5G Deployment Guide
===================

Deployment Overview
-------------------
SD-Core is released with Helm chart and container images.
We recommend using **Kubernetes** and **Helm** to deploy SD-Core.
SD-Core images are hosted on docker hub.

Deployment Options
------------------

Development Environments
""""""""""""""""""""""""

Please refer (see :ref:`aiab-guide`) to setup 5G development environment.

Production Environments - 5G
""""""""""""""""""""""""""""

To install SD-Core into your Kubernetes cluster, follow instructions

Step1 - Clone SD-Core 5G Helm chart
'''''''''''''''''''''''''''''''''''
.. code-block::

  git clone "https://gerrit.opencord.org/sdcore-helm-charts"
  cd sdcore-helm-charts/sdcore-helm-charts/
  helm dep update #Update Helm dependencies

Step2 - Prepare your Helm value for 5G
''''''''''''''''''''''''''''''''''''''

You can modify existing values.yaml directly, but we recommend composing another value
file myvalues.yaml using values.yaml as an example. We are highlighting a few things we
need to modify here. More explanation of the supported Helm values can be found in the
Configuration section below.

Step3 - Install 5G using SD-Core umbrella helm chart
''''''''''''''''''''''''''''''''''''''''''''''''''''

The following command will deploy the SD-Core helm chart with release name sdcore-5g in the sdcore-5g namespace.

.. code-block::

    helm install -n sdcore-5g --create-namespace -f myvalues.yaml sdcore-5g  ~/cord/sdcore-helm-charts/sdcore-helm-charts

To verify the installation:

.. code-block::

    helm -n sdcore-5g ls
    xxxx@node:~$ helm -n sdcore-5g ls
    NAME     	NAMESPACE	REVISION	UPDATED                                	STATUS  	CHART         	APP VERSION

To uninstall:

.. code-block::

    helm -n sdcore-5g uninstall sdcore-5g
    kubectl delete namespace sdcore-5g # also remove the sdcore-5g if needed

Cloud Native Configuration - 5G
""""""""""""""""""""""""""""""""

Following configuration need to be enabled in 5G helm values override file

Enable AMF Sctp Load Balancer
'''''''''''''''''''''''''''''
Edit sd-core-5g-values.yaml as following

.. code-block::

    sctplb:
      deploy: true

Enable SMF DB Store
'''''''''''''''''''
Edit sd-core-5g-values.yaml as following

.. code-block::

    smf:
      cfgFiles:
        smfcfg.conf:
          configuration:
            enableDBStore: true

Enable UPF-Adapter
''''''''''''''''''
Edit sd-core-5g-values.yaml as following

.. code-block::

    upfadapter:
      deploy: true

Enable NRF Keep-Alive
''''''''''''''''''''''
Edit sd-core-5g-values.yaml as following

.. code-block::

    nrf:
      cfgFiles:

          configuration:
            mongoDBStreamEnable: false
            nfProfileExpiryEnable: true
            nfKeepAliveTime: 60

Enable UE IP-Address allocation by UPF
''''''''''''''''''''''''''''''''''''''
This is optional feature to allocate UE IP-Address via UPF rather than locally via SMF.

.. code-block::

 cpiface:
   dnn: "internet"
   hostname: "upf"
   enable_ue_ip_alloc: true
   ue_ip_pool: "172.250.0.0/16"
