Scaling the cluster🔗︎

Any cluster created with Kubitect can be subsequently scaled. To do so, simply change the configuration and reapply it using the scale action.

Info

Currently, only worker nodes and load balancers can be scaled.

Export the cluster configuration🔗︎

Exporting the current cluster configuration is optional, but strongly recommended to ensure that changes are made to the latest version of the configuration. The cluster configuration file can be exported using the export command.

kubitect export config --cluster my-cluster > cluster.yaml

Scale the cluster🔗︎

In the configuration file, add new or remove existing nodes.

cluster.yaml
cluster:
  ...
  nodes:
    ...
    worker:
      instances:
        - id: 1
        #- id: 2 # Worker node to be removed
        - id: 3 # New worker node
        - id: 4 # New worker node

Apply the modified configuration with action set to scale: 

kubitect apply --config cluster.yaml --action scale

As a result, the worker node with ID 2 is removed and the worker nodes with IDs 3 and 4 are added to the cluster.
