According with this

orchestrator/src/orchestrator/core/startup.py

Lines 126 to 135 in cb7e2e1

	# Perseo: optional
	PERSEO_HOST = settings.PERSEO['host']
	PERSEO_PORT = settings.PERSEO['port']
	PERSEO_PROTOCOL = settings.PERSEO['protocol']
	orion = PerseoOperations(PERSEO_PROTOCOL, PERSEO_HOST, PERSEO_PORT)
	try:
	orion.checkPERSEO()
	logger.info("PERSEO endpoint OK")
	except Exception as ex:
	logger.warn("PERSEO endpoint not found: %s" % ex)

if perseo is not ready just a warn log about that is repoted, but orchestrator starts
