Design a small subsystem that relies on Artifact Promotion (Build Once)
Answers use simple, clear English.
Quick interview answer
Sketch components, data flow, failure modes, and metrics around Artifact Promotion (Build Once). Example shape: CI pushes ghcr.io/app:sha-abc; staging and prod both pull sha-abc.
Detailed answer
Mini design using Artifact Promotion (Build Once): • Components: API edge, worker/queue, store, and observability. • Data flow: request → Artifact Promotion (Build Once)-related path → response/async side effects. • Failure modes: timeouts, overload, partial dependency loss. • Metrics: latency, errors, saturation for the Artifact Promotion (Build Once) path. Guardrails: Pin by digest; SBOM; sign images (cosign). Parent context: At Junior depth: start with the problem, then mechanism, then a short example. Build a versioned image/package once in CI; promote the same digest through staging→prod.
Full explanation
Interviewers want a crisp architecture story anchored on Artifact Promotion (Build Once), not a buzzword list. Build a versioned image/package once in CI; promote the same digest through staging→prod. Never rebuild for prod with different flags.
