...
Use the OPA Rego library to integrate OPA into the Go application.
Establish a secure communication channel between the Go application and OPA.
Develop a clear and concise mechanism for defining policies using the OPA Rego language within the Go application.
Implement logic for evaluating policies using the OPA Rego engine.
Enable the Go application to dynamically load and update policies from OPA for real-time adjustments.
Implement Kafka producers to publish policy-related events when policy decisions are made.
Implement Kafka consumers to listen for policy-related events and trigger appropriate actions.
Approach 2: Java Sidecar Integration with OPA
...
Conclusion: Both approaches involve integrating OPA for policy enforcement, with the second first approach additionally incorporating Kafka for event-driven communication. The choice between a Java sidecar and a Go application is yet to be decided.
