A bit of an odd question I think but here goes: I have a couple of services running in an application that I'm building. In production each service is containerised and lives on its own server. But on my development computer I like to keep local versions all running. Of course, if I have multiple services running on localhost, the only way to do this is to have them each on their own port. Now, to maintain parity between development and production, I figure that I must now also get them all running on those different ports in production.
So I guess my question is is it okay to have all these services running on "non-standard" ports (eg, a webserver that isn't on 80 or 443) in production. My understanding of ports is that: 1) There are some ports usually used for specific services. 2) This isn't mandatory. 3) Some people deliberately change them for security through obscification, but this doesn't achieve much.
So it should be fine? Or is there a better practice for this problem?
