Help to build a docker image for net core apps

[fjsosa]

Hi, I was trying to build a docker image based in this one to run a dotnet web app and I succesfully failed!. My question is: Is it possible to build an docker image that have preinstalled wkhtmltopdf?, or at least all the libraries required by wkhtmltopdf. My idea is to take that as base and add the net runtime an my binaries. Any help is welcomed! Thank you so much in advance.

Hi @fjsosa

Please try with this sample as a starting point:

FROM surnet/alpine-wkhtmltopdf:3.19.0-0.12.6-full as wkhtmltopdf
FROM mcr.microsoft.com/dotnet/aspnet:7.0.17-alpine3.19

# Install dependencies for wkhtmltopdf
RUN apk add --no-cache \
    libstdc++ \
    libx11 \
    libxrender \
    libxext \
    libssl3 \
    ca-certificates \
    fontconfig \
    freetype \
    ttf-dejavu \
    ttf-droid \
    ttf-freefont \
    ttf-liberation \
    # more fonts
  && apk add --no-cache --virtual .build-deps \
    msttcorefonts-installer \
  # Install microsoft fonts
  && update-ms-fonts \
  && fc-cache -f \
  # Clean up when done
  && rm -rf /tmp/* \
  && apk del .build-deps

# Copy wkhtmltopdf files from docker-wkhtmltopdf image
COPY --from=wkhtmltopdf /bin/wkhtmltopdf /bin/wkhtmltopdf
COPY --from=wkhtmltopdf /bin/wkhtmltoimage /bin/wkhtmltoimage
COPY --from=wkhtmltopdf /bin/libwkhtmltox* /bin/
