Docker

Reproducible environments and deployments with containers.

Docker is the de‑facto standard for containerised applications.
It lets you run software with all dependencies in isolated containers — portable, lightweight and reproducible.


Why Docker?

  • Portability: “Works on my machine” becomes a thing of the past.
  • Scalability: Easily duplicate and orchestrate containers.
  • Isolation: Clean separation of apps and services.
  • DevOps‑friendly: Pairs perfectly with CI/CD pipelines.

Typical use cases:

  • Local development environments
  • CI/CD builds & tests
  • Production for microservices
  • Infrastructure for headless apps & APIs

Services with Docker

  • Setup & configuration: Write Dockerfiles and Compose stacks.
  • Dev environments: Consistent setups for teams.
  • Production deployments: Optimised images for small size & high security.
  • Orchestration: Prepare for Kubernetes, Docker Swarm or others.

Example projects

  • Shopware 6 in Docker: Complete setup with DB, cache, queue workers.
  • Laravel environment: Multi-service stack with MySQL, Redis, Horizon.
  • CI/CD pipelines: Automated builds, tests and deployments in containers.

Best practices & security

  • Multi-stage builds, slim images and regular security scans
  • Secrets management via Docker Secrets, Vault or Kubernetes secrets
  • Resource limits, health checks and automatic restarts
  • Logging and monitoring integrations (ELK, Loki, Prometheus)

Orchestration & operations

  • Running on Kubernetes, k3s, Docker Swarm or ECS
  • Blue/green deployments, canary releases and rolling updates
  • Service mesh integration (Istio, Linkerd) for complex architectures
  • Documentation and training for DevOps teams

Conclusion

With Docker you get fast, scalable and secure environments — from development to production.
