Keycloak + postgresql configuration - postgresql

Question

I tried to configure keycloak server with my postgresql db. After many tries with a lot of configs I decided to ask the question.
I have the next configurations:
module.xml which is located in keycloak/modules/org/postgresql/main
Also in that directory I put jdbc-driver with name 'postgresql-42.2.16.jar'
<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="org.postgresql">
<resources>
<resource-root path="postgresql-42.2.16.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
standalone.xml which is located in keycloak/standalone/configuration
In that xml I configured
drivers:
<drivers>
<driver name="postgresql" module="org.postgresql">
<xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
</driver>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
</drivers>
datasources:
<datasources>
<datasource jndi-name="java:jboss/datasources/KeycloakDS" pool-name="KeycloakDS" enabled="true" use-java-context="true">
<connection-url>jdbc:postgres://192.168.99.100:5432/keycloak</connection-url>
<driver>postgresql</driver>
<pool>
<max-pool-size>20</max-pool-size>
</pool>
<security>
<user-name>keycloak</user-name>
<password>password</password>
</security>
</datasource>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true" statistics-enabled="${wildfly.datasources.statistics-enabled:${wildfly.statistics-enabled:false}}">
<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
<driver>h2</driver>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
</datasource>
...
</datasources>
keycloak server config:
<subsystem xmlns="urn:jboss:domain:keycloak-server:1.1">
<spi name="connectionsJpa">
<provider name="default" enabled="true">
<properties>
<property name="dataSource" value="java:jboss/datasources/KeycloakDS"/>
<property name="initializeEmpty" value="false"/>
<property name="migrationStrategy" value="manual"/>
<property name="migrationExport" value="${jboss.home.dir}/keycloak-database-update.sql"/>
</properties>
</provider>
</spi>
</subsystem>
And when I'm trying to start my keycloak server I got the exception:
17:56:19,859 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread)
WFLYCTL0013: Operation ("add") failed - address: ([
("subsystem" => "datasources"),

]) - failure description: {

driver.postgresql]",
"org.wildfly.data-source.KeycloakDS is missing [jboss.jdbc-driver.postgresql]"
]
}

driver.postgresql]",
"org.wildfly.data-source.KeycloakDS is missing [jboss.jdbc-driver.postgresql]",
"org.wildfly.data-source.KeycloakDS is missing [jboss.jdbc-driver.postgresql]"
]
}
It's looks like I configured my datasource in wrong way, but I can't find the error. I checked this check list and it doesn't resolve my issue.

Answer 1

Could you please retry with the following connection string:
jdbc:postgresql://192.168.99.100:5432/keycloak
instead of
jdbc:postgres://192.168.99.100:5432/keycloak
Also, consider letting the SPI/connectionsJpa block at defaults (I believe in particular that initializeEmpty should be true) and I don't remember that I had to add/modify this block, so please double-check.
You may also disable or comment the ExampleDS (h2) dataSource.
