Quarkus Dev Services and Testing

Check the project's Quarkus version first. Framework-neutral Testcontainers usage can use the optional java-testcontainers skill if installed (otherwise see https://java.testcontainers.org/); this skill covers only Quarkus-specific features.

Dev Services

In dev and test modes Quarkus starts containers (PostgreSQL, MySQL, Kafka, Redis, Keycloak, ...) automatically when the related extension is present and no connection is configured (Docker or Podman required).

# Global switch
quarkus.devservices.enabled=true
%dev.quarkus.datasource.devservices.image-name=postgres:17
# Reuse container across restarts (also requires testcontainers.reuse.enable=true in ~/.testcontainers.properties)
quarkus.datasource.devservices.reuse=true
# Fixed port (optional)
quarkus.datasource.devservices.port=5432
# Share between apps in dev mode
quarkus.kafka.devservices.shared=true
