Providers

Providers are the policy engines which evaluate the input data from the specified domain. Currently supported Providers are:

• OPA (Open Policy Agent)
• Kyverno

The provider block of a Lula Validation is given as follows, where the sample is indicating the OPA provider is in use:

# ... Rest of Lula Validation
provider:
    type: opa   # opa or kyverno accepted
    opa-spec:
        # ... Rest of opa-spec
# ... Rest of Lula Validation

Each domain specification retreives a specific dataset, and each will return that data to the selected Provider in a domain-specific format. However, this data will always take the form of a JSON object when input to a Provider. For that reason, it is important that Domain and Providerspecifications are not built wholly independently in a given Validation.
