Register the Worker Cluster
Introduction
Before creating a slice across your Kubernetes clusters, you must register your worker clusters with the KubeSlice Controller.
Prerequisites
Before you begin, ensure the following prerequisites are met:
- You have the KubeSlice Controller installed on a separate cluster. For more information, see Installing the KubeSlice Controller.
- You have set up the environment for the worker clusters. For more information, see Prerequisites.
- You have authenticated the worker clusters with the cloud providers. For more information, see Preparing the clusters for registration.
- You have cluster administrator privileges to install the Slice Operator.
Install Istio
Istio is an open source service mesh that is used frequently to connect and secure microservices within a cluster. The below instructions will install istio from the helm repository chart.
warning
Istio does not work with kind clusters.
caution
You can skip these steps if you have already installed the recommended Istio version in the cluster.
Perform these steps:
- Switch the context to the cluster that will be registered with the KubeSlice Controller.
kubectx <cluster name> - Create the
istio-systemnamespace using the following command:kubectl create ns istio-system - Install the
istio-chartfrom the helm repository using the following command:helm install istio-base kubeslice/istio-base -n istio-system - Install the
istio-discoverychart from the helm repository using the following command:helm install istiod kubeslice/istio-discovery -n istio-systemcaution
Repeat these steps to install Istio on other worker clusters.
Validate the Installation of Istio
Validate the installation by checking the pods status belonging to the istio-system namespace.
kubectl get pods -n istio-system
Example Output
NAME READY STATUS RESTARTS AGE
istiod-66f576dd98-jtshj 1/1 Running 0 100s
Create the Cluster Registration YAML File
The following information is required to create your cluster registration .yaml file.
info
For example YAML files on kind clusters, see kind YAML examples.
info
Register the worker clusters with the KubeSlice Controller by applying the YAML on the Project namespace.
info
The cluster registration .yaml file can have multiple clusters listed to register with the KubeSlice Controller.
Create the cluster registration YAML file using the following template.
info
To understand more about the configuration parameters, see Cluster Registration Configuration Parameters

Applying the Cluster Registration YAML File
The following information is required.
| Values | Description |
|---|---|
| <cluster name> | The name of the cluster. |
| <cluster registration> | The name of the registration file. |
| <project namespace> | The namespace of your project. |
Perform these steps:
- Switch the context to the cluster where the KubeSlice Controller is installed.
kubectx <cluster name> - Use the following command to apply the YAML file.You must apply the cluster registration YAML file on
your Project namespace.
kubectl apply -f <cluster registration>.yaml -n <project namespace>
Validate the Registered Clusters
Validate the registered clusters by using the following command:
kubectl get clusters -n kubeslice-<project name>
Example
kubectl get clusters -n kubeslice-avesha
Expected Output
NAME AGE
aks-worker-2 17s
gke-worker-1 17s
success
You have successfully registered the Worker clusters with the KubeSlice Controller.
Install the Slice Operator
Install the Slice Operator on the worker cluster that you just registered.Before installing the Slice Operator in your registered cluster, you must get the secrets and the endpoints from the KubeSlice Controller.
Get the Secrets of the Registered Cluster
After registering the worker cluster with the KubeSlice Controller, you will get a secret listed under the project namespace. The secret contains access information for the Slice Operator on the worker cluster to communicate with the KubeSlice Controller.
info
Alternatively, you can use the script to create your values .yaml file.
See Script to get the secrets of the worker cluster.
Switch the context to the controller cluster.
kubectx <cluster name>Get the list of secrets belonging to the project namespace using the following command:
kubectl get secrets -n kubeslice-<projectname>Example
kubectl get secrets -n kubeslice-aveshaExample Output

kubeslice-rbac-worker-aks-worker-2-token-lwzj2 kubernetes.io/service-account-token 5 43sThe name of the secret is in this format:
kubeslice-rbac-<registered cluster secret name>-token. For example,kubeslice-rbac-worker-aks-worker-1-token-hml58- this secret is meant for a worker cluster that was registered using the name aks-worker-1.Retrieve the details of the secret using the following command:
kubectl get secrets <worker-cluster-secret-name> -o yaml -n kubeslice-<projectname>Example
kubectl get secrets kubeslice-rbac-worker-aks-worker-1-token-hml58 -o yaml -n kubeslice-ciscoExample Output

Apply the Values File
The following information is required to apply the YAML file.
| Parameter | Description |
|---|---|
<cluster name\> | The name of the cluster. |
<values\> | The file name with the values. |
Perform these steps:
- Switch the context to the registered worker cluster.
kubectx <cluster name> - Use the following command to apply the values file on the
kubeslice-systemnamespace:helm install kubeslice-worker kubeslice/kubeslice-worker -f <full path of secrets file>.yaml -n kubeslice-system --create-namespace
Validate the Slice Operator Installation
To validate the Slice Operator installation in the registered cluster, check the pods belonging to the
kubeslice-system namespace by running the following command:
Example
kubectl get pods -n kubeslice-system
Example Output
NAME READY STATUS RESTARTS AGE
forwarder-kernel-rjmkr 1/1 Running 0 75s

info
You must repeat the same sequence of steps that are getting the secrets, creating the YAML file, and applying the YAML on each worker cluster to install the Slice Operator on other registered worker clusters.
success
You have successfully installed the Slice Operator in the worker cluster. Repeat the above steps to install the Slice Operator in all the registered worker clusters.
