如何让 Puppeteer-Sharp 在 AWS Elastic Beanstalk 运行 Docker (.NET Core 6) 上工作？

Question

我正在寻找有关如何在 AWS Elastic Beanstalk 实例运行 Docker (.NET Core 6) 上获取 PuppeteerSharp 运行的最新示例。那里有相当多的文章要么过时，要么文档不足，要么两者兼而有之。我尝试在我的 Docker 文件中安装 Chrome 依赖项，但是，我无法获取它运行.

有人有使用 AWS + .NET Core 6 + Docker + Puppeteer 的工作示例吗？

这是我当前的Docker文件：

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY . ./
ARG VERSION_SUFFIX=dev
ENV VERSION_SUFFIX=v$VERSION_SUFFIX
RUN dotnet restore Book/*.csproj
RUN dotnet publish Book/*.csproj -c Release -o out /p:VersionSuffix=$VERSION_SUFFIX

# Build runtime image
FROM mcr.microsoft.com/dotnet/aspnet:6.0

WORKDIR /app
COPY --from=build-env /app/out .
EXPOSE 80
EXPOSE 443
ENTRYPOINT ["dotnet", "Book.dll"]

RUN  apt-get update \
     && apt-get install -y wget gnupg ca-certificates \
     && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \
     && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' \
     && apt-get update \
     # We install Chrome to get all the OS level dependencies, but Chrome itself
     # is not actually used as it's packaged in the node puppeteer library.
     # Alternatively, we could could include the entire dep list ourselves
     # (https://github.com/puppeteer/puppeteer/blob/master/docs/troubleshooting.md#chrome-headless-doesnt-launch-on-unix)
     # but that seems too easy to get out of date.
     && apt-get install -y google-chrome-stable \
     && rm -rf /var/lib/apt/lists/* \
     && wget --quiet https://raw.githubusercontent.com/vishnubob/wait-for-it/master/wait-for-it.sh -O /usr/sbin/wait-for-it.sh \
     && chmod +x /usr/sbin/wait-for-it.sh

代码：

using var browserFetcher = new BrowserFetcher();
await browserFetcher.DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = true, Args = new[] {"--no-sandbox"}
});
await using var page = await browser.NewPageAsync();

异常：

An unhandled exception was thrown by the application.","Exception":"PuppeteerSharp.ProcessException: Failed to launch browser! /app/.local-chromium/Linux-884014/chrome-linux/chrome: error while loading shared libraries: libgobject-2.0.so.0: cannot open shared object file: No such file or directory     at PuppeteerSharp.States.ChromiumStartingState.StartCoreAsync(LauncherBase p) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\States\ChromiumStartingState.cs:line 83    at PuppeteerSharp.States.ChromiumStartingState.StartCoreAsync(LauncherBase p) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\States\ChromiumStartingState.cs:line 89    at PuppeteerSharp.Launcher.LaunchAsync(LaunchOptions options) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\Launcher.cs:line 68    at PuppeteerSharp.Launcher.LaunchAsync(LaunchOptions options) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\Launcher.cs:line 91

对于仍然遇到此问题的任何人，answer by jamie-tillman 这个 github 问题为我解决了：

可执行文件的路径由 Puppeteer 自动检测。但是，我仍然必须禁用沙盒模式，如下面的代码片段所示：

var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = true,
    Args = new [] {
      "--disable-gpu",
      "--disable-dev-shm-usage",
      "--disable-setuid-sandbox",
      "--no-sandbox"}
});
