This guide shows how to replace the error‑prone manual TLS workflow in Kubernetes by integrating cert‑manager, External DNS and the NGINX Ingress Controller to automatically obtain, validate and renew Let’s Encrypt certificates, reducing cost and operational overhead.
The article explains why traditional branch‑based deployments cause service outages, introduces Header routing as a logical, zero‑downtime gray‑release solution, details its core principles, benefits, implementation with Nginx Ingress, and provides practical code examples for seamless version switching.
This guide explains how NGINX‑Ingress works, outlines key considerations for running multiple instances, and provides step‑by‑step instructions—including helm installation, custom controller parameters, admission webhook scoping, and verification screenshots—to reliably deploy and manage several NGINX‑Ingress controllers in a Kubernetes cluster.
This guide explains why routing traffic through an Nginx Ingress controller can halve Kubernetes service QPS and provides step‑by‑step instructions—including switching to IPVS, tuning kernel and file‑descriptor limits, and configuring keep‑alive settings—to restore and even exceed the original performance.
The article walks through diagnosing why a second Kubernetes cluster ignored the upload‑size setting, shows how to inspect the nginx‑ingress‑controller deployment, identify the --configmap argument, and fix the issue by updating the referenced ConfigMap name to nginx‑configuration.
This article provides a comprehensive guide to Nginx Ingress on Tencent Cloud TKE, covering its fundamentals, three deployment architectures, selection criteria, internal and external load‑balancer configurations, bandwidth considerations, Ingress creation, and monitoring with Prometheus.
