0.22.0 - unable to initialize a remote image scanner

[ChanduReddy123]

What steps did you take and what happened:
we've recently installed the trivy operator (v0.22.0) in our AWS EKS cluster (v1.30.7)
with the following values.yaml

trivy:
  ignoreUnfixed: true
  server:
    securityContext:
      allowPrivilegeEscalation: false
excludeNamespaces: "kube-system"
operator:
  builtInTrivyServer: true

trivyOperator:
  scanJobPodTemplatePodSecurityContext:
    RunAsUser: 10000
    RunAsGroup: 10000
    RunAsNonRoot: true

podAnnotations:
  prometheus.io/scrape: "true"
  prometheus.io/port: "8080"
  prometheus.io/path: "/metrics"
  prometheus.io/scrape_interval: "5m"

podSecurityContext:
  runAsUser: 65534
  runAsNonRoot: true
  fsGroup: 65534

nodeCollector:
  useNodeSelector: false

used the following command to install the trivy operator

helm install trivy-operator aqua/trivy-operator \
                                        --namespace trivy-system \
                                        --create-namespace \
                                        --version 0.24.0 \
                                        --values values.yaml

we keep getting errors in the trivy-operator pod and few scan job pods exit with error

The error in the trivy-operator is as follows

we also tried to run the scan pods with root user but we still got the similar error.

we were also getting the issues with kube-system namespace pods so for time being we've excluded the namespace from the scan

What did you expect to happen:
no errors recorded in the trivy-operator pod and vulnerability report to be generated for all the images running in the cluster

Environment:

• Trivy-Operator version (v0.22.0):
• Kubernetes version (v1.30.7):
• OS (Linux amd64 Amazon Linux 2023.6.20241121):

This error seems to be related to missing permissions to pull the image auto from dockerhub:

remote error: GET https://index.docker.io/v2/library/auto/manifests/latest: UNAUTHORIZED: authentication required;

If get a similar error when trying to pull the image directly:

$ podman pull docker.io/library/auto:latest
Trying to pull docker.io/library/auto:latest...
Error: initializing source docker://auto:latest: reading manifest latest in docker.io/library/auto: requested access to the resource is denied

[ChanduReddy123]

we never used any image auto in our deployments
auto image is related to the istio
I don't think it is private image

You are right, auto is just a placeholder. See here. So trivy will neither be able to pull or scan the image. It seems like the problem is more related to the istio configuration.
