We need to implement a simple sidecar to be executed together with the function container which will be collecting logs from the pod. 

1. It will be collecting all kubenetes events related to the function instances. 
2. It will be monitoring internal logs file (e.g. /var/log/function.log) which will be shared  between function container and sidecar. Everything written there  will be collected and passed trough to the proper audit log.
