Are you looking to streamline the configuration of your Keycloak authentication provider? With the Keycloak Migration project, you can easily automate this task, making it as straightforward as a walk in the park! Inspired by Liquibase, this tool provides a robust solution for migrating your Keycloak instances. In this blog, we’ll guide you through the setup and execution of the Keycloak Migration tool, ensuring that you are well-equipped to enhance your authentication processes.

Getting Started with Keycloak Migration

First things first, you need to ensure that you have the appropriate setup. Follow the outlined steps below to initiate the process efficiently.

1. Install the Plugin

To begin, you’ll need to apply the current version of the Keycloak Migration plugin to your Gradle file. Simply add the following line:

plugins {
    id 'de.klg71.keycloakmigration' version 'x.x.x'
}

2. Execute the Migration

Next, you need to define a task that will execute the migration. Below is a Groovy example:

task keycloakMigrateLocal(type: KeycloakMigrationTask) {
    group = keycloak
    description = 'Migrate the keycloak instance'
    migrationFile = 'migration/keycloak-changelog.yml'
    adminUser = 'admin'
    adminPassword = 'admin'
    baseUrl = 'http://localhost:8080'
    realm = 'master'
    parameters = [USERNAME: 'testUser', PASSWORD: 'testPassword']
    waitForKeycloak = false
    waitForKeycloakTimeout = 0L 
    failOnUndefinedVariables = false
    warnOnUndefinedVariables = true
}

3. Using Kotlin

For those who prefer Kotlin, registration can be done with a similar approach:

registerKeycloakMigrationTask(keycloakMigrateLocal) {
    group = keycloak
    description = 'Migrate the keycloak instance'
    migrationFile = 'migration/keycloak-changelog.yml'
    adminUser = 'admin'
    adminPassword = 'admin'
    baseUrl = 'http://localhost:8080/auth'
    realm = 'master'
    parameters = mapOf(
        USER_NAME to 'testUser',
        PASSWORD to 'password'
    )
    waitForKeycloak = false
    waitForKeycloakTimeout = 0L 
    failOnUndefinedVariables = false
    warnOnUndefinedVariables = true
}

Understanding the Code Through an Analogy

Think of the Keycloak Migration task as a meticulous chef preparing a new dish. Each line of code represents a different ingredient in a recipe:

• The task acts like the chef’s instruction manual, outlining what needs to be done.
• migrationFile is akin to the recipe card displaying the ingredients required for the migration.
• adminUser and adminPassword are like the secret key to the kitchen, allowing the chef (your program) to access all that is needed to create the dish (migrate the instance).
• baseUrl works as the address to the grocery store—the exact location where resources can be found.
• parameters are customized spices tailored to enhance the dish according to your taste.

In a nutshell, each component plays a vital role in ensuring a smooth and successful migration process, much like a well-prepared meal tantalizes its diners!

4. Using the Fat Jar

For those who prefer a simpler method, you can invoke the migration through a jar file. Just execute the following command:

java -jar keycloakmigration.jar --help

Troubleshooting Tips

If you encounter issues while using the Keycloak Migration tool, here are some troubleshooting ideas to guide you:

• Ensure that your baseUrl is properly set and reachable.
• Double-check that your migrationFile path is correct and that the file is structured correctly.
• If your migrations are failing due to undefined variables, try setting failOnUndefinedVariables to true for detailed insights.
• For any persistent issues or further assistance, feel free to reach out for guidance to ensure you’re on the right track.
