How to create a new realm with Keycloak in Version 20.0.1, REST API and cURL?

In this blog post I want to show, how to create a new realm with Keycloak REST API 20.0.1. The Keycloak API has changed and my older blog post How to create a new realm with the Keycloak REST API? doesn’t work anymore for version 20.0.1. I automate the Keycloak realm creation for an example realm by using cURL in a bash script. First I created the blog post about Export a Keycloak (Version 20) realm and now I show the creation of an example realm in Keycloak. I took a look in the new Keycloak REST API documentation and into the Keycloak Node.js client. In this blog post I use an example realm I exported before, here is the link to the example-realm.

Now we want to access the counter information goobers_total by using the Prometheus HTTP API from a local Golang application.
