Trivy supports two types of Helm scanning, templates and packaged charts. The following scanners are supported.

Format Misconfiguration Secret
Chart -


Trivy recursively searches directories and scans all found Helm files.

It evaluates variables, functions, and other elements within Helm templates and resolve the chart to Kubernetes manifests then run the Kubernetes checks. See here for more details on the built-in policies.

Value overrides

There are a number of options for overriding values in Helm charts. When override values are passed to the Helm scanner, the values will be used during the Manifest rendering process and will become part of the scanned artifact.

Setting inline value overrides

Overrides can be set inline on the command line

trivy conf --helm-set securityContext.runAsUser=0 ./charts/mySql

Setting value file overrides

Overrides can be in a file that has the key=value set.

# Example override file (overrides.yaml)

  runAsUser: 0
trivy conf --helm-values overrides.yaml ./charts/mySql

Setting value as explicit string

the --helm-set-string is the same as --helm-set but explicitly retains the value as a string

trivy config --helm-set-string name=false ./infrastructure/tf

Setting specific values from files

Specific override values can come from specific files

trivy conf --helm-set-file environment=dev.values.yaml ./charts/mySql


The secret scan is performed on plain text files, with no special treatment for Helm. Secret scanning is not conducted on the contents of packaged Charts, such as tar or tar.gz.
