- Multi-stage builds help keep production Docker images small by separating build and runtime stages.
- BuildKit cache mounts can significantly speed up npm installations by reusing cached artifacts.
- Use RUN --mount=type=secret to inject secrets during builds without persisting them in the final image.
- Docker Compose profiles allow managing different environments (dev, staging, prod) within a single file.
- docker buildx bake simplifies building multi-architecture Docker images (e.g., amd64 and arm64).
- Healthchecks and dependency conditions in Docker Compose prevent race conditions during service startups.
- docker scout cves provides quick feedback on vulnerabilities in your Docker images.
- Enhance container security with flags like --init, --cap-drop, and tmpfs for production environments.
- Debug containers locally using docker run --network container:<id> to share network namespaces.
- Monitor container events in real-time with docker events to detect unhealthy workloads.
