Specify ports to be used

[DhavalThkkar]

Currently I'm trying to use spyder kernels on a docker container. Docker by it's nature requires to specify the ports before using them. Is there any way in which the ports can be predetermined before using the kernel

Hey @DhavalThkkar, thanks for reporting. You can specify your ports using a json file, as described here:
