The output of a Wasm module built this way contain the result of evaluating the In this opa_eval_ctx_set_input exported function supplying the evaluation context It can be a boolean value or json. This allows anyone to read and modify the source code to fit their needs, for personal user or commercial applications. The OPA documentation is an excellent resource, both for learning Rego as well as a reference to use when authoring or reviewing policy. Additionally, the playground allows evaluating policies with coverage, showing exactly which rules and lines are being evaluated given the input and data provided in the user interface. request/response formats. Using tools like wasm-objdump (wasm-objdump -x policy.wasm), the ABI In the case of remove and replace operations, the effective path MUST refer to an existing document, otherwise the server returns 404.

Centralized management OPAs management APIs allow for OPA to pull policy and data bundles, report health and status and send decision logs, from/to a central control plane component, such as the Styra Declarative Authorization Service (DAS). We will create a bundle of those policies and data.json created above by running the OPA build in the same folder as the policy files. The rego package exposes different options for customizing how policies are compilers and evaluators. The request body contains an object that specifies a value for The input Document.

Import agentkeepalive module: Import agentkeepalive module and store returned instance into a variable. (when OPA is ready to receive traffic). Evaluation has less overhead than the REST API (because it is evaluated in the same operating-system process) and should outperform the Go API (because the policies have been compiled to a lower-level instruction set). query_id.
