Harbiden öyle. Eskiden fullstack fr*ntend ve backend birlikte bilmekti. Şu an fullstackin sağdakinden fazlası var eksiği yok.

Reduced Docker image size from 2.1GB to 180MB. Deployments 8x faster. The original Dockerfile: - Started with ubuntu:latest - Installed everything via apt - Included dev dependencies - Copied entire project directory - Left build artifacts - No layer optimization The problems: - Pull time: 6-8 minutes - Registry storage costs high - Deployment took forever - Security scan found 47 vulnerabilities - Most from unnecessary packages What we optimized: 1. Base image - ubuntu:latest (2.1GB) → alpine:latest (5MB) 2. Dependencies - Removed dev dependencies - Multi-stage build - Only production packages 3. Layer caching - Copied requirements first - Installed dependencies - Then copied source code - Leveraged Docker layer cache 4. .dockerignore - Excluded .git, tests, docs - Removed 800MB of files The new image: 180MB The impact: - Pull time: 6min → 45sec - Build time: 8min → 2min - Deploy frequency: 2x per day → 15x per day - Registry costs: $340/month → $60/month - Security vulnerabilities: 47 → 3 - Kubernetes pod startup: 90sec → 12sec Every MB in your image costs time and money. Optimize Docker images like you optimize code.
