Building a Self-Updating Kubernetes Resource Crawler: Discovery API and Dynamic Client

Sun, 26 Jul 2026 09:00:00 -0500

Ask most engineers to export everything in a namespace and they reach for kubectl get all -o yaml. It feels comprehensive. It is not. The all category is a hardcoded shortlist inside kubectl, and it silently omits ConfigMaps, Secrets, PersistentVolumeClaims, Ingresses, NetworkPolicies, ServiceAccounts, RBAC bindings, and every Custom Resource an operator ever installed. Anything worth auditing is exactly the set all leaves out.

The correct approach is to ask the cluster what it can serve, then walk that list. The Kubernetes Discovery API enumerates every API group and resource the apiserver currently knows about, and the dynamic client lets you list any of them without compiling a single Go type. Composed together, they form a resource crawler that adapts to new CRDs the moment they are installed, with no code changes. A recent open source tool, k8s-ns-dump-dynamic, demonstrates the core loop in about 165 lines of Go and is a clean minimal example. This post builds that same crawler, then hardens it against the five ways the naive version fails in production: partial discovery, unbounded lists, swallowed permission errors, output that will not reapply, and client-side throttling.

Balancing Consistency and Flexibility in Multi-Environment Go Applications with Kubernetes

Tue, 09 Jun 2026 09:00:00 -0500

Introduction

When scaling Kubernetes-based Go applications across multiple environments—from development and staging to production and across multiple cloud providers—teams face a critical balancing act. How do you maintain consistent behavior and configurations while still allowing the necessary flexibility for each environment’s unique requirements? This challenge is especially relevant for Go microservices, where the language’s efficiency and containers’ portability create powerful but complex deployment scenarios.

In this guide, we’ll explore practical strategies for implementing a multi-environment Kubernetes architecture that strikes the right balance between standardization and adaptability for Go applications. We’ll provide concrete examples using real-world tools and practices that you can immediately apply to your own projects.
