Secure Kafka Streams with Quarkus and Java

A Kafka Streams example app that shows how to create secure Java REST endpoints with Quarkus and communicate securely with Kafka.

Please read Secure Kafka Streams with Quarkus and Java to see how this app was created.

Prerequisites: Java 11.

Okta has Authentication and User Management APIs that reduce development time with instant-on, scalable user infrastructure. Okta's intuitive API and expert support make it easy for developers to authenticate, manage, and secure users + roles in any application.

Getting Started

To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/okta-kafka-streams-quarkus-example.git
cd okta-kafka-streams-quarkus-example/quarkus-client

This will get a copy of the project installed locally. To run the example, run the following command:

./mvnw compile quarkus:dev

Create an OIDC App in Okta

You will need to create an OIDC App in Okta to get a clientId to generate a JWT for authentication.

Log in to your Okta Developer account (or sign up if you don’t have an account) and navigate to Applications > Add Application.

• Select Web and click Next
• Change the Name to be Quarkus Client
• Change the Login redirect URIs to http://localhost:8080/
• Scroll down and click Done

Put your Okta domain name into src/main/resources/application.properties, along with your client ID and secret.

quarkus.oidc.auth-server-url=https://{yourOktaDomain}/oauth2/default
quarkus.oidc.client-id={yourClientId}
quarkus.oidc.credentials.secret={yourClientSecret}
quarkus.oidc.authentication.scopes=openid,profile
quarkus.oidc.application-type=web-app
quarkus.oidc.authentication.redirect-path=/

NOTE: The value of {yourOktaDomain} should be something like dev-123456.okta.com. Make sure you don't include -admin in the value!

After modifying this file your app will be protected by Okta! See this repo's blog post to learn how to connect this app with a running Kafka server.

This example uses Quarkus's OpenID Connect Adapter to integrate with Okta.
