Run on a specified port instead of just 3000

[ashokrags]

hi,
This is great and i would like to be able to run either the linux executable or the docker container on a random port instead of port 3000. I do realize that docker could be used for a random port, but I am planning to run this with singularity on a HPC cluster which does not allow for port mapping.
Any thoughts/suggestions will be much appreciated.
Cheers
Ashok

@ashokrags to run the server on a specific port just pass the --port 1234 (0 for a random port) argument to the server.sh script
