Dev Services Overview
Quarkus supports the automatic provisioning of unconfigured services in development and test mode. We refer to this capability as Dev Services. From a developer’s perspective this means that if you include an extension and don’t configure it then Quarkus will automatically start the relevant service (usually using Testcontainers behind the scenes) and wire up your application to use this service.
All this functionality is part of the Quarkus deployment modules, so does not affect the production application in any
way. If you want to disable all Dev Services you can use the quarkus.devservices.enabled=false config property, although
in most cases this is not necessary as simply configuring the service will result in the Dev Service being disabled automatically.
Note that the default startup timeout is 60s, if this is not enough you can increase it with the quarkus.devservices.timeout property.
This page lists all the Dev Services that Quarkus supports.
| In order to use Dev Services you will generally need a working Docker environment (remote environments are supported). If you don’t have Docker installed you will need to configure your services normally. |
AMQP
The AMQP Dev Service will be enabled when the quarkus-smallrye-reactive-messaging-amqp extension is present in your application, and
the broker address has not been explicitly configured. More information can be found at the
AMQP Dev Services Guide.

Apicurio Registry
The Apicurio Dev Service will be enabled when the quarkus-apicurio-registry-avro extension is present in your application, and it’s
address has not been explicitly configured. More information can be found at the
Apicurio Registry Dev Services Guide.

Databases
The database Dev Services will be enabled when a reactive or JDBC datasource extension is present in the application, and the database URL has not been configured. More information can be found at the Databases Dev Services Guide.
Quarkus provides Dev Services for all databases it supports. Most of these are run in a container, except H2 and Derby which are run in-process. Dev Services are supported for both JDBC and reactive drivers.
Those relational databases that are running in a container are started using Testcontainers and support "reusable instances";
this implies that if you add the property testcontainers.reuse.enable=true in your Testcontainers configuration file,
a property file named .testcontainers.properties in your user home, then the databases will not be stopped aggressively
after each run, and can be reused.
N.B. if you opt in for this feature, Quarkus will not reset the state of the database between runs unless you explicitly configure it to.
