Dev Services for Apicurio Registry
If an extension for schema registry, such as
quarkus-apicurio-registry-avro
or quarkus-confluent-registry-avro
, 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 only applies to serializers and
deserializers from Apicurio Registry serde libraries and Confluent Schema
Registry serde libraries, because there properties are set:
# for Apicurio Registry serde
mp.messaging.connector.smallrye-kafka.apicurio.registry.url=http://localhost:8081/apis/registry/v2
# for Confluent Schema Registry serde
mp.messaging.connector.smallrye-kafka.schema.registry.url=http://localhost:8081/apis/ccompat/v6
Enabling / Disabling Dev Services for Apicurio Registry
Dev Services for Apicurio Registry is automatically enabled unless:
-
quarkus.apicurio-registry.devservices.enabled
is set tofalse
-
mp.messaging.connector.smallrye-kafka.apicurio.registry.url
is configured -
mp.messaging.connector.smallrye-kafka.schema.registry.url
is configured -
all the Reactive Messaging Kafka channels have either the
apicurio.registry.url
attribute or theschema.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. In such case, you can configure the registry URL for all Kafka channels in SmallRye Reactive Messaging with a single property. For Apicurio Registry serde, that is:
mp.messaging.connector.smallrye-kafka.apicurio.registry.url=... your Apicurio Registry URL...
For Confluent Schema Registry serde, that is:
mp.messaging.connector.smallrye-kafka.schema.registry.url=... your Confluent Schema Registry URL...
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:
quarkus.apicurio-registry.devservices.image-name=apicurio/apicurio-registry-mem:latest-snapshot
