1. Retrieving the images on Docker-Hub
Currently the images are hosted under the user account rdefosseoai.
This may change in the future.
Once again you may need to log on docker-hub if your organization has reached pulling limit as anonymous.
$ docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username:
Password:
Now pull images.
$ docker pull mysql:5.7
$ docker pull rdefosseoai/oai-amf:latest
$ docker pull rdefosseoai/oai-nrf:latest
$ docker pull rdefosseoai/oai-smf:latest
$ docker pull rdefosseoai/oai-spgwu-tiny:latest
$ docker pull rdefosseoai/oai-gnb:develop
$ docker pull rdefosseoai/oai-nr-ue:develop
And re-tag them for tutorials' docker-compose file to work.
$ docker image tag rdefosseoai/oai-amf:latest oai-amf:latest
$ docker image tag rdefosseoai/oai-nrf:latest oai-nrf:latest
$ docker image tag rdefosseoai/oai-smf:latest oai-smf:latest

$ docker image tag rdefosseoai/oai-nr-ue:develop oai-nr-ue:develop
$ docker logout
2. Deploy containers
CAUTION: this SHALL be done in multiple steps.
Just docker-compose up -d WILL NOT WORK!
All the following commands SHALL be run from the ci-scripts/yaml_files/5g_rfsimulator folder.
2.1. Deploy OAI 5G Core Network
$ cd ci-scripts/yaml_files/5g_rfsimulator
$ docker-compose up -d mysql oai-nrf oai-amf oai-smf oai-spgwu oai-ext-dn
Creating network "rfsim5g-oai-public-net" with driver "bridge"
Creating network "rfsim5g-oai-traffic_net-net" with driver "bridge"
Creating rfsim5g-oai-nrf ... done
Creating rfsim5g-mysql ... done
Creating rfsim5g-oai-spgwu ... done
Creating rfsim5g-oai-amf ... done
Creating rfsim5g-oai-smf ... done
Creating rfsim5g-oai-ext-dn ... done
Wait for a bit.
$ docker-compose ps -a

rfsim5g-oai-spgwu /openair-spgwu-tiny/bin/en ... Up (healthy) 2152/udp, 8805/udp
At this point, you can prepare a capture on the newly-created public docker bridges:
$ ifconfig

Making sure the OAI UE is connected:
$ docker exec -it rfsim5g-oai-nr-ue /bin/bash

3. Check traffic
3.1. Check your Internet connectivity
$ docker exec -it rfsim5g-oai-nr-ue /bin/bash
root@bb4d400a832d:/opt/oai-nr-ue# ping -I oaitun_ue1 -c 10 www.lemonde.fr

--- s2.shared.global.fastly.net ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 9011ms

If it does not work, certainly you need to modify the DNS values in the docker-compose.
But you can also check with the ext-dn container (IP address is 192.168.72.135 in docker-compose)
$ docker exec -it rfsim5g-oai-nr-ue /bin/bash
root@bb4d400a832d# ping -I oaitun_ue1 -c 2 192.168.72.135
PING 192.168.72.135 (192.168.72.135) from 12.1.1.2 oaitun_ue1: 56(84) bytes of data.
64 bytes from 192.168.72.135: icmp_seq=1 ttl=63 time=10.9 ms
64 bytes from 192.168.72.135: icmp_seq=2 ttl=63 time=16.5 ms
--- 192.168.72.135 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 10.939/13.747/16.556/2.810 ms
Let now try to check UDP traffic in Downlink.
You will need 2 terminals: one in the NR-UE container, one in the ext-dn container.
3.2. Start the iperf server inside the NR-UE container
$ docker exec -it rfsim5g-oai-nr-ue /bin/bash
root@bb4d400a832d:/opt/oai-nr-ue# iperf -B 12.1.1.2 -u -i 1 -s
------------------------------------------------------------
Server listening on UDP port 5001
Binding to local address 12.1.1.2
Receiving 1470 byte datagrams
UDP buffer size: 208 KByte (default)
------------------------------------------------------------
3.3. Start the iperf client inside the ext-dn container
$ docker exec -it rfsim5g-oai-ext-dn /bin/bash
root@f239e31a0bd0:/# iperf -c 12.1.1.2 -u -i 1 -t 20 -b 500K
------------------------------------------------------------
Client connecting to 12.1.1.2, UDP port 5001
Sending 1470 byte datagrams, IPG target: 22968.75 us (kalman adjust)
UDP buffer size: 208 KByte (default)
