auth0-jhipster-k8s-eks-microservices-example
A microservice sample application configured to use Auth0 for OIDC and Terraform scripts to deploy to AWS EKS
You can find all the code shown in this tutorial on GitHub in the @oktadev/auth0-java-microservices-examples repository. The OpenFeign example with Spring MVC is in the spring-boot-gateway-mvc directory. The Spring Cloud Gateway with WebFlux is in spring-boot-gateway-webflux. The Keycloak example is in the keycloak branch.
At startup, these properties will be read using spring-dotenv.
An easy way to get a pre-configured Keycloak instance is to use JHipster's jhipster-sample-app-oauth2 application. It gets updated with every JHipster release. You can clone it with the following command:
Okta also now has an Okta Spring Boot starter. I didn't use it in my first experiment, but I'm a big fan of it after the last few years! It dramatically simplifies configuration and makes securing your apps with OAuth 2.0 and OIDC easy. It's a thin wrapper around Spring Security's resource server, OAuth client, and OIDC features. Not only that, but it works with Okta Workforce Identity, Okta Customer Identity (aka Auth0), and even Keycloak.
I created all of these applications using start.spring.io's REST API and HTTPie.
Spring Cloud Gateway MVC 2023.0.0 doesn't allow you to configure a TokenRelay filter in YAML, so I added a RouterFunction bean to add it.
To run the example, you must install the Auth0 CLI and create an Auth0 account. If you don't have an Auth0 account, sign up for free. I recommend using SDKMAN! to install Java 17+ and HTTPie for making HTTP requests.

You can see the access token's contents by copying/pasting it into jwt.io. You can also access the car service directly using it.
