Aether In a Box - 5G

Setting Up Aether-in-a-Box - 5G

Aether-in-a-Box (AiaB) provides an easy way to deploy Aether’s SD-CORE components and run basic tests to validate the installation. This guide describes the steps to set up AiaB.

AiaB can be set up with a 4G or 5G SD-CORE. We use SimApp to configure the required subscribers & network slices in SD-CORE for testing core functionality.

Helm charts are the primary method of installing the SD-CORE resources. AiaB offers a great deal of flexibility regarding which Helm chart versions to install:

  • Local definitions of charts (for testing Helm chart changes)

  • Latest published charts (for deploying a development version of Aether)

  • Specified versions of charts (for deploying a specific Aether release)

AiaB can be run on a bare metal machine or VM. System prerequisites:

  • Ubuntu 18.04 or later

  • Kernel 4.15 or later

  • Haswell CPU or newer

Clone Repositories

To initialize the AiaB environment, first clone the following repository:: your Gerrit ID:

cd ~
git clone ""

mkdir -p ~/cord
cd ~/cord
git clone ""


Only one version of the SD-CORE (4G or 5G) can be installed in AIAB environment at a time. The first time you build AiaB, it takes a while because it sets up the Kubernetes cluster. Subsequent builds will be much faster if you follow below steps to delete & redeploy SD-Core (4G/5G) without destroying the Kubernetes

Running 5G Test

To deploy 5G SD-CORE using local helm charts:

make 5g-core

To deploy and test 5G SD-CORE using local helm charts:

make 5g-test

The above step uses gNBSim to perform Registration + UE-Initiated PDU Session Establishment + User Data Packets. To test other procedures, modify gnb.conf in ~/aether-in-a-box/sd-core-5g-values.yaml (refer gNBSim documentation gNBSim Usage)

Developer Loop

Suppose you wish to test a new build of a 5G SD-CORE services. You can deploy custom images by editing ~/aether-in-a-box/sd-core-5g-values.yaml, for example:

    webui: omecproject/5gc-webui:master-7f96cfd

To upgrade a running 5G SD-CORE with the new image, or to redeploy the 5G SD-CORE with the image:

make reset-5g-test # delete 5G deployment if it was already started before updating image
make 5g-core  #now this deployment will use new webui image

Troubleshooting / Known Issues

Deployment Status

If you suspect a problem, first verify that all pods are in Running state:

kubectl -n omec get pods

If the pods are stuck in ImagePullBackOff state, then it’s likely an issue with image name.

Test Failure

If make 5g-test fails consistently, then try to debug the issue by looking at logs at amf, smf.
