Keeping disk pressure under control is a day-to-day chore for cluster admins. Left unchecked, old container images, completed builds, logs and stray volumes will quietly eat through node storage and the internal registry PVC, eventually triggering pod evictions or broken pushes. This post walks through a layered strategy for reclaiming and preventing waste—starting with the integrated image registry and ending with node-level log rotation.

Argo CD and GitOps: Setting Up Continuous Delivery on a Kubernetes Cluster 0

- June 10, 2025
Argo CD is an open-source GitOps continuous delivery tool for Kubernetes. In GitOps, all deployment manifests live in a Git repo as the source of truth. Argo CD continuously monitors the Git repo and the Kubernetes cluster, and automatically (or manually) syncs the live state to match the desired state in Git. It also provides a web-based UI to see “desired vs live” status of your applications. In this tutorial, we’ll install Argo CD on a local Minikube cluster, access the Argo CD web UI, and deploy a sample GitOps application (a simple NGINX example) from a public repository.
