Master Nodes

Master nodes can be manually added or deleted from Rafay provisioned and managed clusters.

Important

This workflow is supported for manually provisioned clusters.


Manually Provisioned Clusters

Add Master Nodes

  • Create required VMs or instances
  • Sign into the Rafay Console.
  • Select the cluster and click on nodes
  • Click "Add Node" and Follow the Node Installation Instructions to install the Rafay bootstrap agent on the VM

Add Master Manually

  • Approve the node.

Users can optionally enable "auto approval" for new master nodes to join the cluster. Enable the auto approval "toggle" in the cluster configuration page as shown in the screenshot below.

Auto Approve Nodes

  • Click on "Configure" to configure the node with Master Role so that it can be joined as a master node to the cluster.

Configure Master Nodes

  • Click on "Provision" and confirm to start adding this node as a master node to the existing cluster

Confirm Master Nodes

  • It will take couple minutes for the additional master node to be provisioned.

Provision Master Nodes

  • Once the node is done provisioned, it will join the cluster with the Master role

Delete Master Nodes

  • Select the cluster and click on nodes
  • Click on "DELETE" button of the node you would like to delete and confirm the deletion

  • When the node deletion is done, the master node will be removed from the cluster

Important

For manually provisioned clusters, it is the customer's responsibility to deprovision the VM or Instance after deleting the master node from the cluster.
