A complete guide to the KEDA Helm chart: what it deploys, how to install and verify it, key values.yaml parameters, HA setup, hardening, GitOps, and safe upgrades and uninstalls.

One pod on a shared node can starve its neighbors of CPU and memory. Here is how eviction really works, and the requests, limits, quotas, and right-sizing habits that stop it.

A practical guide to Kubernetes ErrImagePull and ImagePullBackOff errors: how image pulls work, the common causes, how to diagnose them, and the fixes for each.

Cast AI's autoscaler applies stale sizing on new releases, stores config in app manifests, and stops at the cluster edge. Here is how PerfectScale addresses all three, with sources.

A complete guide to kubectl rollout: how Kubernetes executes rollouts with ReplicaSets, every subcommand with examples, why rollouts get stuck, and production best practices.

Cutting resources based on stale usage data leads to OOM kills and throttling. Learn how revision-aware, guardrailed optimization delivers safe savings on every deploy.
