Hi Aslak I have seen that this method event.getContainer() does not exist in BeforeStart event. The bad news is that at that point I need the Container to get configuration parameters to start a ping to given host and port until container is started inside Docker. Do I have any way to get it?

@Inject
private Instance<ContainerRegistry> registryInst;

public void overrideContainerHostProperty(@Observes BeforeSetup event) {
  Container currentContainer = locateCurrentContainer(event.getDeployableContainer())   
  if(currentContainer == null) {
    throw new RuntimeException("No Container found in registry.. ?");
  }
  currentContainer.getContainerConfiguration().overrideProperty("name", docker2bootIP)
}

private Container locateCurrentContainer(DeployableContainer<?> deployable) {
  for(Container container : registryInst.get().getContainers()) {
    if(container.getDeployableContainer() == deployable) {
      return container;
    }
  }
  return null;
}
