To optimize a Dockerfile for security and efficiency, use multi-stage builds, select minimal base images, maintain proper layer hygiene, and configure non-root users to reduce attack surface and cache redundant steps.

Best practices for Docker Compose secrets management involve using dedicated secrets definitions rather than environment variables, alongside configured resource limits and healthchecks to secure multi-service setups.

Reviewing a Dockerfile for security involves checking base image selection, verifying non-root user implementation, analyzing layer hygiene, and ensuring proper secret management to eliminate vulnerabilities during container builds.

Yes, Docker Compose supports configuring healthchecks and resource limits for multi-service setups, allowing you to define networking rules and manage secrets to ensure maintainable and stable container orchestration.

The best way to improve Dockerfile build cache performance is ordering instructions from least to most frequently changing, utilizing multi-stage builds to isolate dependencies, and maintaining strict layer hygiene.

Docker image builds accumulate excessive layers and slow performance when instructions are unoptimized; combining commands, applying multi-stage builds, and enforcing layer hygiene resolves these inefficiencies.
