Dev Services for Elasticsearch
If any Elasticsearch-related extension is present (e.g. quarkus-elasticsearch-rest-client or quarkus-hibernate-search-orm-elasticsearch),
Dev Services for Elasticsearch automatically starts an Elasticsearch server in dev mode and when running tests.
So, you don’t have to start a server manually.
The application is configured automatically.
Enabling / Disabling Dev Services for Elasticsearch
Dev Services for Elasticsearch is automatically enabled unless:
-
quarkus.devservices.enabledis set tofalse. -
quarkus.elasticsearch.devservices.enabledis set tofalse -
the hosts property is configured, depending on the extension used it can be:
-
quarkus.elasticsearch.hosts -
quarkus.hibernate-search-orm.elasticsearch.hosts
Dev Services for Elasticsearch relies on Docker to start the server. If your environment does not support Docker, you will need to start the server manually, or connect to an already running server.
Shared Elasticsearch
Sometimes you need to share the server between applications. Dev Services for Elasticsearch implements a service discovery mechanism for your multiple Quarkus applications running in dev mode to share a single server.
Dev Services for Elasticsearch starts the container with the quarkus-dev-service-elasticsearch label which is used to identify the container.
|
If you need multiple (shared) servers, you can configure the quarkus.elasticsearch.devservices.service-name attribute and indicate the server 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 elasticsearch.
Sharing is enabled by default in dev mode, but disabled in test mode.
You can disable the sharing with quarkus.elasticsearch.devservices.shared=false.
Definindo a porta
By default, Dev Services for Elasticsearch picks a random port and configures the application.
You can set the port by configuring the quarkus.elasticsearch.devservices.port property.
Note that the Elasticsearch hosts property is automatically configured with the chosen port.
Configurando a imagem
Dev Services for Elasticsearch support distributions based on both Elasticsearch and OpenSearch images.
When using Hibernate Search, Dev Services will default to Elasticsearch or OpenSearch based on Hibernate Search configuration.
Otherwise, Dev Services will default to Elasticsearch. To use OpenSearch, configure the distribution explicitly:
quarkus.elasticsearch.devservices.distribution=opensearchIf you need to use a different Elasticsearch or OpenSearch image than the default one you can configure it via:
quarkus.elasticsearch.devservices.image-name=docker.io/elastic/elasticsearch:8.15.0For exotic image names, Quarkus might be unable to infer the distribution (elastic or opensearch).
In these cases starting the Dev Services will fail, and you will need to configure the distribution explicitly:
quarkus.elasticsearch.devservices.image-name=my-custom-image-with-no-clue-about-the-distribution:1.0
quarkus.elasticsearch.devservices.distribution=elasticsearchReusing Dev Services
General case
Within a dev mode session or test suite execution, Quarkus will always reuse Elasticsearch Dev Services as long as their configuration (username, password, environment, port bindings, …) did not change.
When the configuration of Elasticsearch Dev Services changes, Quarkus will always restart the corresponding containers.
When a dev mode session or test suite execution ends, Quarkus will (by default) stop Elasticsearch Dev Services.
Reusing Dev Service containers across runs
If you want to keep Dev Service containers running after a dev mode session or test suite execution
to reuse them in the next dev mode session or test suite execution,
this is possible as well.
Just enable TestContainers reuse
by inserting this line in one of your
TestContainers configuration file
(generally ~/.testcontainers.properties or C:/Users/myuser/.testcontainers.properties):
testcontainers.reuse.enable=true|
Even with container reuse enabled, containers will only be reused if their startup command did not change: same environment variables (username/password in particular), same port bindings, … |
|
Reusing containers implies reusing their internal state, including the Elasticsearch schema and the content of indexes. If that’s not what you want — and if your tests write to the indexes, that’s probably not what you want — consider reinitializing your schema and data on application startup. If you use Hibernate Search, Hibernate Search’s schema management may help with that. |
|
With container reuse enabled, old containers (especially with obsolete configuration) might be left running indefinitely, even after starting a new Quarkus dev mode session or test suite execution. In that case, you will need to stop and remove these containers manually. |
If you want to reuse containers for some Quarkus applications but not all of them,
or some Dev Services but not all of them,
you can disable this feature for a specific Dev Service by setting the configuration property
quarkus.elasticsearch.devservices.reuse
to false.
Current limitations
Currently, only the default backend for Hibernate Search Elasticsearch is supported, because Dev Services for Elasticsearch can only start one Elasticsearch container.
