Setting a Storage Limit for Trivy Server Cache in Kubernetes

[dimitriospapadimas]

Question

Hello,

We have deployed Trivy Server in our Kubernetes cluster using the official Helm charts from this repository. We have not enabled Redis for caching and are using the default filesystem option instead. Given that we have a specified storage capacity, we are wondering if there is a way to configure a space limit for the cache ( apart from the pv ).

If the cache size exceeds the available filesystem storage, how does Trivy handle this situation? Will it gracefully manage the storage, or could it result in crashes? If there are any recommended approaches to prevent potential issues, please let us know.

Thanks in advance!

IIUC Scalable cache is out of scope OSS, so I can take a look at Aqua's commercial product:
