Fall back to limited k8s summary report if secret access permission is missing

[nika-pr]

Description

I would like to analyse a GKE cluster where I was granted Kubernetes Engine Cluster Viewer and Kubernetes Engine Viewer on the project level.
When I try to run trivy k8s --report=summary cluster, I get the following error:

FATAL get k8s artifacts with node info error: failed getting auth for gvr: apps/v1, Resource=daemonsets - getting secret by name: kube-system/private-registry-creds: secrets "private-registry-creds" is forbidden: User "<REDACTED>" cannot get resource "secrets" in API group "" in the namespace "kube-system": requires one of ["container.secrets.get"] permission(s).

Is secret scanning absolutely necessary for any kind of report? I'd imagine some results can be found without scanning them.

Expected behavior: WARN log that tells me the results are limited due to missing permissions, but a "limited" report being provided as output nonetheless.

Target

Kubernetes

Scanner

None

@nika-pr secrets are used in case images to be pulled from private registry , in your case it should not fail on this error , converting to issue #5682
