Hi Team, Referring to this link [Kong Spec Expose - Plugin | Kong Docs](https://docs.konghq.com/hub/optum/kong-spec-expose/) how to configure this plugin if its a k8s cluster which is connecting via KUBCONFIG from windows machine? please share insights here. (kong version is 2.8) kong-spec-expose plugin is not available in “enabled\_plugins” list . my understanding is, installation process ([Kong Spec Expose - Plugin | Kong Docs](https://docs.konghq.com/hub/optum/kong-spec-expose/#installation)) will get enabled and below yaml file to apply on kubernetes cluster globally apiVersion: [configuration.konghq.com/v1](http://configuration.konghq.com/v1) kind: KongClusterPlugin metadata: name: kong-spec-expose annotations: [kubernetes.io/ingress.class:](http://kubernetes.io/ingress.class:) kong labels: global: “true” config: spec\_url: [OpenAPI-Specification/examples/v2.0/json/petstore.json at main · OAI/OpenAPI-Specification · GitHub](https://github.com/OAI/OpenAPI-Specification/blob/master/examples/v2.0/json/petstore.json) plugin: kong-spec-expose Link :[plugin configuration · Issue #12 · Optum/kong-spec-expose · GitHub](https://github.com/Optum/kong-spec-expose/issues/12) please share some pointers on this … ---

KongClusterPlugin resources only configure plugins; they do not install them. You’ll want to instead store the plugin files in a ConfigMap and then use [charts/values.yaml at 1f5011ecca812f57c8d8e489c0eedc1a95c086b2 · Kong/charts · GitHub](https://github.com/Kong/charts/blob/1f5011ecca812f57c8d8e489c0eedc1a95c086b2/charts/kong/values.yaml#L364-L383) to load it. You can alternately build a custom Docker image using the stock Kong image as a base and running `luarocks install kong-spec-expose`. You’ll need to set a `plugins` value under the `env` block that includes it with this method. ---

Hi Travis, I’m not preferring this solution to rebuild docker image after adding this plugin. merely looking for the easy option to deploy this plugin (reference in yaml to get enabled in plugins-list )into Kong gateway which is residing on k8s cluster. ---
