Managed Kubernetes applications

Last update: August 07 2025

In a Managed Kubernetes cluster, you can use applications that extend Kubernetes functionality — for example, applications that help manage traffic or collect and process logs.

You can install and uninstall applications using Helm and via the control panel. Currently, only the NGINX Ingress Controller application can be installed and uninstalled via the control panel.

NGINX Ingress Controller Application

NGINX Ingress Controller is an Ingress controller for NGINX that provides application-level (L7) routing of incoming traffic. It routes traffic based on rules defined in Ingress. For more information about NGINX Ingress Controller, see the NGINX Ingress Controller documentation.

The NGINX Ingress Controller application can be installed and uninstalled via the control panel and Helm chart.

Install NGINX Ingress Controller

Control panel

A load balancer of type Basic with redundancy and a public IP address will be created for the application. You cannot change the type in the created load balancer. If you want to change the load balancer type or its parameters, install the application using Helm-chart.

1. Ensure that the pool has a quota of at least one public IP address allocated.
2. In the dashboard, on the top menu, click Products and select Managed Kubernetes.
3. Open the cluster page → Applications tab.
4. In the Available for Installation block, click NGINX Ingress Controller.
5. Check the price of the load balancer and public IP address.
6. Click Install. A new load balancer of type Basic with redundancy with a public IP address will be created. The load balancer will appear in the control panel: in the top menu, click Products and select Cloud Servers → Balancers section → Balancers tab.

Helm

A load balancer with a public IP address will be automatically created with the Ingress Controller. By default, a load balancer of type Basic with redundancy is created, but you can choose the type of load balancer and configure other parameters for it — see the Configure a Load Balancer instructions for more information on load balancer parameters . The load balancer will be the entry point for accessing applications in the cluster, so you do not need to create an additional internal load balancer.

Without load balancer configuration

1. Ensure that the pool has a quota of at least one public IP address allocated.

2. Connect to the cluster.

3. Install the Helm package manager.

4. Add the ingress-nginx repository to Helm:

   helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx

5. Install the Ingress Controller:

   helm install ingress-nginx/ingress-nginx --generate-name

6. Check that the Ingress Controller is installed:

   kubectl get pods

   Ingress Controller information will appear in the response:

   NAME                                                   READY   STATUS    RESTARTS   AGE
   ingress-nginx-1652172027-controller-6d765d1688-vr7ab   1/1     Running   0          51s

   A new load balancer will be created. It will appear in the Control Panel: in the top menu, click Products and select Cloud Servers → Balancers section → Balancers tab.

With load balancer configuration

1. Ensure that the pool has a quota of at least one public IP address allocated.

2. Connect to the cluster.

3. Install the Helm package manager.

4. Add the ingress-nginx repository to Helm:

   helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx

5. Get the default values and save them to the values.yaml file:

   helm inspect values ingress-nginx/ingress-nginx > values.yaml

6. In the annotations block of the values.yaml file, add the necessary parameters for the load balancer — for more information about load balancer parameters, see the Configure Load Balancer instruction.

Manifest fragment with annotations block:

metadata:
  name: loadbalancer-name
  labels:
    app: nginx
  annotations:
    service.beta.kubernetes.io/openstack-internal-load-balancer: "true"

7. Save your changes.

8. Install the Ingress Controller:

   helm install ingress-nginx/ingress-nginx --generate-name -f values.yaml

9. Check that the Ingress Controller is installed:

   kubectl get pods

   Ingress Controller information will appear in the response:

   NAME                                                   READY   STATUS    RESTARTS   AGE
   ingress-nginx-1652172027-controller-6d765d1688-vr7ab   1/1     Running   0          51s

   A new load balancer will be created. It will appear in the Control Panel: in the top menu, click Products and select Cloud Servers → Balancers section → Balancers tab.

Remove NGINX Ingress Controller

Control panel

1. In the dashboard, on the top menu, click Products and select Managed Kubernetes.
2. Open the cluster page → Applications tab.
3. In the Installed applications block, from the the application, select Uninstall.

Helm

1. Connect to the cluster.

2. Uninstall the app:

   helm uninstall <application_name>

   Specify <application_name> is the name of the application.
