Client‑Go is the official Go client library for Kubernetes, offering low‑level HTTP handling, local caching, and event‑driven List‑Watch mechanisms; the article explains its architecture, client types, cache components, code examples, and best practices for building production‑grade controllers and operators.
This article walks through extending the K8s Chat command‑line tool by adding an ‘analyze event’ command that gathers warning‑level events and pod logs, stores them in a map, and sends the information to a large‑language model via OpenAI’s API to receive actionable troubleshooting recommendations, while also suggesting further enhancements such as self‑healing and visualization.
This tutorial shows how to combine Kubernetes client‑go, the Cobra CLI framework, and OpenAI function calling in Go to create an interactive command‑line assistant that can generate YAML, deploy resources, query objects, and delete items in a Kubernetes cluster.
The article explains how to design and implement a sharded WorkQueue in Kubernetes' controller-runtime, enabling concurrent processing while guaranteeing that resources belonging to the same node are handled sequentially within a single goroutine, using hash-based partitioning and custom queue structures.
The article shows how adding Transform functions to client-go and controller-runtime informers trims metadata, cutting apiserver memory usage by up to 60% when watching hundreds of Secrets and ConfigMaps in large Kubernetes clusters.
This curriculum provides a comprehensive, step‑by‑step exploration of Kubernetes internals—including kubeadm core source, Go module management, cobra libraries, kubeadm init/join processes, client‑go components, code generators, custom resources, operators, and practical deployment automation—aimed at mastering cluster setup, configuration, and advanced development.
This article explains the internal workflow of the Kubernetes informer package in client-go, covering its architecture, key components such as Reflector, DeltaFIFO, and Indexer, and provides a step‑by‑step code example that demonstrates how informers are created, registered, started, and used to handle watch events efficiently.
This tutorial shows how to use the Go client-go library to create a command‑line tool that lists PersistentVolumeClaims, watches PVC events in a Kubernetes cluster, and triggers actions when total claimed storage exceeds a configurable threshold.
