Trivy on Microk8s

microk8s enable community
microk8s enable trivy
kubectl get pod -n trivy-system

It might take awhile for trivy to adjust pods to your k8s size but when all pods are in a healthy state run

kubectl get vulnerabilityreports --all-namespaces -o wide
kubectl -n test describe vulnerabilityreports replicaset-foo
ns=test; kubectl -n $ns delete replicaset $(kubectl -n $ns get replicaset -o jsonpath='{ .items[?(@.spec.replicas==0)].metadata.name }')
# or
kubectl config set-context --current --namespace=test
kubectl delete replicaset $(kubectl get replicaset -o jsonpath='{ .items[?(@.spec.replicas==0)].metadata.name }')

To blow out namespace

kubectl delete all --all -n test

Get reports
