Most likely "The platform may be missing native dependencies (libjpeg62, etc)". Alpine is very lightweight so it requires a lot of dependencies to be installed. See the other issues here for guidance.
I tried to add such packages RUN apk update && \ apk add --no-cache \ bash \ icu-libs \ krb5-libs \ libgcc \ libintl \ libssl1.1 \ libstdc++ \ zlib \ libstdc++ \ libx11 \ libxrender \ libxext \ libssl1.1 \ libjpeg \ gcompat \ ca-certificates \ fontconfig \ freetype \ ttf-dejavu \ ttf-droid \ ttf-freefont \ ttf-liberation && \ apk add --no-cache libgdiplus --repository https://dl-3.alpinelinux.org/alpine/edge/testing/ && \ ln -s /usr/lib/libjpeg.so.8 /usr/lib/libjpeg.so.62
I can't tell exactly what you need to do, but I know it's a lot harder with the Alpine distribution. Do you have to use that, or could you use one that is known to work? Also you can try to get the wkhtmltopdf
native command-line tool to run first, the error you're getting is not actually due to this package, but it's an issue when loading the native library.
There is a sample here: https://github.com/HakanL/WkHtmlToPdf-DotNet/tree/master/src/TestConsoleAppDockerAlpine
Unable to load native library. The platform may be missing native dependencies (libjpeg62, etc). Or the current platform is not supported.
