Test with various databases

MySQL

The simplest way to test with MySQL is to use the official MySQL docker image.

Start MySQL:

docker run --name mysql -e MYSQL_DATABASE=keycloak -e MYSQL_USER=keycloak -e MYSQL_PASSWORD=keycloak -e MYSQL_ROOT_PASSWORD=keycloak -d mysql

Run tests:

mvn install -Dkeycloak.connectionsJpa.url=jdbc:mysql://`docker inspect --format '{{ .NetworkSettings.IPAddress }}' mysql`/keycloak -Dkeycloak.connectionsJpa.driver=com.mysql.jdbc.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak    

Stop MySQl:

docker rm -f mysql

PostgreSQL

The simplest way to test with PostgreSQL is to use the official PostgreSQL docker image.

Start PostgreSQL:

docker run --name postgres -e POSTGRES_DATABASE=keycloak -e POSTGRES_USER=keycloak -e POSTGRES_PASSWORD=keycloak -e POSTGRES_ROOT_PASSWORD=keycloak -d postgres

Run tests:

mvn install -Dkeycloak.connectionsJpa.url=jdbc:postgresql://`docker inspect --format '{{ .NetworkSettings.IPAddress }}' postgres`:5432/keycloak -Dkeycloak.connectionsJpa.driver=org.postgresql.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak    

Stop PostgreSQL:

docker rm -f postgres

MariaDB

The simplest way to test with MariaDB is to use the official MariaDB docker image.

Start MariaDB:

docker run --name mariadb -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=keycloak -e MYSQL_USER=keycloak -e MYSQL_PASSWORD=keycloak -d mariadb:10.1

Run tests:

mvn install -Dkeycloak.connectionsJpa.url=jdbc:mariadb://`docker inspect --format '{{ .NetworkSettings.IPAddress }}' mariadb`/keycloak -Dkeycloak.connectionsJpa.driver=org.mariadb.jdbc.Driver -Dkeycloak.connectionsJpa.user=keycloak -Dkeycloak.connectionsJpa.password=keycloak    

Stop MySQl:

docker rm -f mariadb

Using built-in profiles to run database tests using docker containers

The project provides specific profiles to run database tests using containers. The supported databases and their respective profiles are:

• db-mysql
• db-postgres
• db-mariadb
• db-mssql2017
• db-oracle11g

As an example, to run tests using a MySQL docker container on Undertow auth-server:

mvn -f testsuite/integration-arquillian clean verify -Pdb-mysql

If you want to run tests using a pre-configured Keycloak distribution (instead of Undertow):

mvn -f testsuite/integration-arquillian clean verify -Pdb-mysql,jpa,auth-server-wildfly

Note that you must always activate the jpa profile when using auth-server-wildfly.

If the mvn command fails for any reason, it may also fail to remove the container which must be then removed manually.

For Oracle databases, neither JDBC driver nor the image are publicly available due to licensing restrictions and require preparation of the environment. You first need to download the JDBC driver and install it to your local maven repo (feel free to specify GAV and file according to the one you would download):

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0 -Dpackaging=jar -Dfile=ojdbc7.jar -DgeneratePom=true

Then build the Docker image per instructions at https://github.com/oracle/docker-images/tree/master/OracleDatabase. The last step is running which might require updating the jdbc.mvn.groupId, jdbc.mvn.artifactId, and jdbc.mvn.version according to the parameters you used in the command above, and docker.database.image if you used a different name or tag for the image.

Note that Docker containers may occupy some space even after termination, and especially with databases that might be easily a gigabyte. It is thus advisable to run docker system prune occasionally to reclaim that space.
