Analysis

1. init-container
2. k8s hooks

3. Events in Spring
   
   We can use the ApplicationReadyEvent which is published when the application is ready to service requests.
   We can listen to this event , which is thrown by the SpringApplication itself and then execute some code (which is creating a dataspace in our scenario)
   
   Example
   
   

   Code Block
   language java title ApplicationReadyEvent
   @EventListener(ApplicationReadyEvent.class) public void initializeNcmp() { log.info("Initializing NCMP when the ApplicationReadyEvent is received"); try { cpsAdminService.createDataspace("NCMP-CmHandle-Operational-Data"); } catch (final AlreadyDefinedException ex) { log.info("Already defined : {} ", ex.getMessage()); } catch (final Exception ex) { log.warn("Failed to create dataspace, cause : {}", ex.getMessage()); } }
