System requirements for a client cluster

Client cluster must consist of at least one Control Plane node and two Worker nodes. To ensure fault tolerance, the cluster must consist of at least three Control Plane nodes and two Worker nodes. For a client cluster, the requirements for the number and computing resources of servers are specified in the tables below.

For client clusters, the concept of an infrastructure node - Infra - has been introduced. Worker is a Worker node on which cluster system services will be deployed as a priority. To ensure that system services are hosted only on Infra nodes, 3 Infra nodes are recommended. Pay attention!

• If you create a cluster with a group of Infra nodes, the requirements for Worker nodes on which custom loads will be deployed will consist of several values: the requirements indicated in the table for Worker + resource requirements from those custom services that are planned to be deployed on these nodes.
• If you create a cluster without selecting a group of Infra nodes, the requirements for Worker nodes on which system and custom loads will be deployed will consist of several values: the requirements indicated in the table for Infra Worker + resource requirements from those custom services that are planned to be deployed on these nodes.
