When to Use Docker Advanced

Decision matrix per scegliere la tecnologia giusta

IDEAL USE CASES

Microservices orchestration where Docker advanced optimization excels in scaling containerized apps
CI/CD pipelines leveraging Docker advanced troubleshooting for zero-downtime deployments
Resource-constrained environments using Docker advanced best practices for 50% memory reduction

AVOID FOR

Single-container hobby projects - stick to basics avoiding Docker advanced complexity
Legacy monoliths where Docker advanced multi-stage builds add unnecessary overhead
Windows GUI apps - Docker advanced networking pitfalls dominate common queries

Core Concepts of Docker Advanced

Production-ready compilation flags and build commands

Optimization: Multi-stage Builds

Reduce image size by 70% using runtime-only layers. See multi-platform Docker builds examples below

⚠️ Common Error

COPY --from=builder /app /app fails

✓ Solution

Use /usr/src/app as source path

+70% size reduction

Troubleshooting: Container Networking

Advanced bridge vs overlay networks for swarm

+300% throughput

How to debug Docker containers

Runtime introspection with exec and logs

5x faster than rebuilds

Best Practices: Security Scanning

Trivy integration in CI

⚠️ Common Error

docker scan fails on multi-arch

✓ Solution

Use --platform flag

Docker advanced multi-platform builds

Buildx for ARM64/AMD64 cross-compilation
