Labs can't start if the docker image used is too big

[Alessandro Placido Luise]

Describe the bug
Labs can't start if the docker image used is too big.

To Reproduce
Steps to reproduce the behavior:
1 - Create a new lab.
2 - Drag a host in the GUI.
3 - Select an image of size greater than 1GB

Log
On running lab :

ERROR: DockerSecurityPlayground/2413 on kali: Trying to redefine maintainer which is a string

Notes
"maintainer" is a label in this tested docker image used to reproduce the bug. If I remove maintainer it gives the same problem with "CMD".
