aspnet:6.0-alpine docker image problem #88

Closed stefanodesimone closed 1 year ago

stefanodesimone commented 1 year ago

Hi all, I'm using visual studio pro 2022, in my docker file i use: FROM mcr.microsoft.com/dotnet/aspnet:6.0-alpine AS base Install:

  1. libgdiplus
  2. freetype-dev
  3. libpng-dev
  4. jpeg-dev
  5. libjpeg-turbo
  6. libjpeg-turbo-dev
  7. libc-dev
  8. libx11-dev

When i try to create a pdf file an error occur: AggregateException: One or more errors occurred. (Unable to load native library. The platform may be missing native dependencies (libjpeg62, etc). Or the current platform is not supported.)

Can anyone help me? Thx Stefano

The Alpine image is very bare-bones and requires quite a bit of dependencies. A good start is to look at what is in the sample https://github.com/HakanL/WkHtmlToPdf-DotNet/blob/master/src/TestConsoleAppDocker/Dockerfile. And also look at this issue that has a link to a potential solution. Once you figured out the solution feel free to post a PR with an Alpine docker example.

I've added a sample now that uses Alpine, it's quite different from the other distribution (very skinny), so you may run into issues with images, etc (basically I only tested that it could generate the simple text-only PDF). I think it would be better to use the larger base distribution. https://github.com/HakanL/WkHtmlToPdf-DotNet/tree/master/src/TestConsoleAppDockerAlpine
