It's not easy and takes a long time to perfect, but our entire VoIP infrastructure is Dockerized, and composed of Asterisk, MySQL, Redis, NodeJS and Kamailio+RTPEngine (not rtpproxy, since rtpproxy isn't maintained anymore). No docker-level port forwarding required anywhere, since the entire system is designed to be volatile (see below).
We have over 500 Asterisk docker containers running, supporting many thousands of users across the world at this point, and it works quite well, so it can be done.
The concept behind the Asterisk containers is designing everything to be completely volatile: Outages happen, even in datacenters, so assume a container will reboot at some point on some random node at some random datacenter location. You don't know Asterisk's private IP, you don't even know where it might pop back up in the cluster. If you can ensure service continuity in that scenario, then you've built a solid setup. Our uptime has been 100% for over 4 years now (this is 3rd-party monitored and validated, in addition to our internal monitoring systems) so I assure you it is very possible.
I also HIGHLY recommend not using a cloud provider for any of the core infrastructure. We tried this, with AWS and GCP, and the voip quality was... meh. The cloud outages were frequent, although customers generally don't notice them when you're using lightweight containers to run everything. So we are fully operating on our own hardware across multiple colo locations, and only using cloud for file storage (eFaxes, voicemails, greetings/recordings, MMS content, phone LCD background images for provisioning, etc).
I am unable to help with your project, but I can at least provide the above pointers/experiences in case they get you in the right direction.
An alternative to building your own infrastructure might be reselling (white label) an existing service provider as well, in case the decision to build your own infrastructure is still up in the air.

I would love to know more about RTPEngine vs RTPProxy. Which of the 2 are
actively maintained? Why would you recommend RTPEngine over the other.
