Can't run Puppeteer Sharp in Docker

Description

I am not able to run Puppeteer Sharp in a Windows docker container. It gives an error while trying to launch chromium.

Complete minimal example reproducing the issue

            var options = new LaunchOptions
            {
                Headless = true
            };

            Console.WriteLine("Downloading chromium");
            await Downloader.CreateDefault().DownloadRevisionAsync(Downloader.DefaultRevision);

            Console.WriteLine("Navigating google");
            using (var browser = await Puppeteer.LaunchAsync(options, Downloader.DefaultRevision))
            using (var page = await browser.NewPageAsync())
            {
                await page.GoToAsync("http://www.google.com");

                Console.WriteLine("Generating PDF");
                await page.PdfAsync(Path.Combine(Directory.GetCurrentDirectory(), "google.pdf"));

                Console.WriteLine("Export completed");
                Console.ReadLine();
            }

Actual behavior:

Downloading chromium
Navigating google

For the record I was able to make it work just via:

RUN apt-get update && apt-get install -y xorg openbox libnss3 libasound2

(in my Dockerfile) and:

var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = true,
    Args = new string[] { "--no-sandbox" }
});

in my launch code.

This is what I used in my dockerfile for installing the dependencies for chrome/puppeteer:

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app

RUN apt-get update

RUN apt-get install -y wget unzip fontconfig locales gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget

and this is the code I used to warmup chrome:

public HeadlessChrome()
        {

            _options = new LaunchOptions
            {
                Headless = true,
                Args = new string[] { "--no-sandbox" }
            };
            DownloadChrome().ConfigureAwait(true).GetAwaiter().GetResult();
        }

        private async Task DownloadChrome()
        {
            BrowserFetcher browserFetcher = new BrowserFetcher();
            var folder = browserFetcher.DownloadsFolder;
            await browserFetcher.DownloadAsync(BrowserFetcher.DefaultRevision);

            if (System.Runtime.InteropServices.RuntimeInformation
                                   .IsOSPlatform(OSPlatform.Linux))
            {
                var path = Launcher.GetExecutablePath();
                Bash($"chmod 777 {path}");
            }
        }

        public void Bash(string cmd)
        {
            var escapedArgs = cmd.Replace("\"", "\\\"");

            var process = new Process()
            {
                StartInfo = new ProcessStartInfo
                {
                    FileName = "/bin/bash",
                    Arguments = $"-c \"{escapedArgs}\"",
                    RedirectStandardOutput = true,
                    UseShellExecute = false,
                    CreateNoWindow = true,
                }
            };
            process.Start();
            string result = process.StandardOutput.ReadToEnd();
            process.WaitForExit();
        }

The only “problem” I had so far is it didnt install some fonts for example calibri but i’m looking into that.
