Stage 3 - Docker compose setup

Q/A
#1

Hi, I am using your project for a university project and I am trying to bring the newly released stage 3 docker compose stack up and running.
Sadly I have some issues and I am not sure what it causing it and how to solve it.
I followed the configuration from this repo https://github.com/free5gc/free5gc-compose.
But at the point ‘run up’ I was not quite sure what to choose, because this repo that is written and getting build there looks like the stage 2 module.
Anyway I tried to do just docker-compose up in the main repository and had issues with the UPF services. The first error I see is this one:

GtpLinkCreate() GTP device named upfgtp0: Create fail
GtpDEvListCreate() GTPv1 tunnel create fail: IP[10.200.200.101]

Any idea how to solve this ?
And I already tried the troubleshooting but it didn’t helped.

Hi,
Did you insert the gtp5g module as describes on the pre-request part ?
If not most of the time it will show “GTP device create fail”, because the gtp5g module is not inserted into the kernel.

Each time the OS is restarted, you need to manually load the module into the kernel
1、modprobe udp_tunnel
2、insmod gtp5g

You could change to the automatic loading method.

Thanks! I was not aware that I have to include the kernel module at every boot in the vm.
