Monitoring base image cache

[Jan Kosecki]

Hi,

I understand one needs to use kaniko warmer to populate shared volume with base images that can be used later on by executor instead of pulling from a registry. I'm wondering if there exists a way to extract information from executor (and not via parsing its output logs) to let me know if for a specific Dockerfile a base image was extracted from external registry or found in the cache. 

My reasoning behind is that as company expands and new images are used, I'd like to have an automated way of telling me that there are some base images used that haven't been provided by kaniko warmer.

Thanks,
Jan
