Daily DevOps Interview Questions Day #70

Daily Interview Questions for SRE and DevOps engineers

Question of the day:

This one tripped up our team last week. You’re using ArgoCD for GitOps deployments to Kubernetes. A developer pushes a change to the main branch updating an environment variable in a deployment. ArgoCD shows the app as “Synced” and “Healthy,” but when you check the running pods, they’re still using the old environment variable value.

• ArgoCD UI shows green checkmarks everywhere

• kubectl get pods shows all pods are Running

• But the application is behaving as if the config never changed

Let’s walk through this troubleshooting scenario together.
