GitOps Approaches and Trade-offs

on YouTube ↗35m

" summary

Covers concrete GitOps decisions: choose trunk-based development over branch-per-environment, keep an environment folder per repo, use Helm or Kustomize for templating, and keep secrets out of Git with a secrets manager. Compares push vs pull deployment models and trade-offs (cross-target CI power vs pull’s cluster-side sync). Recommends automated validation and parallel tests, describes blue/green and 1% canary ramp to 100% for low blast radius, and flags scale pain: 400 clusters running four incompatible versions.
