Docker β€” Build evidence and production operations

Assess multi-stage and multi-platform content, cache trust, incidents, supply chains, and recovery.

What you will learn

  • Control build inputs and verify artifact and platform identity.
  • Correlate operational evidence and design rootless, supply-chain, and restore policies.

  1. Multi-stage builds and reproducible release inputs

    Separate toolchains from runtime artifacts and distinguish a small image from a reproducible build.

    Start learning

  2. Cache design and measured build performance

    Reuse valid work while preserving correct dependency invalidation and trust boundaries.

  3. Multi-platform images and cross-compilation

    Distinguish an image index, a platform-specific manifest, a builder architecture, and a runtime architecture.

    Start learning

  4. Correlated observability and incident diagnosis

    Connect deployment identity, process state, logs, metrics, and consumer symptoms before changing a running system.

    Start learning

  5. Rootless operation and image supply-chain evidence

    Reduce daemon authority while verifying where release content came from and what supporting metadata actually proves.

    Start learning

  6. Production operations, persistent data, and recovery

    Create an operational contract covering ownership, recovery objectives, upgrades, and failure evidence rather than relying on container persistence alone.
