AKS Cluster

How to Optimize Azure Managed Kubernetes Clusters (AKS)

1. Download Kaytu CLI

MacOS

brew tap kaytu-io/cli-tap && brew install kaytu

Linux

curl -fsSL https://raw.githubusercontent.com/kaytu-io/kaytu/main/scripts/install.sh | sh

Windows (and all Binaries) Download Windows (Linux, and MacOS) binary from releases

kaytu login

Install the Kaytu CLI plugin

kaytu plugin install kubernetes

If you don't have AWS CLI, go here and install it.

Run to confirm you are logged in to the correct account

az login

az aks get-credentials -g ${RESOURCE_GROUP_NAME} -n ${AKS_NAME}

Replace Resource Group Name and ASK Name.

Get the Kubeconfig

kubelogin convert-kubeconfig -l azurecli

To confirm you are connected to the cluster:

kubectl get nodes

Enrollment keys allow the Kubernetes cluster to get optimization results from the Kaytu platform.

kaytu apikey generate [cluster-name]

Replace Cluster name with the Kubernetes Cluster.

Please copy the enrollment key provided. Unfortunately, you won't be able to view the key at a later time.

helm repo add kaytu-io https://kaytu-io.github.io/kaytu-charts

Once that completes, we can run update Charts:

helm repo update

In values.yaml file, please make sure the following variables are correctly configured:

kaytu.kaytu.authToken needs to be populated with the key generated in Step 4.

kaytu.kaytu.prometheus.address needs to be pointed to the Prometheus endpoint.

This will create a namespace if one doesn't exist for Kaytu

helm install --create-namespace -n kaytu-system my-kaytu-agent kaytu-io/kaytu-agent -f values.yaml

Check the logs and wait for the optimization cycle to be over

kubectl logs -f kaytu-agent-0

Wait for the log containing the optimization cycle to be completed.
