OPA is a general-purpose policy engine that let’s you offload decisions from your service. To do so, OPA needs to have access to policies and data that it can use to make decisions.
Prior to v0.8, OPA only exposed low-level HTTP APIs that let you push policy and data into the engine. With v0.8, we’re excited to provide new management features in OPA which make it easier to distribute policies (and data) as well as monitor the health of your agents.
