Production Kubernetes Across Environments
Bridge the gap between basic container concepts and running reliable clusters across Google Cloud, self-hosted GitHub Actions runners, bare metal, and Talos Linux.
Like Duolingo, but for Production Kubernetes Across Environments. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Managed Kubernetes on Google Cloud, Scalable CI/CD with Kubernetes Runners, Kubernetes on Bare Metal and On-Premises, and Modern Immutable Infrastructure with Talos Linux. It assumes you already know the basics.

Key ideas in Production Kubernetes Across Environments
- Autopilot manages nodes automatically and restricts SSH, hostPath, and privileged DaemonSets.
- Standard mode grants full access to node pools, custom machine types, and underlying VM config.
- Autopilot bills per requested Pod resource, while Standard bills for provisioned worker VMs.
- Workload Identity maps a Kubernetes ServiceAccount to an IAM ServiceAccount in Google Cloud.
- The GKE metadata server intercepts Pod token requests to fetch short-lived OAuth tokens.
- Annotating the Kubernetes ServiceAccount tells GKE which IAM identity to impersonate.
- VPC-native clusters allocate secondary subnet IP ranges directly to Pods via alias IPs.
- Routes-based clusters rely on static VPC routing tables that hit network scale limits.
- Alias IPs eliminate the performance overhead of overlay packet encapsulation networks.
- Node Auto-Provisioning inspects unscheduled Pod resource requests to create new node pools on the fly.
- Standard Cluster Autoscaler can only add or remove instances in pre-existing node pools.
- Node Auto-Provisioning automatically selects the optimal machine family and hardware accelerator.
- Maintenance windows restrict automated GKE control-plane and node upgrades to defined hours.
- PodDisruptionBudgets block GKE node draining if eviction would drop replicas below a threshold.
- Blue-green upgrade strategy creates a new node pool and drains workloads before deleting old nodes.
- GKE Ingress provisions external Google Cloud Load Balancers outside the cluster.

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Production Kubernetes Across Environments the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
