Using imagemin-mozjpeg with Docker throws this error "spawn Unknown system error -8"

On my macOS I don't seem to have any issue, but when using Docker I get this output:

I cleaned cache, ran npm i again but nothing helps. Earlier, I fixed this issue: mozjpeg/vendor/cjpeg` binary doesn't seem to work correctly—https://github.com/imagemin/imagemin-mozjpeg/issues/28

I did some research yet couldn't find someone that faces the exact problem.

Solution

  • After hours of research and experimenting with different settings, I managed to resolve mozjpeg errors when using Linux/Docker. The issue is particularly when using alpine image.

    My updated Dockerfile:

    FROM node:12-buster-slim

RUN npm i npm@latest -g

WORKDIR /usr/src

COPY ./app/package*.json ./

RUN apt-get update && apt-get install -y --no-install-recommends \
    autoconf \
    automake \
    g++ \
    libpng-dev \
    make\
    nasm \
    -y wget \
    && wget -q -O /tmp/libpng12.deb http://mirrors.kernel.org/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1_amd64.deb \
    && dpkg -i /tmp/libpng12.deb \
    && rm /tmp/libpng12.deb \
    && npm install --no-optional && npm cache clean --force \
    npm install -g gulp \
    && npm install gulp

ENV PATH /usr/src/node_modules/.bin/:$PATH

WORKDIR /usr/src/app

COPY . .

    These settings might save you hours of frustration. BTW Node's alpine image is NOT recommended because of long build time, even though it's small image size.

    Happy coding!
