Helm OPA Plugin

This plugin enables you to check your rendered templates files again Open Policy Agent policies to ensure that they match your policies.

Usage

Define policies inside the policies folder in your Chart. e.g. Pods must run as nonRoot:

deny[msg] {
  input.kind = "Deployment"
  not input.spec.template.spec.securityContext.runAsNonRoot = true
  msg = "Containers must not run as root"
}

Run the policy check:

# helm opa CHART
Processing file deployment.yaml
Violations:
- Containers must not run as root
Processing file ingress.yaml
Processing file service.yaml
===
Result: Chart is not compliant
