OAI O-RAN 7.2 Front-haul Docker Compose

![Docker deploy 7.2](../../../doc/images/docker-deploy-oai-7-2.png)

This docker-compose is designed to use `OAI-gNB` with a 7.2 compatible Radio Unit. Before using this docker compose you have to configure
the host machine as per the [ORAN_FHI7.2_Tutorial](../../../doc/ORAN_FHI7.2_Tutorial.md). The container image used by the docker compose file is tested only on `Ubuntu 22.04` and `RHEL 9.4` docker host.

## Build Image (Optional)

Refer to [OAI Docker/Podman Build and Usage Procedures](../../../docker/README.md)

## Configure Networking

### SR-IOV Virtual Functions (VFs)

In docker-compose environment there is no automated method
to configure the VFs on the fly. The user will have to manually configure
C/U plane VFs before starting the container `OAI-gNB`.

You can follow the step
[configure-network-interfaces-and-dpdk-vfs](../../../doc/ORAN_FHI7.2_Tutorial.md#configure-network-interfaces-and-dpdk-vfs).

### Interface towards AMF (N2)

For `N2` interface we are using `macvlan` driver of docker.

You can use the `bridge` driver, in situation

- When the core network is running on the same machine
- or different machine but you have configured
needed `ip route` and forwarding to access the core network from RAN host.

To configure docker `macvlan` network
you need to choose `ipam.config` and `driver_opts.parent` are per your environment

```
    oai-net:
        driver: macvlan
        name: oai-net
        ipam:
            config:
                - subnet: "172.21.16.0/22"
                  ip_range: "172.21.18.20/32"
                  gateway: "172.21.19.254"
        driver_opts:
            com.docker.network.bridge.name: "oai-net"
            parent: enp193s0f0
```

To configure `bridge` network you need to choose `ipam.config.subnet` as per your environment.

```
    oai-net:
        driver: bridge
        name: oai-net
        ipam:
            config:
                - subnet: 192.168.72.128/26
        driver_opts:
            com.docker.network.bridge.name: "oai-net"
```

## Deploy OAI-gNB Container

The [configuration file](../../conf_files/gnb.sa.band77.273prb.fhi72.4x4-vvdn.conf) used by docker compose is configured for VVDN RU.

```bash
docker-compose up -d
```

To check the logs

```bash
docker logs oai-gnb -f
```
