Cluster Templates

What Are Cluster Templates?

Cluster templates are templates that enable a fast and uniform creation of Kubernetes clusters. With cluster templates, you can create clusters with a few clicks without having to re-enter settings such as credentials, network settings, and availability zones each time.

Creating Cluster Templates

To create a Cluster Template, select the Cluster Templates menu item in the sidebar and click the Create Cluster button.

The cluster creation process known from section Creating a cluster opens. Enter all required data for the cluster creation. In the last step “Summary”, do not click on Create Cluster but on Save Cluster Template.

Now the dialog Save Cluster Template opens. Here you can define the name and storage scope.

Templates can be saved in 2 different scopes:

  • On project level: All users of the project can use the template.
  • On user level: The template can be used in all projects where the user has write access. Other users cannot use the template.
