# Service Management and Orchestration (SMO) This project focus on a docker-compose deployment solution for SMO/OAM Components. ## Introduction With respect to OAM the SMO implements the O1-interface consumers. According to the O-RAN OAM Architecture and the O-RAN OAM Interface Specification, the SMO implements a NETCONF Client for configuration and a HTTP/REST/VES server for receiving all kind of events in VES format. The setup contains an OpenDaylight based NETCONF client and an ONAP VES Collector. ## SMO OAM Components This docker-compose file starts a pre-configured, self-contained SDN-R solution with the following components. * **Identity** ... representing an KeyCloak based identity service for centralized user management. Please note that the implementation does not support IPv6. Therefore, its own network is required called 'DMZ'. * **Controller** single node instance ... representing the NETCONF consumer on the Service Management and Orchestration framework (SMO) for O-RAN O1 interface and/or O-RAN OpenFronthaul Management Plane and/or other NETCONF/YANG schemas implemented by the OpenDaylight project. * **VES collector** ... representing the VES (REST) provider at SMO for all kind of events. * **Messages** ... representing SMO MessageRouter component, includes message-router ## Prerequisites ### Operating (HOST) System ``` $ cat /etc/os-release | grep PRETTY_NAME PRETTY_NAME="Ubuntu 22.04.2 LTS" ``` ### Docker ``` $ docker --version Docker version 23.0.1, build a5ee5b1 ``` Please follow the required docker daemon configuration as documented in the following README.md: - [./smo/common/docker/README.md](./smo/common/docker/README.md) ### Docker Compose ``` $ docker compose version Docker Compose version v2.17.2 ``` ### GIT ``` $ git --version git version 2.34.1 ``` ### Python ``` $ python3 --version Python 3.10.6 ``` A python parser package is required. ``` sudo apt install python3-pip pip install jproperties ``` It is beneficial (but not mandatory) adding the following line add the end of your ~/.bashrc file. I will suppress warnings when python script do not verify self signed certificates for HTTPS communication. ``` export PYTHONWARNINGS="ignore:Unverified HTTPS request" ``` ### ETC Host (DNS function) Please modify the /etc/hosts of your system. * \: is the hostname of the system, where the browser is started * \: is the IP address of the system where the solution will be deployed For development purposes and may reference the same system. ``` $ cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 # SMO OAM development system smo.o-ran-sc.org gateway.smo.o-ran-sc.org identity.smo.o-ran-sc.org messages.smo.o-ran-sc.org ves-collector.oam.smo.o-ran-sc.org odlux.oam.smo.o-ran-sc.org controller.oam.smo.o-ran-sc.org ``` ## Expected Folder Structure The following figure show the expected folder structure for the different docker-compose file and its configurations. ``` ├── network │ ├── .env │ ├── config.py │ ├── docker-compose.yml │ │ │ ├── ntsim-ng-o-du │ └── ntsim-ng-o-ru └── smo ├── apps │ ├── .env │ ├── docker-compose.yml │ └── flows ├── common │ ├── .env │ ├── docker-compose.yml │ │ │ ├── docker │ ├── gateway │ ├── identity │ ├── messages │ ├── kafka │ └── zookeeper └── oam ├── .env ├── docker-compose.yml │ ├── odlux ├── controller └── ves-collector ``` ## Usage ### Bring Up Solution #### Short story The following commands should be invoked. More detailed can be found in the next chapters. ``` docker compose -f smo/common/docker-compose.yml up -d # wait until the cpu load is low again python smo/common/identity/config.py docker compose -f smo/oam/docker-compose.yml up -d docker compose -f smo/apps/docker-compose.yml up -d # wait until the cpu load is low again docker compose -f network/docker-compose.yml up -d # wait about 2min docker restart ntsim-ng-o-du-1122 python network/config.py ``` #### Check (adjust if required) environment variables ``` nano smo/common/.env nano smo/oam/.env nano network/.env ``` #### Startup solution Please note that it is necessary to configure first the identity service, before starting further docker images. The several docker-compose yml files must be started in the right order as listed below: ``` docker compose -f smo/common/docker-compose.yml up -d python smo/common/identity/config.py ``` The python script configure the users within the identity service (keycloak). A system user (%USER) is also created with administration rights. ``` docker compose -f smo/oam/docker-compose.yml up -d ``` Looking into the ONAP SDN-R logs will give you the startup procedure. ``` docker logs -f controller ``` If you see the login page (https://odlux.oam.smo.o-ran-sc.org) you are good to go and can start the (simulated) network. ``` docker compose -f network/docker-compose.yml up -d ``` Usually the first ves:event gets lost. Please restart the O-DU docker container(s) to send a second ves:pnfRegistration. ``` docker compose -f network/docker-compose.yml restart ntsim-ng-o-du-1122 python network/config.py ``` The python script configures the simulated O-DU and O-RU according to O-RAN hybrid architecture. O-DU - NETCONF Call HOME and NETCONF notifications O-RU - ves:pnfRegistration and ves:fault, ves:heartbeat ![ves:pnfRegistration in ODLUX](docs/nstim-ng-connected-after-ves-pnf-registration-in-odlux.png "ves:pnfRegistration in ODLUX") 'True' indicated that the settings through SDN-R to the NETCONF server were successful. SDN-R reads the fault events from DMaaP and processes them. Finally the fault events are visible in ODLUX. ![ves:fault in ODLUX](docs/ves-fault-in-odlux.png "ves:fault in ODLUX") ### Log files and karaf console #### ODL karaf.logs ``` docker exec -it controller tail -f /opt/opendaylight/data/log/karaf.log ``` #### ves-collector logs ``` docker logs -f ves-collector ``` ### Customizing Solution '.env' file contains customizing parameters ### Verification Solution #### Access to SDN-R ODLUX ##### Login into SDN-R https://odlux.oam.smo.o-ran-sc.org User: admin // see .env file Password: Kp8bJ4SXszM0WXlhak3eHlcse2gAw84vaoGGmJvUy2U In case of trouble, please update the commands with your customized '.env' file. ### Terminate solution To stop all container please respect the following order ``` docker compose -f network/docker-compose.yml down docker compose -f smo/apps/docker-compose.yml down docker compose -f smo/oam/docker-compose.yml down docker compose -f smo/common/docker-compose.yml down ``` ### Cleanup !!! be careful if other stopped containers are on the same system ``` docker system prune -a -f ``` ### Troubleshooting In most cases the .env setting do not fit to the environment and need to be adjusted. Please make sure that the network settings to not overlap with other networks. The commands ... ``` docker ps -a docker-compose ps docker rm -f $(docker ps -aq)
