Configuration
You can configure Trivy-Operator to control it's behavior and adapt it to your needs. Aspects of the operator machinery are configured using environment variables on the operator Pod, while aspects of the scanning behavior are controlled by ConfigMaps and Secrets.

---|---|---|---|
OwnNamespace | operators |
operators |
The operator can be configured to watch events in the namespace it is deployed in. |
SingleNamespace | operators |
foo |
The operator can be configured to watch for events in a single namespace that the operator is not deployed in. |
MultiNamespace | operators |
foo,bar,baz |
The operator can be configured to watch for events in more than one namespace. |
AllNamespaces | operators |
(blank string) | The operator can be configured to watch for events in all namespaces. |
Example - configure namespaces to scan
To change the target namespace from all namespaces to the default
namespace edit the trivy-operator
Deployment and change the value of the OPERATOR_TARGET_NAMESPACES
environment variable from the blank string (""
) to the default
value.

Example - patch ConfigMap
By default Trivy displays vulnerabilities with all severity levels (UNKNOWN
, LOW
, MEDIUM
, HIGH
, CRITICAL
). To display only HIGH
and CRITICAL
vulnerabilities by patching the trivy.severity
value in the trivy-operator-trivy-config
ConfigMap:
kubectl patch cm trivy-operator-trivy-config -n trivy-system \
--type merge \
-p "$(cat <<EOF
{
"data": {
"trivy.severity": "HIGH,CRITICAL"
}
}
EOF
)"
Example - patch Secret
To set the GitHub token used by Trivy scanner add the trivy.githubToken
value to the trivy-operator-trivy-config
Secret:
kubectl patch secret trivy-operator-trivy-config -n trivy-system \
--type merge \
-p "$(cat <<EOF
{
"data": {
"trivy.githubToken": "$(echo -n <your token> | base64)"
}
}
EOF
)"
Example - delete a key
The following kubectl patch
command deletes the trivy.httpProxy
key:
kubectl patch cm trivy-operator-trivy-config -n trivy-system \
--type json \
-p '[{"op": "remove", "path": "/data/trivy.httpProxy"}]'
