Creating a Testing Keycloak

The Docker Compose setup in this directory sets up Keycloak and imports a realm testing.

Starting Keycloak

Run docker compose up -d to start Keycloak. The admin console will be available at http://localhost:8080/.

You can attach a Java debugger at localhost:8081.

The realm export is in import/testing.json. It will be imported automatically when Keycloak starts.

Updating the Realm

If you want to make changes to the testing realm and persist them, you need to export the realm.

The following command runs the Keycloak export for the realm testing storing it in the mapped directory import/testing.json. The copying of the database is necessary to avoid locking errors. env -i makes sure the regular environment variables are not set to avoid port conflicts.

docker compose exec -it keycloak sh -c "cp -rp /opt/keycloak/data/h2 /tmp && env -i -- /opt/keycloak/bin/kc.sh export --db dev-file --db-url 'jdbc:h2:file:/tmp/h2/keycloakdb;NON_KEYWORDS=VALUE' --file /opt/keycloak/data/import/testing.json --realm testing"
