helm repo update

Then, use the following Terraform configuration to deploy the Prometheus Operator. Note, we’re utilizing theChainguard prometheus operator image, as well as the Chainguard kube-webhook-certgen image:

helm install prometheus-operator prometheus-community/kube-prometheus-stack \
  --set prometheusOperator.image.registry=cgr.dev \
  --set prometheusOperator.image.repository=chainguard/prometheus-operator \
  --set prometheusOperator.image.tag=latest
  --set prometheusOperator.admissionWebhooks.patch.image.registry=cgr.dev \
