Live Coding with Containers
summary
Live demo builds an Amazon ECS cluster, pushes an ancient Ubuntu image to Amazon ECR image scanning and immediately finds 4 high, 82 medium, 94 low and 34 informational CVEs. A small Lambda wired via EventBridge parses scan JSON and logs alerts, proving automatic reaction works. An Auto Scaling group mixes On‑Demand and Spot with per‑instance weighting and a Capacity Provider triggers ECS cluster auto scaling from 4 to ~14 instances to run six tasks. A Fargate service uses a Fargate Spot and On‑Demand split (1:4 weight) and launches the expected mix of tasks.
