summary
Defines GitOps as Git as the single source of truth and an agent that ensures the cluster matches that repo, and walks through a hands-on lab using Argo CD, kustomize and GitHub to deploy and roll back apps. Demonstrates sealed secrets for encrypted values, shows a live DigitalOcean cluster with roughly 1,200 developers, ~160 clusters and ~1,300 deployments/day, and runs about 200 simultaneous app syncs in the workshop — deployments and rollbacks succeed and troubleshooting via the Argo UI proves effective.
