§ Overview

About this video

What You'll Learn

  1. Use HTTP probes to discover runtime files inside a container image.
  2. Drive Slim Toolkit with exec probes for command-line applications.
  3. Shrink unoptimized Astro and NGINX images without breaking functionality.

Slim Toolkit probes a running container with HTTP or exec probes to learn which files the workload actually uses, then rebuilds a minimal image. Demos shrink NGINX from 33MB to 12MB, a Rust dog image from 97MB to under 10MB, and an unoptimised Astro build from 1.4GB to 100MB.
