04 / CONTAINERS

Docker and Kubernetes, demystified.

Production-grade clusters without the conference-talk fantasy stack.

Outcomes

  • Deploys stop rolling back at 17:55 on a Friday.
  • Resource limits match real workloads, not copy-pasted YAML.
  • Secrets leave the environment variables.

A typical engagement

Single-node Docker estate rebuilt as a three-node K8s cluster, one ingress, one TLS cert.
