I like the OWASP Top Ten for “developers” charts. From my point of view, it gives an awesome advice, where to start or helps to take care and remember what you maybe already know about web security implementation. From my side it feels a bit like “rub salt into the wound” of a developer soul, isn’t it so? Especially when you starting developing cloud native and microservices based applications.

In this blog post I want to show, how to create a new realm with Keycloak REST API , because later I want to automate the Keycloak realm creation for a workshop using curl in a bash script.
The reason of that blog post is, that the information in the REST API documentation wasn’t detailed enough for me. The image shows what I found first in the Keycloak REST API documentation .
In common it’s very simple to use the Keycloak REST API. For more details see in my blog post Getting started to secure a simple Java Microservice with Keycloak, MicroProfile and OpenLiberty.
First you need a bearer authorization token for an administration user and with that token you create a new realm using the realm json exported before.
Here is what I found:
I used POSTMAN to check it out. These are the steps I did in POSTMAN.
In that project I want to …
… secure the Microservice with Authentication
… secure a specific REST Endpoint invocation of the Microservice Authorization
… test the access to the Microservice with a JUnit test.
The Microservice runs on OpenLiberty and uses MicroProfile. The example Microservice is called Authors and is from the open sourced Cloud Native Starter project. So, you can compare the implementation of the Authors Microservice in this project with the implementation in the Cloud Native Starter project. The example doesn’t use a frontend UI for the Authentication. The JUnit test will authenticate with the Keycloak REST API.
Here is a 7 min YouTube video about the setup of the example:
The objective of this blog post is to share with you an extract of a “simple” example project on GitHub I created to get started with: How to access a Java Microservice using the Open Source Identity and Access Management with Keycloak and JavaWebToken (JWT).
