Containers and orchestration

Package and run services with Docker and Kubernetes.

📖 Key ideas

  1. Each service ships as a container image.
  2. Kubernetes schedules, scales and heals containers.
  3. Use Deployments, Services and Ingress for each microservice.
  4. Service meshes (Istio, Linkerd) add mTLS, retries and observability.
  5. Helm charts package service deployments.
💡 Real-life example: Containers are lunchboxes for each service; Kubernetes is the canteen manager serving them at scale.
