1.1.17 Ensure that the --audit-log-maxage argument is set to 30 or as appropriate

Information

Retain the logs for at least 30 days or as appropriate.

Rationale:

Retaining logs for at least 30 days ensures that you can go back in time and investigate or correlate any events. Set your audit log retention period to 30 days or as per your business requirements.

Solution

Edit the `/etc/kubernetes/apiserver` file on the master node and set the `KUBE_API_ARGS` parameter to `'--audit-log-maxage=30'`: `KUBE_API_ARGS='--audit-log-maxage=30'`

Based on your system, restart the `kube-apiserver` service. For example: `systemctl restart kube-apiserver.service`

Impact:

None
