Ok I see. Thank you very much for the clarification! ^^
I'm going to move the image location to an external volume for the time being.
It looks like the last docker pull command of the previous test ate some space. Could you guys please tell me how I would clean up the remaining cruft? 😬
EDIT:
Reporting back that it was installed successfully after changing the image location to an external volume offering enough disk space.
