✅ Run PuppeteerSharp in Docker Container

I have an endpoint that creates PDFs using PuppeteerSharp. I work fine locally because it can automatically download Chromium. The opposite in the Docker Container, it tells me that no executable chromium found. Is there a way to pre download?

FROM mcr.microsoft.com/dotnet/sdk:8.0 as build
WORKDIR /App

COPY . ./

RUN dotnet restore
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/aspnet:8.0
WORKDIR /App
COPY --from=build /App/out .
ENTRYPOINT ["dotnet", "Vocabify.API.dll"]

FROM mcr.microsoft.com/dotnet/sdk:8.0 as build
WORKDIR /App

COPY . ./

RUN dotnet restore
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/aspnet:8.0
WORKDIR /App
COPY --from=build /App/out .
ENTRYPOINT ["dotnet", "Vocabify.API.dll"]

let's see if it works I've tried the way it installs on Linux

RUN apt-get update && apt-get install -y wget gnupg
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' | tee /etc/apt/sources.list.d/google-chrome.list
RUN apt-get update && apt-get install -y google-chrome-stable
RUN rm -rf /var/lib/apt/lists/*

ENV PUPPETEER_EXECUTABLE_PATH "/usr/bin/google-chrome-stable"

RUN apt-get update && apt-get install -y wget gnupg
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' | tee /etc/apt/sources.list.d/google-chrome.list
RUN apt-get update && apt-get install -y google-chrome-stable
RUN rm -rf /var/lib/apt/lists/*

ENV PUPPETEER_EXECUTABLE_PATH "/usr/bin/google-chrome-stable"

But if I look into the container there is nothing along this path, let me check if there any docker specific guides

I build it with docker compose and if there is error it shows it in console and process stops. That's why I'm not sure why it's not working for me, while in the guide it works. Now it gives me exception that it's searching chrome inside /App/Chrome/Linux-124.0.6367.60/chrome-linux64/chrome and can't find This configuration worked for me Dockerfile
