Docker

Docker standardizes application delivery by packaging software into portable OCI containers, utilizing BuildKit multi-stage builds and vulnerability scanning for secure supply chains.

When to Use

• Application Containerization: Packaging code, runtime, system libraries, and settings into portable, reproducible container images.
• Multi-Stage Build Optimization: Creating ultra-small, secure production container images stripped of compilers and build tooling.
• Local Microservice Development: Orchestrating multi-container environments (app, database, cache) with Docker Compose.
• Standardized CI/CD Artifacts: Building OCI-compliant images deployed to Kubernetes, ECS, or serverless container runtimes.

Quick Start
