Configure a cluster

Daria Barysheva
IMPORTANT
There is usually no need to change cluster configuration parameters — leave all the parameters at the default values.

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

  1. From the CLUSTERS tab switch to the cluster configuring. To do this, click the row that contains the added cluster or click the icon in the Config column. Both methods open the cluster menu.

  2. Open the Configuration tab in the cluster menu, fill in all necessary parameters, and click Save.

     
    Cluster configuration parameters are listed below. Basically, they describe paths to the repositories that are used during the installing process — depending on the cluster operation system (CentOS, ALT Linux or Red Hat). Only the marked repositories are registered on the cluster servers. For each parameter, you can change the default url to the required one.
