# HSS
cd ../hss
docker build --force-rm -t docker_nextepc_hss .
docker run -dit -v "$(pwd)":/mnt/hss -p 3000:3000 -e MME_IP='172.18.0.3' --net epc_net --ip 172.18.0.2 --name hss docker_nextepc_hss

# PCRF
cd ../pcrf
docker build --force-rm -t docker_nextepc_pcrf .
docker run -dit -v "$(pwd)":/mnt/pcrf -e PGW_IP='172.18.0.5' -e HSS_IP='172.18.0.2' --net epc_net --ip 172.18.0.6 --name pcrf docker_nextepc_pcrf

# SGW
cd ../sgw
docker build --force-rm -t docker_nextepc_sgw .
docker run -dit -v "$(pwd)":/mnt/sgw -p 2152:2152/udp --net epc_net --ip 172.18.0.4 --name sgw docker_nextepc_sgw

# PGW
cd ../pgw
docker build --force-rm -t docker_nextepc_pgw .
docker run -dit -v "$(pwd)":/mnt/pgw --cap-add=NET_ADMIN --device /dev/net/tun -e PCRF_IP='172.18.0.6' --sysctl net.ipv4.ip_forward=1 --net epc_net --ip 172.18.0.5 --name pgw docker_nextepc_pgw

# MME
cd ../mme
docker build --force-rm -t docker_nextepc_mme .
docker run -dit -v "$(pwd)":/mnt/mme -p 36412:36412/sctp -e HSS_IP='172.18.0.2' -e SGW_IP='172.18.0.4' -e PGW_IP='172.18.0.5' --net epc_net --ip 172.18.0.3 --name mme docker_nextepc_mme

Steps when using docker-compose

cd ..
docker-compose up

Configuration

The configuration files for each of the Core Network component can be found under their respective folder. Edit the .yaml files of the components before deploying each of the container

Register a UE information

Open (http://<DOCKER_HOST_IP>:3000) in a web browser, where <DOCKER_HOST_IP> is the IP of the machine/VM running the open5gs containers. Login with following credentials

Username : admin
Password : 1423

Using Web UI, add a subscriber

eNB settings

On the eNB, make sure to have the static route to SGW container (since internal IP of the SGW container is advertised in S1AP messages and UE wont find the core in Uplink)

ip r add <SGW_CONTAINER_IP> via <DOCKER_HOST_IP>
