When attempting npm install in a Dockerfile, I thought disabling the colors would eliminate color codes in the Dockerhub build logs. However, that doesn't seem to be the case.
Can anyone point out where I might have gone wrong?
To see the details of the build, you can refer to the Dockerfile on Docker Hub:
Dockerfile:

RUN mkdir /src
WORKDIR /src
RUN cd /src
# Copy just the package.json file file as a cache step.
COPY package.json /src/package.json
# Disable progress so npm would install faster.
# Disable colors, because Dockerhub can't display them.
# Install NPM packages excluding the dev dependencies.
RUN npm set progress=false && npm set color=false && npm install --production
COPY . .
RUN npm run build
EXPOSE 8080
CMD ["npm", "run", "start"]
