Dev Services for Kogito

If any Kogito process-related extension is present (e.g. kogito-quarkus or kogito-quarkus-processes), Dev Services for Kogito automatically starts a Data Index in dev mode. So, you don’t have to start it manually or have any other service set-up manually. The application is configured automatically, meaning that will replicate any Kogito messaging events related to Process Instances and User Tasks into the provisioned Data Index instance.

Additionally, Dev UI available at /q/dev complements this feature with a Dev UI page which helps to Query Data Index via its GraphiQL UI.

For more details about how to query data about processes and user tasks, please visit Kogito Data Index documentation.

Enabling / Disabling Dev Services for Kogito

Dev Services for Kogito is automatically enabled unless:

  • quarkus.kogito.devservices.enabled is set to false

Dev Services for Kogito relies on Docker to start the broker. If your environment does not support Docker, you will need to start the broker manually, or connect to an already running Data Index.

Shared Data Index

In case you would like to share the Data Index instance between applications. Dev Services for Kogito implements a service discovery mechanism for your multiple Quarkus applications running in dev mode to share a single instance.

Note
 Dev Services for Kogito starts the container with the kogito-dev-service-data-index label which is used to identify the container.

If you need multiple (shared) Data Index instances, you can configure the quarkus.kogito.devservices.service-name attribute and indicate the instance name. It looks for a container with the same value, or starts a new one if none can be found. The default service name is kogito-data-index.

Sharing is enabled by default in dev mode. You can disable the sharing with quarkus.kogito.devservices.shared=false.

Setting the port

By default, Dev Services for Kogito starts a Data Index using port 8180. You can set the port by configuring the quarkus.kogito.devservices.port property.

Configuring the image

Dev Services for Kogito uses: kiegroup/kogito-data-index-ephemeral images. You can select any version from https://quay.io/repository/kiegroup/kogito-data-index-ephemeral?tab=tags.
