Question

Your team manages a production application with Argo CD. The Application resource has both automated sync and self-heal enabled. An on-call engineer, responding to an incident, manually runs 'kubectl scale deployment web --replicas=8' to handle a traffic spike. The Git manifest still declares 3 replicas. What will Argo CD do?

Accepted Answer

Detect the drift and revert the deployment back to 3 replicas to match the Git manifest

Answer

Update the Git repository to reflect the new value of 8 replicas

Answer

Leave the deployment at 8 replicas and mark the Application as OutOfSync without changing anything

Answer

Scale the deployment to the average of 3 and 8 replicas
