Umbraco on Ubuntu 24.04 LTS by cloudimg
by cloudimg
ASP.NET Core CMS for editors and developers, with backoffice, .NET 10 and embedded SQLite.
Umbraco is a flexible, friendly open source content management system built on ASP.NET Core and .NET. It gives content editors a clean, modern backoffice for building pages, document types, templates and media, and gives developers a full Model View Controller and API surface for building sites and applications. This image is built and maintained by cloudimg on a hardened, fully patched Ubuntu 24.04 LTS base, running Umbraco 17.5.3 on the .NET 10 runtime under Kestrel behind nginx, with an embedded SQLite database so the appliance is complete and useful on its own with no separate database server.
A unique administrator account is created on the first boot of every VM using a per VM secret, and the login is written to a root only file. Umbraco ships no default login, and the cloudimg image goes further: the captured image contains no database at all, and no known or blank credential authenticates. The backoffice is served over HTTPS with a per VM self signed certificate because its modern login uses browser cryptography that only works in a secure context. Sign in at /umbraco to build pages, document types, templates and media, then publish your site.
The SQLite database, the media library and the ASP.NET Core DataProtection keyring all live on a single dedicated managed data disk, so your content stays off the operating system disk and rides with the VM, and backoffice sign in survives service restarts. Kestrel is bound to 127.0.0.1 only and is never exposed to the network; nginx is the only public listener, serving the site on port 80 and the backoffice on port 443. An unauthenticated /healthz endpoint is provided for load balancer probes. For production, replace the self signed certificate with your own domain certificate, or move to SQL Server for larger sites.
