Aether SD-Core Developer Guide
==============================

Clone Repositories
------------------

Clone the following repositories, using your gerrit ids as necessary::

    mkdir -p ~/cord    #need to clone below 2 repos in this directory
    git clone "ssh://<username>@gerrit.opencord.org:29418/helm-charts"
    git clone "ssh://<username>@gerrit.opencord.org:29418/aether-helm-charts"

    cd ~  #go back to home directory
    git clone "ssh://<username>@gerrit.opencord.org:29418/aether-in-a-box"

Start the 4G Core
-----------------

Deploy Aether-in-a-Box and start the 4G core::

    cd aether-in-a-box

    #create K8s cluster for you and also start 4G network functions and carry out 1 ping test
    make test

Apply the necessary pull secrets
--------------------------------

The deployment may fail and leave pods in ImagePullBackoff status if the
necessary secrets are not applied.
Obtain the secret from ONF, and then execute the following::

    cat > ~/registry-secret.json
         ... paste the secret here ...
    kubectl apply -f ~/registry-secret.json



Transition from 4G Core to 5G Core
----------------------------------

Before starting the 5G core, the 4G Core must be stopped::

    make reset-test  #this does not destroy K8s cluster.

Now, start the 5G Core::

    make 5gc  #this will start all 5G network functions with default images.

    kubectl get pods -n omec #verify that all 5g pods are started.

Sample output::

Developer Loop
--------------

Deploy custom images by editing `~/aether-in-a-box/aether-in-a-box-values.yaml`::

    images:
        tags:
            webui: registry.aetherproject.org/omecproject/5gc-webui:onf-release3.0.5-roc-935305f
        pullPolicy: IfNotPresent
        pullSecrets:
            - name: "aether.registry"

Stop the 5G Core and start it again::

    make reset-5g-test
    make 5gc
