Usage

You can use Docker Compose to run the necessary backing services for observability, authentication, and AI.

From the project root folder, run Docker Compose.

docker-compose up -d

The Instrument Service application can be run as follows to rely on Testcontainers to spin up a PostgreSQL database:

./gradlew bootTestRun

The Edge Service application can be run as follows:

./gradlew bootRun

The Chat Service application can be run using one of the two techniques described above. If you don't want to rely on Testcontainers, make sure you have Ollama installed and the Llama2 model available (ollama run llama2).

Two tenants are configured: dukes and beans. Ensure you add the following configuration to your hosts file to resolve tenants from DNS names.

127.0.0.1       dukes.rock
127.0.0.1       beans.rock

Now open the browser window and navigate to http://dukes.rock/instruments/. You'll be redirected to the Keycloak authentication page. Log in with isabelle/password. The result will be the list of instruments from the Dukes rock band.

Now open another browser window and navigate to http://beans.rock/instruments/. You'll be redirected to the Keycloak authentication page. Log in with bjorn/password. The result will be the list of instruments from the Beans rock band.
