keycloak-event-listener-http

A Keycloak SPI that publishes events to an HTTP Webhook. A (largely) adaptation of @mhui mhuin/keycloak-event-listener-mqtt SPI. Extended by @darrensapalo to enable building the JAR files from docker images.

Build

Build on your local machine

mvn clean install

Build using docker

Alternatively, you can build the JAR files from a docker image. You must have docker installed.

1. Run make package-image.
2. The JAR files should show up on your mvn-output folder.

If you encounter the following issue:

open {PATH}/mvn-output/event-listener-http-jar-with-dependencies.jar: permission denied

Simply add write permissions to the mvn-output folder:

sudo chown $USER:$USER mvn-output

Deploy

• Copy target/event-listener-http-jar-with-dependencies.jar to {KEYCLOAK_HOME}/standalone/deployments
• Edit standalone.xml to configure the Webhook settings. Find the following section in the configuration:

<subsystem xmlns="urn:jboss:domain:keycloak-server:1.1">
    <web-context>auth</web-context>

And add below:

<spi name="eventsListener">
    <provider name="mqtt" enabled="true">
        <properties>
            <property name="serverUri" value="http://127.0.0.1:8080/webhook"/>
            <property name="username" value="auth_user"/>
            <property name="password" value="auth_password"/>
            <property name="topic" value="my_topic"/>
        </properties>
    </provider>
</spi>

Leave username and password out if the service allows anonymous access. If unset, the default message topic is "keycloak/events".

• Restart the keycloak server.

Use

Add/Update a user, your webhook should be called, looks at the keycloak syslog for debug
