java.lang.Object
com.ammann.servicemanager.service.ContainerMonitorService
@ApplicationScoped public class ContainerMonitorService extends Object
Scheduled background service that monitors Docker containers.

Performs two periodic tasks:

  • Checks for available image updates for remote containers (every 5 minutes).
  • Verifies that all containers are in the "running" state (every 30 seconds).

Local images (those without a registry prefix) are excluded from update checks because they cannot be pulled from a remote registry.
