Kubernetes Pod CrashLoopBackOff — Missing ConfigMap
A Kubernetes deployment enters CrashLoopBackOff because a ConfigMap was deleted during a cleanup script. The application cannot start without its configuration, and the backoff timer keeps increasing.

Scenario Conditions
Kubernetes 1.28. Deployment with 3 replicas. ConfigMap 'app-config' deleted accidentally. Pod restarts: 47 in last 30 minutes. Backoff timer at 5 minutes.
Injected Error Messages (1)
CrashLoopBackOff on deployment prod-api — crash loop detected, 47 restarts in 30 minutes, container exit code 1, missing required config file /etc/app/config.yaml, service restart failing repeatedly, pod crashloopbackoff state
Neural Engine Root Cause Analysis
The prod-api deployment is in a CrashLoopBackOff state due to a missing required configuration file at /etc/app/config.yaml. The application container starts, fails to find the required config file, exits with code 1, and Kubernetes restarts it repeatedly (47 times in 30 minutes). This is a configuration management issue rather than a resource or code problem, indicating either missing ConfigMap/Secret mounts or incorrect volume configurations in the deployment manifest.
Remediation Plan
1. Verify if config.yaml ConfigMap exists in the namespace using 'kubectl get configmaps' 2. If missing, create the ConfigMap with required application configuration 3. Check deployment manifest to ensure ConfigMap is properly mounted as volume at /etc/app/config.yaml 4. If mount exists but path is wrong, update deployment to correct the volumeMount path 5. Apply corrected deployment configuration 6. Monitor pod startup and verify application health endpoint
