Hi @mrafi

I just checked it, and it’s working fine on my end. Could you please share the validation error and your YAML file? Here’s the YAML file that worked for me.

apiVersion: v1
kind: Namespace
metadata:
  name: datacenter
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: time-config
  namespace: datacenter
data:
  TIME_FREQ: "11"
---
apiVersion: v1
kind: Pod
metadata:
  name: time-check
  namespace: datacenter
spec:
  containers:
    - name: time-check
      image: busybox:latest
      command: ["/bin/sh", "-c"]
      args:
        - while true; do date >> /opt/itadmin/time/time-check.log; sleep $TIME_FREQ; done
      env:
        - name: TIME_FREQ
          valueFrom:
            configMapKeyRef:
              name: time-config
              key: TIME_FREQ
      volumeMounts:
        - name: log-volume
          mountPath: /opt/itadmin/time
  volumes:
