# O-RAN SMO Package

This project uses different helm charts from different Linux Foundation projects and integrate them into a unique SMO deployment.
<p>The ONAP and ORAN project helm charts are built and then configured by using "helm override" so that it represents a valid ORAN SMO installation.</p>
<p>It contains also provisioning scripts that can be used to bootstrap the platform and execute test use cases, network simulators, a1 simulators, cnf network simulators, etc ...</p>

<strong>Note:</strong>
The CNF part is still a "work in progress" so not well documented, it's a DU/RU/topology server deployment done by ONAP SO instantiation.
It has been created out of the ONAP vfirewall use case.

## Quick Installation on blank node
* Setup a VM with 40GB Memory, 6VCPU, 60GB of disk space.
* Install an ubuntu live server 20.04 LTS (https://releases.ubuntu.com/20.04/ubuntu-20.04.3-live-server-amd64.iso)
* Install snap and restart the shell session: sudo apt-get install snapd -y
* Execute the following commands being logged as root:


	```git clone --recursive https://github.com/sebdet/oran-deployment.git```

	```./dep/smo-install/scripts/layer-0/0-setup-microk8s.sh```

	```./dep/smo-install/scripts/layer-0/0-setup-charts-museum.sh```

	```./dep/smo-install/scripts/layer-0/0-setup-helm3.sh```

	```./dep/smo-install/scripts/layer-1/1-build-all-charts.sh```

	```./dep/smo-install/scripts/layer-2/2-install-oran.sh```

	Verify pods:

	```kubectl get pods -n onap && kubectl get pods -n nonrtric```

	When all pods in "onap" and "nonrtric" namespaces are well up & running:

	```./dep/smo-install/scripts/layer-2/2-install-simulators.sh```

## Quick Installation on existing kubernetes
* Ensure you have at least 20GB Memory, 6VCPU, 60GB of disk space.
* Execute the following commands being logged as root:

        ```git clone --recursive "https://gerrit.o-ran-sc.org/r/it/dep"```

        ```./dep/smo-install/scripts/layer-0/0-setup-charts-museum.sh```

        ```./dep/smo-install/scripts/layer-0/0-setup-helm3.sh```

        ```./dep/smo-install/scripts/layer-1/1-build-all-charts.sh```

        ```./dep/smo-install/scripts/layer-2/2-install-oran.sh```

        Verify pods:

        ```kubectl get pods -n onap && kubectl get pods -n nonrtric```

        When all pods in "onap" and "nonrtric" namespaces are well up & running:

        ```./smo-install/scripts/layer-2/2-install-simulators.sh```

	Verify pods:

	```kubectl get pods -n onap && kubectl get pods -n nonrtric```

	When all pods in "onap" and "nonrtric" namespaces are well up & running:

	```./dep/smo-install/scripts/layer-2/2-install-simulators.sh```

## Download:
Use git clone to get it on your server (github ssh key config is required):

```git clone --recursive git@github.com:gmngueko/oran-deployment.git```


<strong>Note:</strong> The current repository has multiple sub git submodules, therefore the <strong>--recursive</strong> flag is absolutely <strong>REQUIRED</strong>

## Requirements:
* K8S node setup with Helm 3 and Kubectl properly configured (tested with <strong>K8S v1.21.5</strong> and <strong>HELM v3.5.4</strong>).
  FOR K8S installation, multiple options are available:
	- MicroK8S standalone deployment:

		```./dep/smo-install/scripts/layer-0/0-setup-microk8s.sh```

		OR this wiki can help to setup it (<strong>Section 1, 2 and 3</strong>): https://wiki.onap.org/display/DW/Deploy+OOM+and+SDC+%28or+ONAP%29+on+a+single+VM+with+microk8s+-+Honolulu+Setup

	- KubeSpray using ONAP multicloud KUD (https://git.onap.org/multicloud/k8s/tree/kud) installation by executing(this is required for ONAP CNF deployments):

	    ```./dep/smo-install/scripts/layer-0/0-setup-kud-node.sh```


	- Use an existing K8S installation (Cloud, etc ...).
	- ....

* ChartMuseum to store the HELM charts on the server, multiple options are available:
	- Execute the install script:

		```./dep/smo-install/scripts/layer-0/0-setup-charts-museum.sh```

		```./dep/smo-install/scripts/layer-0/0-setup-helm3.sh```

	- Install chartmuseum manually on port 18080 (https://chartmuseum.com/#Instructions, https://github.com/helm/chartmuseum)

## Configuration:
In the ./helm-override/ folder the helm config that are used by the SMO installation.
<p>Different flavors are preconfigured, and should NOT be changed unless you intentionally want to updates some configurations.

## Installation:
* Build ONAP/ORAN charts

	```./dep/smo-install/scripts/layer-1/1-build-all-charts.sh```

* Choose the installation:
	- ONAP + ORAN "nonrtric" <strong>(RECOMMENDED ONE)</strong>:

		```./dep/smo-install/scripts/layer-2/2-install-oran.sh```
	- ORAN "nonrtric" par only:

		```./dep/smo-install/scripts/layer-2/2-install-nonrtric-only.sh```

	- ONAP CNF + ORAN "nonrtric" (This must still be documented properly):

		```./dep/smo-install/scripts/layer-2/2-install-oran-cnf.sh```



* Install the network simulators (DU/RU/Topo):
	- When all pods in "onap" and "nonrtric" namespaces are well up & running:

		```kubectl get pods -n onap && kubectl get pods -n nonrtric```

	- Execute the install script:

		```./dep/smo-install/scripts/layer-2/2-install-simulators.sh```

	- Check the simulators status:

		```kubectl get pods -n network```

	Note: The simulators topology can be customized in the file ./smo-install/helm-override/network-simulators-topology-override.yaml

* SDNR WEB:
	https://<K8SServerIP>:30205/odlux/index.html
* NONRTRIC Dashboard:

  More to come ...

## Uninstallation:
* Execute

	```./dep/smo-install/scripts/uninstall-all.sh```
