Challenge
Configure Admission Control
The cluster needs to be configured to scan incoming container images before running workloads. An image scanning service is already set up.
Modify the admission control configuration so that it will implicitly deny images, even if the image scanning service is unreachable. The global admission control configuration is at
/etc/kubernetes/admission-control/admission-control.conf
, and the specific configuration for the admission controller is at/etc/kubernetes/admission-control/imagepolicy.conf

Challenge
Set the URL of the Image Scanning Service
Add the URL of the image scanning service to the
kubeconfig
used by the admission controller.The service can be reached at
https://acg.trivy.k8s.webhook:8090/scan

Challenge
Enable the Admission Control Plugin(s)
In the
kube-apiserver
manifest, enable any admission control plugin(s) necessary to scan images.There are two Pod manifests in
/home/cloud_user
on the CLI server. If your setup is working,no-vulns-pod.yml
should pass image validation, whilevulns-pod.yml
should fail due to vulnerabilities.
