# keycloak-nats

A Keycloak event listener which publishes events to NATS or NATS Streaming (STAN)

## Inspiration

The layout of this project is inspired
by [aznamier/keycloak-event-listener-rabbitmq](https://github.com/aznamier/keycloak-event-listener-rabbitmq).

## Installation

1. Download the source code (for example via Git)
2. Build the project (`./gradlew shadowJar`)
3. Move the built jar (located in `build/libs` and ends with `-all.jar`) into
   the `$KEYCLOAK_HOME/standalone/deployments` directory
4. Keycloak supports hot reload, however, you **may** need to restart it
5. Log into the admin console, select the realm you want to enable NATS event adapting for, head over to 'Events >
   Config' and add `keycloak-nats-adapter` to the list of active event listeners

## Configuration

Configuration is done via environment variables. I read something about some included XML configuration solution and
decided not to use it because we don't live in the stone age anymore.

| Environment Variable      | Data Type | Description                                                        | Default Value           |
|---------------------------|-----------|--------------------------------------------------------------------|-------------------------|
| `KEYCLOAK_NATS_JETSTREAM` | boolean   | Whether or not to use NATS JetStream; plain NATS is used otherwise | `false`                 |
| `KEYCLOAK_NATS_URL`       | string    | The NATS URL to connect to; may contain authentication details     | `nats://localhost:4222` |
| `JETSTREAM_ADMIN_SIZE`    | string    | Admin stream size when JetStream is used                           | `1 MB`                  |
| `JETSTREAM_CLIENT_SIZE`   | string    | Client stream size when JetStream is used                          | `1 MB`                  |

## Channel Name / Subject

The channel name or subject structure depends on the event type:

* **Admin Event:** `keycloak.event.admin.<realm>.<success/error>.<resourceType>.<operation>` (for
  example `keycloak.event.admin.master.success.user.update`)
* **Client Event:** `keycloak.event.client.<realm>.<success/error>.<clientId>.<type>` (for
  example `keycloak.event.client.master.success.security-admin-console.refresh_token`)

The `resourceType`, `operation` and `type` parts are **always forced to be lowercase** even though Keycloak fires them
in an uppercase format.

Spaces get replaced with underscores.

## Representation Examples
