From Chaos To Control: GitOps Disaster Recovery With the OpenSearch Operator

on YouTube ↗30m

" summary

Shows that the OpenSearch Operator plus a GitOps pipeline actually restores a full cluster state — CRDs, node pools, security, index templates and scheduled snapshots — after a deliberate cluster delete and the demo restores everything successfully. Uses Kubernetes 1.34, OpenSearch 2.8.0 manifests and Argo CD to sync YAML from Git; repo contains concrete YAML and a DR checklist. Notes the S3 plugin must be added after operator brings up plugins and that snapshots and configuration are both required and have point‑in‑time limits.
