Unwanted exception when a container exits with non-zero status

Hi dudes,

Thank you for this library, it's simply awesome.
I want to ask you a question cause I'm having troubles when trying to get the output from a docker container which, in my use-case, will always return a non-zero status after finishing its execution.
My last try is:

container = clientDocker.containers.run('zricethezav/gitleaks',
                '-v --pretty -r https://github.com/Pitenager/P4-PabloRuiz_MiguelMayoral > scan.txt',
                auto_remove=True,
                )

But it drops the following exception:

Exception has occurred: ContainerError
Command '-v -r https://github.com/Pitenager/P4-PabloRuiz_MiguelMayoral --pretty > scan.txt' in image 'zricethezav/gitleaks' returned non-zero exit status 1

The image i'm trying to run (zricethezav/gitleaks) will always return a non-zero status in my case cause it's the expected case, so how can I manage it?
Also, if there is a better option to save the output of the tool better than > scan.txt I would appreciate your ideas.

Thank you all !

Start by reproducing the clientDocker.containers.run call with the zricethezav/gitleaks image and read how ContainerError handles non-zero exit statuses. Determine whether the library should expose the output without raising or whether the expected behavior needs documentation; done means the non-zero result and output-handling path are clearly established.
