Learn DevOps, SRE & AI engineering on real clusters, not slides.
Every episode comes with the lab behind it: the exact commands, the real output, and what broke. Plus interview prep written by a working senior platform engineer.
Episodes
Long-form episodes where everything on screen ran for real. Each one links to its lab.
SRE Mock Interview
A full SRE interview with a live production incident on a real Kubernetes cluster: fundamentals, CrashLoopBackOff and OOMKilled, a rollback that didn't fix it, Linux on-call, observability, system design for four nines and a blameless postmortem.
AI Engineer Roadmap 2026
The 7-stage roadmap from a working platform engineer: foundations, LLMs, RAG, evals, agents and tools, shipping to production, and security. Every stage built and run for real.
Platform Engineer Mock Interview
The deep platform interview: kubectl apply internals, scheduling and preemption, networking, Karpenter on real EKS, Argo CD drift, Terraform state, multi-tenancy and policy, a live Postgres failover, and designing a platform for 200 engineers.
Labs you can run tonight
Copy-paste setup, the real output from our run, and the explanation of what happened. Most run on a laptop with kind.
Kubernetes Incident Lab: Production Is Down
Break a real checkout service with a bad release, then debug it like an on-call SRE: CrashLoopBackOff, OOMKilled (exit 137), a rollback that doesn't fix it, a service selector trap, a capaci…
AI Engineer Lab: Local LLMs, RAG, Evals and a Safe Agent
Run open-source models locally with Ollama, see tokens and temperature for yourself, build a small RAG app over Kubernetes runbooks, write an eval that catches a retrieval failure, and build…
Platform Engineering Lab: Scheduling, GitOps, Terraform, Policy and Postgres
Everything from the platform engineer interview, on a 3-node kind cluster labelled as three zones: what kubectl apply really sends, topology spread, priority and preemption, Argo CD drift an…
Karpenter on EKS: From Pending Pods to a New Node in 30 Seconds
A real Amazon EKS cluster with Karpenter 1.15. Five pods that don't fit, a NodePool with a hard CPU limit, Karpenter picking one right-sized instance in about 30 seconds, and consolidation r…
Learning paths
Step-by-step routes through the episodes, labs and guides, in the right order.
DevOps → SRE
Learn to think like an SRE: SLOs and error budgets, debugging a real outage, and the questions SRE interviews actually ask.
DevOps → Platform Engineer
Go from running pipelines to building the platform: Kubernetes internals, GitOps, Terraform, Karpenter, multi-tenancy and databases.
DevOps → AI Engineer
Use what you already know about infrastructure to build AI features people can trust: local models, RAG, evals and safe agents.
