OPA Configuration Examples

Configuration Examples

Enable on a service

Enable on a route

Enable globally

The following examples provide some typical configurations for enabling the opa plugin on a service.

Admin API

Kubernetes

Declarative (YAML)

Make the following request:

curl -X POST http://localhost:8001/services/SERVICE_NAME|SERVICE_ID/plugins \
    --data "name=opa"  \
    --data "config.opa_host=localhost"  \
    --data "config.opa_port=8181"  \
    --data "config.opa_path=/v1/data/example/kong/allowBoolean"

Replace SERVICE_NAME|SERVICE_ID with the id or name of the service that this plugin configuration will target.

First, create a KongPlugin resource:

echo "
apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: opa-example
plugin: opa
config:
  opa_host: localhost
  opa_port: 8181
  opa_path: "/v1/data/example/kong/allowBoolean"
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the service as follows:

kubectl annotate service SERVICE_NAME konghq.com/plugins=opa-example

Replace SERVICE_NAME with the name of the service that this plugin configuration will target. You can see your available ingresses by running kubectl get service.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:
- name: opa
  service: SERVICE_NAME|SERVICE_ID
  config:
    opa_host: localhost
    opa_port: 8181
    opa_path: "/v1/data/example/kong/allowBoolean"

Replace SERVICE_NAME|SERVICE_ID with the id or name of the service that this plugin configuration will target.

The following examples provide some typical configurations for enabling the opa plugin on a route.

Admin API

Kubernetes

Declarative (YAML)

Make the following request:

curl -X POST http://localhost:8001/routes/ROUTE_NAME|ROUTE_ID/plugins \
    --data "name=opa"  \
    --data "config.opa_host=localhost"  \
    --data "config.opa_port=8181"  \
    --data "config.opa_path=/v1/data/example/kong/allowBoolean"

Replace ROUTE_NAME|ROUTE_ID with the id or name of the route that this plugin configuration will target.

First, create a KongPlugin resource:

echo "
apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: opa-example
plugin: opa
config:
  opa_host: localhost
  opa_port: 8181
  opa_path: "/v1/data/example/kong/allowBoolean"
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the ingress as follows:

kubectl annotate ingress INGRESS_NAME konghq.com/plugins=opa-example

Replace INGRESS_NAME with the name of the ingress that this plugin configuration will target. You can see your available ingresses by running kubectl get ingress.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:
- name: opa
  route: ROUTE_NAME|ROUTE_ID
  config:
    opa_host: localhost
    opa_port: 8181
    opa_path: "/v1/data/example/kong/allowBoolean"

Replace ROUTE_NAME|ROUTE_ID with the id or name of the route that this plugin configuration will target.

A plugin which is not associated to any service, route, or consumer is considered global, and will be run on every request. Read the Plugin Reference and the Plugin Precedence sections for more information.

The following examples provide some typical configurations for enabling the OPA plugin globally.

Admin API

Kubernetes

Declarative (YAML)

Make the following request:

curl -X POST http://localhost:8001/plugins/ \
    --data "name=opa"  \
    --data "config.opa_host=localhost"  \
    --data "config.opa_port=8181"  \
    --data "config.opa_path=/v1/data/example/kong/allowBoolean"

Create a KongClusterPlugin resource and label it as global:

apiVersion: configuration.konghq.com/v1
kind: KongClusterPlugin
metadata:
  name: <global-opa>
  annotations:
    kubernetes.io/ingress.class: kong
  labels:
    global: "true"
config:
  opa_host: localhost
  opa_port: 8181
  opa_path: "/v1/data/example/kong/allowBoolean"
plugin: opa

Add a plugins entry in the declarative configuration file:

plugins:
- name: opa
  config:
    opa_host: localhost
    opa_port: 8181
    opa_path: "/v1/data/example/kong/allowBoolean"
