There is usually no need to change cluster configuration parameters. You can leave all parameters at the default values.

After creation a new cluster, you can configure it by performing the following steps:

  1. Select a cluster on the Clusters page. To do this, click a cluster name in the Name column.

    Select a cluster
    Select a cluster

  2. Open the Configuration tab on the cluster page. The Configuration tab includes the following sections: Primary configuration, Configuration groups, Ansible settings.

  3. Fill in all necessary parameters on the selected tab and click Save.

Primary configuration

The Configuration → Primary configuration tab allows you to configure the general cluster settings.

Available configuration parameters are listed below. Basically, they describe paths to the repositories that are used during the installing process — depending on the cluster operating system (ALT Linux 10, Astra Linux 1.7, Astra Linux 1.8, RED OS 7, RED OS 8, or Ubuntu 22.04). Only the marked repositories are registered on the cluster servers. For each parameter, you can change the default url to the required one.
