# subscription-validator-webhook This is an example of a [Validating Admission Plugin](https://docs.openshift.com/container-platform/4.12/architecture/admission-plug-ins) to validate subscriptions for certain operators against a list of channels that you want to allow subscriptions against. ## How to Build and Deploy The webhook is written in Quarkus. There are a few ways to build and deploy Quarkus apps. The approach below uses Quarkus plugins to build the container image, followed by a Helm chart to deploy and configure the Validating Webhook. The Helm chart approach is used for deployment to more easily add a serving certificate (admission webhook must have TLS) and map in config for the webhook. ### Build the Container Image To build the webhook as a JVM image: ```shell script ./mvnw clean package -Dquarkus.container-image.build=true [-Dquarkus.kubernetes-client.trust-certs=true] ``` ### Deploy and Configure the Webhook To deploy the webhook image and configure the Validating Webhook: ```shell script helm install ./chart ``` ## === Standard Quarkus generated README below === This project uses Quarkus, the Supersonic Subatomic Java Framework. If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ . ## Running the application in dev mode You can run your application in dev mode that enables live coding using: ```shell script ./mvnw compile quarkus:dev ``` > **_NOTE:_** Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/. ## Packaging and running the application The application can be packaged using: ```shell script ./mvnw package ``` It produces the `quarkus-run.jar` file in the `target/quarkus-app/` directory. Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/quarkus-app/lib/` directory. The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`. If you want to build an _über-jar_, execute the following command: ```shell script ./mvnw package -Dquarkus.package.type=uber-jar ``` The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`. ## Creating a native executable You can create a native executable using: ```shell script ./mvnw package -Pnative ``` Or, if you don't have GraalVM installed, you can run the native executable build in a container using: ```shell script ./mvnw package -Pnative -Dquarkus.native.container-build=true ``` You can then execute your native executable with: `./target/subscription-validator-webhook-1.0.0-SNAPSHOT-runner` If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling. ## Related Guides - RESTEasy Reactive ([guide](https://quarkus.io/guides/resteasy-reactive)): A JAX-RS implementation utilizing build time processing and Vert.x. This extension is not compatible with the quarkus-resteasy extension, or any of the extensions that depend on it. ## Provided Code ### RESTEasy Reactive Easily start your Reactive RESTful Web Services [Related guide section...](https://quarkus.io/guides/getting-started-reactive#reactive-jax-rs-resources)
