Browse Topics

Detailed subtopics, terminologies, and technical guides. Dive straight into specific lessons and workflows mapped inside each concept.

All Topics

Configuring Ingress Controllers with NGINX for Production Traffic

Configure NGINX Ingress Controllers on Kubernetes to route production HTTP and HTTPS traffic with SSL termination, path routing, and rate limiting.

Explore

Configuring Kubernetes Resource Requests, Limits, and QoS Classes

Learn how to correctly set CPU and memory requests and limits on Kubernetes pods to prevent OOMKills, CPU throttling, and noisy neighbour problems in production.

Explore

Configuring Persistent Volumes and Storage Classes in Kubernetes

Configure PersistentVolumes, PersistentVolumeClaims, and StorageClasses in Kubernetes to provide durable storage for stateful workloads in production.

Explore

Configuring Pod Disruption Budgets for Zero-Downtime Upgrades

A Pod Disruption Budget (PDB) is a policy that tells Kubernetes the minimum number of pods that must stay running during voluntary disruptions — node drains, cluster upgrades, and rolling deployments. Without one, a node drain can terminate all pods of a service simultaneously, causing a complete outage.

Explore

Debugging Kubernetes Networking with kubectl and CNI Plugins

Diagnose and fix Kubernetes pod networking failures, DNS resolution issues, and CNI plugin misconfigurations using kubectl, netshoot, and network policy debugging tools.

Explore

Implementing Kubernetes Deployment Strategies - Rolling, Blue-Green, and Canary

Learn how to deploy new application versions to Kubernetes with zero downtime using rolling updates, blue-green switching, and canary traffic splitting.

Explore

Implementing Kubernetes Pod Security Standards and securityContext

Secure Kubernetes pods using Pod Security Standards, securityContext settings, and runtime controls that prevent privilege escalation and container breakout attacks.

Explore

Implementing Liveness and Readiness Probes for Zero-Downtime Deploys

Configure liveness, readiness, and startup probes in Kubernetes to eliminate downtime during rolling deployments and protect production traffic from unhealthy pods.

Velero vs etcd Snapshot: Not a Real Choice

Velero and etcd snapshots protect different layers of a cluster, not the same thing. Here's what each covers and why production DR needs both.

Istio Ambient vs Linkerd in 2026

Istio Ambient killed the sidecar-tax argument. The real 2026 decision is waypoint topology and Buoyant's licensing shift, not features vs simplicity.

Nginx Ingress vs Traefik vs Gateway API in 2026

Ingress-nginx retired in March 2026. Here's how Traefik and the Gateway API actually compare as replacements — and why "just swap it" is the wrong frame.

OPA Gatekeeper vs Kyverno: Policy Engine in 2026

OPA Gatekeeper vs Kyverno compared for 2026 - Rego vs YAML, mutation maturity, operational overhead, and which policy engine fits your cluster.
