How to fix emptyDir volume size limit exceeded, pod evicted in Kubernetes

KubernetesBEGINNERMEDIUM

Pod emptyDir volume exceeds sizeLimit. Fix by increasing limit, reducing data written, or using persistent volume.

What this error means

emptyDir volumes can fill up quickly if applications write logs or temporary files. When limit is exceeded, pod is evicted.

1Check emptyDir configuration

bash

kubectl get pod -n <namespace> <pod-name> -o yaml | grep -A 5 emptyDir

2Increase sizeLimit

yaml

volumes:
- name: tmp
  emptyDir:
    sizeLimit: 500Mi  # Increased

3Reduce data written

Configure log rotation and cleanup.

4Use persistent volume for large data

Use PVC for data exceeding emptyDir limits.

emptyDir with medium: Memory defaults to 50% of node memory.
