Interface ContainerService

All Known Subinterfaces:
HealthStatusProvider, KeyStoreService
public interface ContainerService
The Container is a registry of services, the order of services in a container is important and is determined by the getPriority() value; when starting the Container using the auto service discovery mechanism. If the container is started with an explicit list of services then the insertion order is used.

Service startup lifecycle:

  1. init(org.openremote.model.Container) in registry insertion order
  2. start(org.openremote.model.Container) in registry insertion order

Service shutdown lifecycle:

  1. stop(org.openremote.model.Container) in reverse registry order
