# Set up an existing Keycloak IAM server

Set up an existing Keycloak IAM server to use with Pentaho Data Mastering if you do not want to install the default Keycloak IAM server.

Complete the following steps to configure the Docker container to use an existing Keycloak IAM server:

1. Open a file transfer tool, like the PuTTY client, and log into the server.
2. Run the following command with the environmental variables specified for the Keycloak server IP and Keycloak server secret:

   ```
   $ sudo truncate -s 0 /opt/mdm/conf/.keycloak.env > /dev/null

   $ echo "KEYCLOAK_REALM=mdm" |sudo tee -a /opt/mdm/conf/.keycloak.env> /dev/null
   $ echo "KEYCLOAK_ID=mdm" |sudo tee -a /opt/mdm/conf/.keycloak.env > /dev/null
   $ echo "KEYCLOAK_HOST=http://<Keycloak_server_ip>:8080   " |sudo tee -a /opt/mdm/conf/.keycloak.env > /dev/null
   $ echo "KEYCLOAK_SECRET= <Keycloak_server_secret> " |sudo tee -a /opt/mdm/conf/.keycloak.env > /dev/null
   ```

After you have set up the Keycloak IAM server, see [Installing the Pentaho Data Mastering server](broken://pages/z6uDqSK6XVabbM8nopgW).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pentaho-data-mastering/installing-pentaho-data-mastering/setting-up-the-keycloak-iam-server/set-up-an-existing-keycloak-iam-server.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
