Does --configfile support json files?

[duyn9uyen]

When starting up Mountebank, I see that mb start has a --configfile option. The documentation mentions a .ejs file. Does "--configfile" accept a JSON-formatted file to load up my imposters? I tried giving it a json file but my imposters did not get loaded.

I am hoping to be able to use the same json (saved as a file), that I would use on this PUT request:

PUT /imposters

I have Mountebank in a container, so on start-up, I would like the container to automatically configure all the imposters I have already set up instead of having to invoke the PUT request manually. Thanks in advance.
