GitOps

Your cluster is gone. Complete failure. The cloud region is down, the hardware died, or someone ran the wrong terraform destroy. Everything is gone. Now what? If you’ve been doing GitOps right, the answer is: spin up a new cluster, point ArgoCD at Git, wait. Your entire infrastructure recreates itself. This is the ultimate promise of GitOps: Git is your backup. Why GitOps Changes Disaster Recovery Traditional DR involves: Regular backups of cluster state Backup storage (etcd snapshots, Velero backups) Tested restore procedures Recovery time measured in hours GitOps DR is different: ...

“Should I use ArgoCD or Flux?” I’ve been asked this question dozens of times. The honest answer: both are excellent. The real question is which fits your context better. I use ArgoCD. But that’s a choice based on my specific needs, not a universal truth. Let me explain both tools, their philosophies, and help you decide.

You have to query the cluster. Configuration drift happens silently. Rollbacks are manual and error-prone. There’s no audit trail beyond “someone ran kubectl.” ...
