Preparatory steps

Review the system requirements of the add-on to make sure you have enough resources to install it.
(Optional) Perform manual scaling of worker node groups or set up automatic scaling.

Several installation options are available for the add-on.

Standard installation

Installation on dedicated worker nodes

Quick installation

Install the add-on:
Management console
Terraform
Go to VK Cloud management console.

Select project, where the cluster will be placed.

Go to Containers → Kubernetes clusters.

Click on the name of the required cluster.

Go to Addons tab.

If there are already installed add-ons in the cluster, click on the Add addon button.

Click the Install button on the cert-manager add-on card.

Select the necessary add-on version from the drop-down list.

Click the Install addon button.

Edit if necessary:

selected version;

application name;

the name of the namespace where the add-on will be installed;

add-on settings code.

Click the Install addon button.

The installation of the add-on in the cluster will begin. This process can take a long time.

Install Terraform and configure the environment if it is not already done.

Add to your Terraform configuration files that describe the cluster:

The vkcs_kubernetes_addon resource.

The vkcs_kubernetes_addon data source.

The vkcs_kubernetes_addons data source.

If necessary, adapt the usage examples given for resource and data sources to your task and Terraform configuration (see the links above).

Make sure the configuration files are correct and contain the necessary changes:

terraform validate && terraform plan

Apply the changes:

terraform apply
Verify that the add-on is installed correctly by issuing a test self-signed certificate.

Editing the add-on code is applicable for standard installation and installation on dedicated worker nodes.

The full add-on setup code along with the description of the fields is available on GitHub.

After editing the add-on code continue installing the add-on.
