Docker0 is down even if container is running

I’m using a kali linux VM on virtualbox, with a bridged type connection. The problem is that im using a docker container to do a penetration test on an API but my docker0 interface is down and i can’t find a way to put it up. Is it normal or I am missing something? I have already tried many commands but none work. Feel free to ask me anything more if needed, Thank you
