Why this decision matters

Container Artifact Trust Chain is focused practice for container artifact trust. It explains why each answer is safe, risky, or production-ready.

Build, attest, and promote one minimal immutable container artifact.

Learning objectives

  • Bind build and security evidence to one immutable digest.
  • Reduce runtime privileges and build context.
  • Promote verified artifacts without rebuilding.

How to play

  1. Inspect the evidence for each scenario.
  2. Choose or order the defensible actions.
  3. Review the explanation before continuing.
