Examples with ZeebeVolume io.zeebe.containers.ZeebeVolume used on opensource projects

Example 1 with ZeebeVolume

use of io.zeebe.containers.ZeebeVolume in project zeebe-test-container by camunda-community-hub.

the class RestartWithExtractedDataExampleTest method shouldGenerateData.

/**
 * Start a container with a volume, deploy a process, and extract the generated data to some
 * folder. In the next test, we will reuse this data to create a process instance, proving that
 * the data was successfully reused.
 *
 * <p>NOTE: since Zeebe is an asynchronous system, and we cannot guarantee when the engine is
 * idle, we stop the container before extracting the data. This causes us to start a second
 * (albeit tiny) container to extract the data.
 *
 * <p>If you all you wanted was to extract data from a live container, then you can use the {@link
 * ContainerArchive#builder()} directly and pass in your live container. For such a use case, you
 * wouldn't even need to be using a volume.
