Event Information

​
Meaning

  • The “Write below rpm database” event in a Kubernetes cluster indicates that a process running within a container attempted to modify the RPM database located in the host system.
  • This event could potentially indicate unauthorized or malicious activity, as modifying the RPM database can lead to tampering with the installed packages and compromising the integrity of the system.
  • To investigate this event, you can use the following commands:
    1. List all running pods in the cluster: kubectl get pods -A
    2. Check the logs of the suspicious pod: kubectl logs <pod_name> -n <namespace>
    3. Inspect the container’s filesystem within the pod: kubectl exec -it <pod_name> -n <namespace> -- sh

​
Remediation

To remediate the event “Write below rpm database using python kubernetes api”, you can follow these steps:

  1. Identify the affected pod:

    • Use the kubectl get pods command to list all the pods in the cluster.
    • Look for the pod that triggered the event based on the pod name or labels.

  2. Delete the affected pod:

    • Use the kubectl delete pod <pod-name> command to delete the affected pod.
    • Kubernetes will automatically create a new pod to replace the deleted one.

  3. Apply the correct Kubernetes manifest file:

    • Create a new Kubernetes manifest file (e.g., remediation.yaml) with the correct configuration for the pod.
    • Use the kubectl apply -f remediation.yaml command to apply the new manifest file and create a new pod.

Note: Make sure to update the manifest file with the correct image, environment variables, volumes, and any other required configurations for your specific use case.
