Docker

Containerization for consistent deployments, portable environments, and reproducible builds from development to production.

Docker — engineering delivery and architecture

Docker packages applications with their dependencies into immutable images — eliminating “works on my machine” drift between developers, CI, and production. Teams ship faster because environments are reproducible; operations teams roll back by redeploying a known image tag. We use multi-stage builds, minimal base images, and registry scanning so containers stay small, secure, and fast to pull. Docker is the foundation under Kubernetes, ECS, and many CI pipelines — standardizing how NarixSolutions delivers backend APIs, workers, and full-stack products.

Docker — implementation and platform context

Security & vulnerability posture

Read-only root filesystems where viable, no secrets baked into images, regular base-image patches, and network policies at the orchestration layer. Developers do not run production images locally with production credentials. CI signs or attest images when client compliance requires it.

Delivery focus areas

How we stitch this capability into PWAs, public websites, admin consoles, integrations, and long-term roadmaps.

Containerization & build consistency

Deterministic builds that encode runtime, system libraries, and application code in versioned artifacts.

  • Multi-stage Dockerfile optimization
  • Pinned dependency locks in images
  • Local compose stacks mirroring prod services
  • Image tagging aligned to Git releases
Deployment portability

Same image promoted across staging and production — reducing configuration surprises at go-live.

  • Registry promotion workflows
  • Environment-specific config via secrets, not image rebuilds
  • Healthcheck and graceful shutdown hooks
  • Resource limits and ulimits set per service
Supply chain hygiene

Vulnerability scanning and base-image update cadence treated as operational requirements.

  • SBOM generation where required
  • Non-root container users by default
  • Distroless or slim bases when appropriate
  • Blocked critical CVEs in CI gates
Integration with orchestration

Images ready for Kubernetes, ECS, or Nomad with observability agents and sidecars planned upfront.

  • Structured logging to stdout
  • Metrics endpoints for scraping
  • Init containers for migrations
  • Secrets mounted via platform primitives
