Dev Services for Apicurio Registry

If the quarkus-apicurio-registry-avro extension is present, Dev Services for Apicurio Registry automatically starts an Apicurio Registry instance in dev mode and when running tests. Also, all Kafka channels in SmallRye Reactive Messaging are automatically configured to use this registry. (This automatic configuration of course only applies to serializers and deserializers from the Apicurio Registry Avro library.)

Enabling / Disabling Dev Services for Apicurio Registry

Dev Services for Apicurio Registry is automatically enabled unless:

  • quarkus.apicurio-registry.devservices.enabled is set to false

  • mp.messaging.connector.smallrye-kafka.apicurio.registry.url is configured

  • all the Reactive Messaging Kafka channels have the apicurio.registry.url attribute set

Dev Services for Apicurio Registry relies on Docker to start the registry. If your environment does not support Docker, you will need to start the registry manually, or use an already running registry. You can configure the registry URL for all Kafka channels in SmallRye Reactive Messaging with a single property:

mp.messaging.connector.smallrye-kafka.apicurio.registry.url=http://localhost:8081/apis/registry/v2

Shared registry

Most of the time you need to share the registry between applications. Dev Services for Apicurio Registry implements a service discovery mechanism for your multiple Quarkus applications running in dev mode to share a single registry.

Dev Services for Apicurio Registry starts the container with the quarkus-dev-service-apicurio-registry label which is used to identify the container.

If you need multiple (shared) registries, you can configure the quarkus.apicurio-registry.devservices.service-name attribute and indicate the registry 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 apicurio-registry.

Sharing is enabled by default in dev mode, but disabled in test mode. You can disable the sharing with quarkus.apicurio-registry.devservices.shared=false.

Setting the port

By default, Dev Services for Apicurio Registry picks a random port and configures the application. You can set the port by configuring the quarkus.apicurio-registry.devservices.port property.

Note that the Kafka channels in SmallRye Reactive messaging are automatically configured with the chosen port.

Configuring the image

Dev Services for Apicurio Registry uses apicurio/apicurio-registry-mem images. You can select any 2.x version from https://hub.docker.com/r/apicurio/apicurio-registry-mem:
