This is a minimal example of an end-to-end srsLTE system running with Docker and shared memory. Core network, base station and user device all run in separate containers. The air interface is emulated via radio samples in shared memory.

See it happen with

docker-compose up

After a while you'll se the UE attach:

virtual-srsue | Network attach successful. IP: 172.16.0.2
virtual-srsenb | User 0x46 connected

Now you can test the connection in a new terminal:

docker exec -i -t virtual-srsepc ping 172.16.0.2
PING 172.16.0.2 (172.16.0.2) 56(84) bytes of data.
64 bytes from 172.16.0.2: icmp_seq=1 ttl=64 time=25.3 ms
64 bytes from 172.16.0.2: icmp_seq=2 ttl=64 time=24.2 ms

Credits go to jgiovatto for implementing the shared memory radio interfaces and to FabianEckermann for figuring out how to integrate it with Docker's IPC functionality.

A note on configuration: During build, the example config files are copied into the workdir. These are the files you see used in the compose file with some option overrides. If you want to play around with the config yourself, it is much easier to place your custom files in this directory and ADD them in the Dockerfile. You can find the exact versions in srsepc, srsenb and srsue.
