There are many "createContainer" methods which are very similar.
Are they different by thoughtful design or it just happened?
Would there be a benefit by refactoring them to one?
To what extent is Is it possible to to reuse running containers in order to speed up testing?
As most tests modify environment variables before starting the container its seems not possible to a great extent
but in TestBasic the same container is now used 5 times, which would be an decrease in test-time by ca 2 minutes in the pipeline. (Startup time of a container is usually 25-30 sec)
