OpenID Connect - OpenTofu setup

OpenTofu is an open-source IaC (Infrastructure as Code) tool, forked from Terraform.

This guide will show how to automatically create the OpenID client on common OpenID Connect providers.

It will use OpenTofu but should also work with Terraform.

IMPORTANT

This example assumes you have your OpenID Connect provider up and running.

You also need to have OpenTofu properly setup, you can follow the official guide.

Keycloak

Keycloak provides an official OpenTofu/Terraform provider:

• https://registry.terraform.io/providers/keycloak/keycloak/latest/docs
• https://search.opentofu.org/provider/keycloak/keycloak/latest

You can follow official instructions to properly connect OpenTofu to Keycloak:

oktomusic.tf

terraform {
  required_providers {
    keycloak = {
      source = "keycloak/keycloak"
      version = "5.7.0"
    }
  }
}

provider "keycloak" {
  # Authentication options
}
