Unable to configure postgreSQL datasource for Keycloak - postgresql

Question

I'm trying to configure a PostgresSQL datasource by following the
tutorial presented in the documentation:
http://www.keycloak.org/docs/1.9/server_installation_guide/topics/database.html
.
I'm doing the configuration for a standalone server by running
standalone.bat and by configuring everything in
keycloak-3.0.0.Final/standalone/configuration/standalone.xml .
I'm following the documentation step-by-step, but I get the following
error running standalone.bat every-time, and thus I'm unable to connect to the database.
15:33:11,684 ERROR [org.jboss.as.controller.management-operation]

I have tried different versions of JDBC drivers provided by:
https://jdbc.postgresql.org/, but to no avail, even by
using the version mentioned in the documentation.
At this point I am stuck since my configuration files look exactly like
in the documentation. What exactly could I be missing? Is the
documentation up to date?
you cant find the same question- http://lists.jboss.org/pipermail/keycloak-user/2017-March/010120.html,
but couldnt find any solution there,so re posting the same here.

Answer 1

I use jboss-cli.sh (or .bat if you're on Windows) to manage this for me. With Keycloak stopped and your PATH including $KEYCLOAK_HOME/bin I put the script below into a file (example: config_db.cli):
embed-server --server-config=standalone.xml --std-out=echo
batch
#
# remove the default provided datasource
#
/subsystem=datasources/data-source=KeycloakDS/:remove
#
# add it back using PostgreSQL
#
module add --name=org.postgres --resources=/path/to/your/postgresql-42.1.4.jar --dependencies=javax.api,javax.transaction.api
/subsystem=datasources/jdbc-driver=postgres:add(driver-name="postgres",driver-module-name="org.postgres",driver-class-name=org.postgresql.Driver)
/subsystem=datasources/data-source=KeycloakDS/:add(connection-url=jdbc:postgresql://localhost:5432/db_name,driver-name=postgres,jndi-name=java:jboss/datasources/KeycloakDS,password=db_password,user-name=db_user)
run-batch
And run with bin/jboss-cli.sh --file=config_db.cli
Note that this assumes you've already created a PostgreSQL database user (db_user above) with a password (db_password) and a database owned by the db_user (db_name).
In this way I can create my datasources the same way on my local machine as I do on my servers.
CORRECTIONS MADE: The format for running the jboss-cl.sh is:
bin/jboss-cli.sh --file=filename
