Removing just RUN npm ci --only=production from my internal dockerfile fixed the issue and I was able to build. This happens with other npm commands like npm prune --production Seems to be an issue with the --production flag.

Just dropping this here for anyone else. Hope this helps someone. Spent a lot of sleepless nights hunting this problem down.

Excellent work everyone involved in this project Take care guys and Have a nice day!!
