The task
Task
One Deployment contains multiple Alpine-based containers.
Requirements
- Identify which Alpine image contains
libcrypto3 - Remove the container using that image from the Deployment
multi-alpine - Generate an SPDX document:
bom generate --image alpine:3.19.1 --output /root/alpine.spdx
Verify that the SPDX file was created.
What this tests
Scan images for vulnerabilities, harden Dockerfiles, generate SBOMs, and enforce image policy. On the CKS exam, Supply Chain Security tasks are graded purely on what you build in the cluster — not multiple choice — so the only way to get faster is to do them on a real cluster against a clock.
Practice it for real
prepium.sh drops you into your own isolated Kubernetes cluster in the browser — no install, no credit card. You solve the task in a real terminal, hit validate, and a programmatic checker scores exactly what you got right and wrong (with partial credit). The canonical solution unlocks after you attempt it, so you learn the fast, exam-ready way to do it.
