Worker node group settings

These settings are set when creating a cluster or when adding a worker node group to an existing cluster:

  • Name groups: must start with a letter. Can only consist of lowercase Latin letters, numbers, and hyphens - as a separator.

  • Worker node settings:

    • Node type: virtual machine template for worker-nodes.

      Templates with high-performance CPUs are available upon request to support. To take advantage of these templates, select the "Show high performance CPUs only" option.

      See Available computing resources for details.

    • Availability zone: availability zone for nodes.

      For high availability, it is recommended to create several groups of nodes in different availability zones and place application replicas on these nodes so that the replicas are also in different availability zones.

    • Storage settings:

      • Disk type: storage type to be used by nodes.

      • Disk size: the larger the disk size, the better its performance in some disk operations.

    • Number of nodes: at least one node. One node does not provide high availability on the level of an individual group of nodes, two nodes or more do.

    • Enable autoscaling: enable this option to allow auto-scaling the number of nodes in the group. Then set the minimum and maximum number of nodes. Within these limits the scaling will be performed.

    • Percentage of unavailable nodes when updating the cluster version: the percentage number of nodes that can be taken out of the node group when cluster update procedure is performed.

    • Kubernetes parameters: labels, taints and tolerations.

      More about labels and taints.
