Serve a Static Website as a Unikernel
Unikernels are specialized, single-purpose operating systems that package your application with only the minimal OS components it needs to run. Think of them as extremely lightweight VMs that boot in milliseconds and use a fraction of traditional server resources.
Rump Kernels take a unique approach: they let you extract specific drivers and components from existing operating systems (like NetBSD) and run them in userspace or as unikernels. This means you can use proven, mature OS components without the overhead of a full operating system. Your application gets direct access to high-performance networking, file systems, and other kernel services while maintaining strong isolation.
The result is applications that start faster, use less memory, have smaller attack surfaces, and can be deployed more efficiently than traditional containerized or VM-based approaches.
You'll learn how to use the Rumprun toolchain to build a unikernel that hosts your static website served by Nginx. This tutorial focuses on giving application and web developers practical steps to get running with Rump Kernel-based unikernels.
This assumes you're on a GNU/Linux or BSD system and familiar with command line basics.
