While GitOps has brought consistency and innovation to Kubernetes deployments, its reliance on git-based workflows and tools like ArgoCD and Flux still leaves important challenges unsolved. This article explores both the real-world progress and the limitations of GitOps, from deployment strategies and multi-cluster rollouts to issues around permissions, secrets management, and the need for solutions that go beyond git as the sole source of truth.

Upgrading from Node.js 18 to 20 brought unexpected performance impacts to a Kubernetes-deployed service, as detailed in this technical recap. The experience-driven story reveals how changing memory reservations on Kubernetes pods can shrink Node.js heap spaces—specifically the "new space"—triggering heavier garbage collection and higher CPU load, and how adjusting the --max-semi-space-size parameter restored both speed and stability.
