Repro box is up. Probably run 'ldconfig /usr/local/lib' so that you can run command line programs like 'convert -list font' to check if ImageMagick can find fonts. You can bash into the container with: docker-compose exec repro sh Then install ImageMagick with configure something like: ./configure --with-quantum-depth=16 \ --with-magick-plus-plus=no \ --without-perl \ --disable-docs \ --with-jpeg=yes \ --with-png=yes \ --with-fontconfig=yes \ --with-webp=yes \ --with-urw-base35-font-dir=/usr/share/fonts/opentype/urw-base35 And so the long day wears on.
