===== Securing the Hawtio Administration Console

To secure the Hawtio Administration Console with {{book.project.name}}, complete the following steps:

. Add these properties to the `$FUSE_HOME/etc/system.properties` file:
+
[source]
----
hawtio.keycloakEnabled=true
hawtio.realm=keycloak
hawtio.keycloakClientConfig=${karaf.base}/etc/keycloak-hawtio-client.json
hawtio.rolePrincipalClasses=org.keycloak.adapters.jaas.RolePrincipal,org.apache.karaf.jaas.boot.principal.RolePrincipal
----

. Create a client in the {{book.project.name}} administration console in your realm. For example, in the {{book.project.name}} `demo` realm, create a client `hawtio-client`, specify `public` as the Access Type, and specify a redirect URI pointing to Hawtio: \http://localhost:8181/hawtio/*. You must also have a corresponding Web Origin configured (in this case, \http://localhost:8181).

. Create the `keycloak-hawtio-client.json` file in the `$FUSE_HOME/etc` directory using the similar content as below. Change the `realm`, `resource`, and `auth-server-url` properties according to your {{book.project.name}} environment. The `resource` property must point to the client created in the previous step. This file is used by the client (Hawtio Javascript application) side.
+
[source,json]
----
{
  "realm" : "demo",
  "resource" : "hawtio-client",
  "auth-server-url" : "http://localhost:8080/auth",
  "ssl-required" : "external",
  "public-client" : true
}
----

. Create the `keycloak-hawtio.json` file in the `$FUSE_HOME/etc` dicrectory using similar content as below. Change the `realm` and `auth-server-url` properties according to your {{book.project.name}} environment. This file is used by the adapters on the server (JAAS Login module) side.
+
[source,json]
----
{
  "realm" : "demo",
  "resource" : "jaas",
  "bearer-only" : true,
  "auth-server-url" : "http://localhost:8080/auth",
  "ssl-required" : "external",
  "use-resource-role-mappings": false,
  "principal-attribute": "preferred_username"
}
----

. Start {{book.fuseVersion}} and install the keycloak feature if you have not already. The commands in Karaf terminal are similar to this example:
+
[source, subs="attributes"]
----
features:addurl mvn:org.keycloak/keycloak-osgi-features/{{book.project.versionMvn}}/xml/features
features:install keycloak
----

. Go to http://localhost:8181/hawtio and log in as a user from your {{book.project.name}} realm.
+
Note that the user needs to have the proper realm role to successfully authenticate to Hawtio. The available roles are configured in the `$FUSE_HOME/etc/system.properties` file in `hawtio.roles`.

====== Securing Hawtio on EAP

To run Hawtio on the Wildfly 10 server, complete the following steps:

. Set up {{book.project.name}} as in the Securing the Hawtio Administration Console section above. The following assumptions apply: you have a {{book.project.name}} realm `demo` and client `hawtio-client`, and  your {{book.project.name}} is running on `localhost:8080` while the Wildfly server with deployed Hawtio will be running on `localhost:8181`.

. Copy the `hawtio.war` archive to the `$WILDFLY_HOME/standalone/configuration` directory. For more details about deploying Hawtio see the Fuse Hawtio documentation.

. Copy the `keycloak-hawtio.json` and `keycloak-hawtio-client.json` files with the above content to the `$WILDFLY_HOME/standalone/configuration` directory.

. Install the {{book.project.name}} adapter subsystem to your Wildfly server as described in the <<fake/../../jboss-adapter.adoc#_jboss_adapter,JBoss adapter documentation>>

. In the `$WILDFLY_HOME/standalone/configuration/standalone.xml` file configure the system properties as in this example:
+
[source,xml]
----
<extensions>
...
</extensions>

<system-properties>
    <property name="hawtio.authenticationEnabled" value="true" />
    <property name="hawtio.realm" value="hawtio" />
    <property name="hawtio.roles" value="admin,viewer" />
    <property name="hawtio.rolePrincipalClasses" value="org.keycloak.adapters.jaas.RolePrincipal" />
    <property name="hawtio.keycloakEnabled" value="true" />
    <property name="hawtio.keycloakClientConfig" value="${jboss.server.config.dir}/keycloak-hawtio-client.json" />
    <property name="hawtio.keycloakServerConfig" value="${jboss.server.config.dir}/keycloak-hawtio.json" />
</system-properties>
----

. Add the Hawtio realm to the same file in the `security-domains` section:
+
[source,xml]
----
<security-domain name="hawtio" cache-type="default">
    <authentication>
        <login-module code="org.keycloak.adapters.jaas.BearerTokenLoginModule" flag="required">
            <module-option name="keycloak-config-file" value="${hawtio.keycloakServerConfig}"/>
        </login-module>
    </authentication>
</security-domain>
----

. Add the `secure-deployment` section `hawtio` to the adapter subsystem. This ensures that the Hawtio WAR is able to find the JAAS login module classes.

+
[source,xml]
----
<subsystem xmlns="urn:jboss:domain:keycloak:1.1">
    <secure-deployment name="hawtio.war" />
</subsystem>
----

. Restart the Wildfly server with Hawtio:
+
[source,xml]
----
cd $WILDFLY_HOME/bin
./standalone.sh -Djboss.socket.binding.port-offset=101
----

. Access Hawtio at http://localhost:8181/hawtio. It is secured by {{book.project.name}}.
