KEYNOTE: Taking a step back and leveraging GitOps to wrangle your clusters and projects
summary
Argues GitOps is the de facto way to manage multiple Kubernetes/OpenShift clusters, with Git as auditable source of truth and a poll-based many-to-one model that scales and works in air-gapped environments. Shows installing Argo CD on OpenShift from manifests, creating a GUI-backed app for a site link and a simple Python Flask app updated v1→v2, and demonstrates sync modes (manual vs automatic). Demo has an autosync timing hiccup but the Argo‑CD-driven deployment and cluster federation succeed.
