Not working in node:alpine Docker base image about mozjpeg-bin

[divick]

Here is the recipe for docker image based on node:10-15-alpine, which has node v10 and yarn already installed.

One can use alpine-3.9 image too but would need to add build steps to install node and yarn/npm.

FROM node:10.15-alpine                                                                            
                                                                                                  
RUN apk --no-cache add shadow \                                                                   
    gcc \                                                                                         
    musl-dev \                                                                                    
    autoconf \                                                                                    
    automake \                                                                                    
    make \

    nasm \                                                                                        
    tiff \

    file \

Want to extend what @divick wrote.
With the current image of node:alpine these dependencies allowed me to build mozjpeg within my drone-runner

- name: npm install
    image: node:alpine
    commands:
      - apk add autoconf automake libtool make tiff jpeg zlib zlib-dev pkgconf nasm file gcc musl-dev
      - npm install

@kachkaev I have been able to resolve this issue. On investigating I found that imagemin-mozjpeg installs mozjpeg-bin but in absence of autoconf, automake, libtool, make, gcc, musl-dev and nasm cannot build mozjpeg-bin from source and pulls in a GLIBC linked binary from github. Since alpine linux has musl-dev, the cjpeg cannot run without rebuilding/relinking with musl libc.

Just install the above packages with apk add and then do npm install and it should work.

As above, we need to install appropriate dependencies for mozjpeg to use it on any platform including alpine.

Great news @divick! Feel free to share the dockerfile recipe. I probably won’t change my setup for now, but people coming here from search will definitely be happy to see the solution!

Additionally you may need zlib-dev, pkgconf and file packages to be installed in alpine image.
