+![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` 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](../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.273prb.fhi72.4x4-benetel650.conf) used  by docker compose is configured for Benetel 650 RU (RAN650-1v1.0.4-dda1bf5). 
+
+```bash
+docker-compose up -d
+```
+
+To check the logs
+
+```bash
+docker logs oai-gnb -f
+```
