cloudimg .NET Web App Host on Ubuntu 24.04

cloudimg .NET Web App Host on Ubuntu 24.04 LTS

A complete host for ASP.NET Core web applications, not a bare runtime. The .NET 10 LTS SDK and the matching shared runtime are installed and pinned, a real application is already compiled and serving under Kestrel, and nginx sits in front as the single public entry point.

Licensing and provenance

.NET is installed exclusively from the Ubuntu 24.04 archive, from the main component, where Canonical builds it from the MIT licensed source. No Microsoft end user licence applies to anything in this image, and .NET receives security updates through the normal Ubuntu channel rather than a vendor feed. .NET 10 is an LTS release supported until November 2028.

What's Included

• .NET SDK 10.0.110 and the .NET and ASP.NET Core 10.0.10 runtimes, pinned and checksum verified at build time
• An ASP.NET Core application compiled on the image and running under Kestrel, bound to 127.0.0.1 only
• nginx as the sole public listener, enforcing HTTP Basic authentication on every path
• An administrator password generated uniquely on the first boot of every VM, with no default login
• A per VM data protection key ring, created on first boot and never baked into the image
• A dedicated data disk for your application, its source and its keys
• An unauthenticated health endpoint for load balancer probes

Use Cases

• Hosting ASP.NET Core web applications and web APIs
• Running .NET workloads behind an authenticating reverse proxy
• Building and running .NET applications on a single machine
