It worked if I run them on same docker image.

jwijenbergh commented 3 years ago

Hello,

I am using the following docker-compose file on srsLTE 20.10.1 with zeromq: https://github.com/jwijenbergh/srslte-docker-emulated/blob/master/docker-compose.yml

Do note that the Dockerfile points to my current fork (see https://github.com/jwijenbergh/srslte-docker-emulated/blob/513d62a1c5421ea3b61c4141d0e8c6d9da5854ab/Dockerfile#L32) so you might need to change this. Hope this helps

ShubhamTatvamasi commented 3 years ago

But I am not able to ping the IP

jwijenbergh commented 3 years ago

Do you not have the core network (srsepc) in the docker-compose file? Pinging the UE ip can be done with docker exec -i -t virtual-srsepc ping 172.16.0.2. Also see https://github.com/jwijenbergh/srslte-docker-emulated/blob/master/start.sh

ShubhamTatvamasi commented 3 years ago

I don't have srsepc, I am using Magma as my Core Network. Updating my code on this repo: https://github.com/ShubhamTatvamasi/srsRAN-demo

jwijenbergh commented 3 years ago

Okay. Are you running magma outside of docker? I think the best would be to have everything in docker, that way you can use a docker network to connect the components.

ShubhamTatvamasi commented 3 years ago

Magma's Access Gateway is on VirtualBox. I am able to ping Access Gateway's using VirtualBox IP. Like this:

docker exec -it srsue ping 192.168.129.1

But the new Attached UE IP is inside container. How to access that?

ShubhamTatvamasi commented 3 years ago

So I switched the network to host and it's working now. Thanks for your help @jwijenbergh :)

jwijenbergh commented 3 years ago

No problem @ShubhamTatvamasi. Switching to network host is indeed a good idea if not everything is inside the docker compose file. Good that it works now!

ping2balaji commented 3 years ago

Hi @ShubhamTatvamasi , i am looking to test magma LTE-Core with srsran ue/enb simulation. Could you pls provide some insights on the same? i saw your branch on this demo. Just like to know where to punch-in mme-ip/gtp-ip in srsran to successfully test a simple attach/detach call. Any help highly appreciated.

You can update that here: https://github.com/ShubhamTatvamasi/srsRAN-demo/blob/master/docker-compose.yaml

@Shubham can you please describe what it means as Switch the network to host?
