GitOps with Argo CD: The Reconciliation Loop That Survives 3 a.m.

Tue, 19 May 2026 13:30:00 -0300

Here’s the test I use for any deployment tooling:

It is 3 a.m. on a Sunday. PagerDuty just woke you up. A production service is degraded. You roll out of bed, open your laptop, and have to figure out what the cluster thinks is true, what’s actually true, and what changed in the last twelve hours. The faster you can answer those three questions, the better the tooling.

The right GitOps stack collapses all three questions into one dashboard. The wrong one has you SSH-hopping between five servers running kubectl rollout history against unlabeled deployments. I’ve done both. I’m writing this post about the former.
