+Whether dev services containers shall be reused across restarts.  <br/><br/>  When enabled, containers are kept running when Dependency-Track stops, and  re-attached to on the next start. This preserves PostgreSQL state (schema and data)  across restarts and avoids the cost of re-provisioning on every run.  <br/><br/>  This additionally requires Testcontainers reuse to be opted into on the  developer's machine, either via testcontainers.reuse.enable=true in the  `~/.testcontainers.properties` file, or the `TESTCONTAINERS_REUSE_ENABLE=true`  environment variable. Without it, this option has no effect and containers  are disposed on shutdown as usual.  See <https://java.testcontainers.org/features/reuse/#how-to-use-it>.

-Whether dev services shall be enabled.  <br/><br/>  When enabled, Dependency-Track will automatically launch containers for:  <ul>  <li>Frontend</li>  <li>PostgreSQL</li>  </ul>  at startup, and configures itself to use them. They are disposed when  Dependency-Track stops. The containers are exposed on randomized ports,  which will be logged during startup.  <br/><br/>  Trying to enable dev services in a production build will prevent  the application from starting.  <br/><br/>  Note that the containers launched by the API server can not currently  be discovered and re-used by other Hyades services. This is a future  enhancement tracked in <https://github.com/DependencyTrack/hyades/issues/1188>.

They are disposed when  Dependency-Track stops.  <br/><br/>  The port on which the frontend will be exposed is configurable via  [`dt.dev-services.frontend-port`](#dtdev-servicesfrontend-port). The port of the postgres container  is automatically inferred from dt.datasource.default.url.  <br/><br/>  Trying to enable dev services in a production build will prevent  the application from starting.
