What is stopping you from making a project dedicated to orchestration/configuration/deployment and using test containers to make those tests? How do you debug those "complex systems" when they fail? I've made a project in one of my old jobs dedicated to configuration and deployment tools used by CI jobs. At first it got some criticisms about "testing the CI that tests the software" and "testing the tests" but when the number of fires we have to take care of was cut by half it quickly became the norm.
