Digest #188: Kubernetes Retires ingress-nginx, Netflix Scales Logging to Petabytes, and What Anthropic Really Spends on AWS
Plus: a 70TB data breach at Tata Motors, hands-on CI/CD and Postgres tutorials, and new tools like CronMaster, Wave, and Kratos.
Welcome to this week’s edition of the DevOps Bulletin!
Netflix showed how it handles petabytes of logs with ClickHouse, while Kubernetes announced the retirement of ingress-nginx, pushing teams toward Gateway API. A new report broke down how much Anthropic and Cursor really spend on AWS, and a major breach at Tata Motors exposed over 70 TB of customer data.
On the practical front: why certifications may not matter as much as you think, why /dev/null is technically “ACID,” and the surprising amount of math every SRE should know for reliability work.
Hands-on this week: building a CI/CD runner in Python, the best MCP servers for developer workflows, regression-testing PostgreSQL queries, running Docker from a web UI with Komodo, and securing self-hosted GitLab.
Tools of the week: CronMaster (cron job UI), ctop (real-time container metrics), Wave (terminal + AI + file previews), Gerbil (local LLM desktop app), and Kratos (identity management).
All this and more in this week’s DevOps Bulletin, don’t miss out!

📘 FinOps Tip of the Week
Most Kubernetes clusters quietly waste 30–50% of their compute budget because resource requests don’t match actual usage. Here’s your quick optimization checklist:
✅ Use the Vertical Pod Autoscaler (VPA) to analyze and adjust CPU/memory requests based on real metrics.
✅ Set resource limits to prevent runaway pods from eating cluster capacity.
✅ Run a weekly kubectl top pods --all-namespaces check or use tools like Goldilocks or Kubecost to spot idle resources.
✅ If you’re using managed services (EKS, GKE, AKS), pick spot or preemptible nodes for non-critical workloads.

Projects of the week
CronMaster is a self-hosted tool that lets you view, create, and manage cron jobs through a simple interface with real-time updates and optional logging.
ctop provides a concise and condensed overview of real-time metrics for multiple containers.
Wave is a terminal that combines traditional terminal features with graphical capabilities like file previews, web browsing, and AI assistance.
Gerbil is a desktop app that helps you run local LLMs through a clean interface powered by KoboldCpp with support for text and image generation.
Kratos is an API-driven identity system that handles login, registration, recovery, MFA, and profile management for cloud-native apps.
