GitOps Syllabus: Working Our Way Through the Lesson Plan
summary
Devtools at Teachers Pay Teachers migrates ~100 services to GitOps using Argo CD, Helm, EKS and Codefresh and reports deployments under 30 minutes with no major rollouts failures. Team keeps Helm charts in app repos initially, uses CI to make GitOps commits that bump staging then pause for prod approval, then moves image tags via ArgoCD application overrides to avoid changing charts. They try app-of-apps, abandon it for kubectl apply after sync failures, enable prune, and run syncs triggered by CI—overall successful and incremental.
