Magento2: How to execute Cron in non-root container on Kuberentes?

I’ve used Bitnami Magento Helm chart to install Magento 2 on the Kubernetes cluster. By default the pod and the container are configured not to use root user which is good from a security point of view. But because of running as a non-root user, Magento can’t execute Cron jobs. Are there any ways to execute Cron using a non-root user? Why can’t a non-root user execute Cron?
