Docker security hardening involves enforcing non-root users, utilizing minimal base images, and restricting capabilities to minimize vulnerabilities. This Skill provides reference patterns and sample configurations to systematically apply these security measures across containerized applications.

Multi-stage builds optimize Docker images by separating the build and runtime environments, discarding unnecessary build dependencies. This approach reduces final image size and attack surface while ensuring only production-ready artifacts are included in the deployed container.

To maximize layer caching, structure Dockerfiles by ordering instructions from least to most frequently changing, placing dependency installation before source code copying. This Skill offers reference patterns to optimize cache hits and reduce build times.

Standardizing health probes and restart policies in Docker Compose ensures service reliability and automated recovery from failures. This Skill provides orchestration patterns for development and production environments to streamline health check implementation across multi-service architectures.

Yes, applying the deployment patterns, references, and sample configurations requires Docker installed locally or in a CI environment. The Skill provides documentation and patterns that must be validated by running a local test environment to ensure health checks and network isolation function correctly.

Auditing involves reviewing existing Dockerfiles and Docker Compose configurations against recommended patterns for multi-stage builds, non-root users, and minimal images. This Skill consolidates best practices to identify gaps and systematically adopt secure, efficient, and maintainable container configurations.
