The Avi K8s Operator (AKO) is used to provide L4-L7 load balancing for applications deployed in a kubernetes cluster for north-south traffic.

The AKO controller ingests the Kubernetes API server object updates to construct corresponding objects in the Avi controller. The Avi controller then programs the datapath using appropriate APIs to enable traffic routing for requested applications.

AKO runs as a POD inside the kubernetes cluster.

To Run AKO you need the following pre-requisites (on-prem clusters):

• Step 1: An Avi Controller with a vCenter cloud or No Access Cloud configured.

• Step 2: If your POD CIDRs are not routable:

  • Configure the vip network in the values.yaml of AKO.
  • Also provide the backend network information (from 1.2.1 onwards).

For additional settings related to values.yaml pls refer here

• Step 2.1: If your POD CIDRs are routable (or you are using the NodePort mode), you don't have to worry about the backend network.
• Step 3: Kubernetes 1.16+.
• Step 4: helm cli pointing to your kubernetes cluster.

NOTE: We only support helm 3.0 and above. For a more detailed installation instruction pls refer here

Step 1: Create the avi-system namespace:

kubectl create ns avi-system

Step 2: Clone this repository, go inside the helm directory and run:

helm install ./ako --name my-ako-release --namespace=avi-system --set configs.controllerIP=10.10.10.10

Use the helm/ako/values.yaml to edit values related to Avi configuration. A list of editable parameters can be found here

Simply run:

Step1:

helm delete <ako-release-name> -n avi-system

Step 2:

kubectl delete ns avi-system

AKO can be built as a docker container using the make command. Simply clone the repository and run:

make docker

AKO runs a simulation of the Kubernetes APIs using the kubernetes FakeClient and it also simulates the Avi controller by exploiting the httptest server from golang. In order to run the end to end unit tests, you can execute:

make int_test
