anonymouz/dotnet-chromium-base repository overview

⁠🐳 .NET 8 + Chromium Base Image

A production-ready, pre-configured base image combining the official .NET 8 ASP.NET runtime with headless Chromium.

Built specifically for .NET applications that rely on PuppeteerSharp, Playwright, or Selenium to generate PDFs, take screenshots, or scrape web pages inside Docker containers.

⁠Why use this image?

1. Faster Application Builds: No need to run apt-get install chromium during your main app build. Your CI/CD pipelines will be significantly faster.
2. Stability & Reliability: Debian repositories remove older Chromium packages when security updates are released, which can break your Dockerfile. This image locks the dependencies and acts as a safe, immutable layer.
3. Automated Testing: Every build of this image is automatically tested via GitHub Actions. It is only pushed to Docker Hub if Chromium successfully launches and generates a valid PDF.

⁠What's inside?

• mcr.microsoft.com/dotnet/aspnet:8.0 (Debian-based)
• chromium & chromium-common
• Essential system libraries: libicu72, librdkafka1, libexif12, udev, tzdata, curl, ca-certificates
• Pre-configured environment variables:
  • CHROMIUM_EXECUTABLE=/usr/bin/chromium
  • DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=false

⁠Updates

This image is automatically rebuilt and tested nightly to pull in the latest OS security patches and Chromium updates.
