Hello,
In the next couple of days I plan on getting started on configuring a simple Osmocom based GSM stack with all the key components, to use with a single 1800 MHz Nano BTS.
Before I get too stuck in, I wanted to check if running in Docker (Straight Docker, no kubernetes etc) was feasible, and if the various packages behave when NAT etc is involved?
Thanks Matthew / marrold
See docker-playground.gir for Dockerfiles of all osmocom network elements. It is how our CI works.
However, with all the 3GPP protocols there is none that you can speak through nat or even only with dynamic IPs.
So the only way is to use docker network with static IPs for each container.
Hi Harald,
Thanks for the link, that's very helpful.
I started getting things setup with each component running in a container with a statically assigned container, but I had issues with SCTP between the MSC / BSC and STP (AS_DOWN). I'd see an INIT and INIT ACK, but that was it, and nothing in the STP debug logs. Switching to "Host" networking resolved the issue immediately after updating the IPs in the various .cfgs back to 127.0.0.1. Perhaps it was a config issue or something Docker related - I'm new to the Osmocom GSM stack and SCTP in general so I'm not best suited for troubleshooting this, but as its working with host networking I'll leave as-is
Thanks again Matthew

I’m working through this as well. I got the majority of the stack running using the docker-playground containers in host network mode as long as the Local/NIC IPs were correct in the configs. Still working on getting the ggsn connections right. A docker compose file would be helpful for sure. Matthew, do you have a write up, script or compose file that you could share with the community?

Hi,
If I get it working I'll happily share it, but I'm currently having issues with the BTS so I am unable to test anything.
Thanks
