Optimize Docker images by using multi-stage builds, ordering Dockerfile layers from least to most frequently changing, and configuring .dockerignore to exclude unnecessary build context files.

Secure Docker runtime by configuring non-root users, setting resource limits, managing capabilities, implementing health checks, and establishing proper restart policies and secrets management for production deployments.

Multi-stage builds use multiple FROM statements in a Dockerfile to copy only necessary artifacts from builder stages to a minimal final image, reducing size and excluding build dependencies.

Docker Compose supports production deployments by defining multi-container application architectures, configuring logging, managing secrets, and applying resource constraints and restart policies.

Manage Docker secrets using built-in secret management tools and monitor containers by implementing structured logging, backup strategies, and health checks across Linux, macOS, and Windows platforms.
