You can manually scale up or down a Platform9 Managed Kubernetes cluster regardless of what private or public cloud its deployed on.
For clusters created with AWS cloud provider, if you have enabled horizontal auto-scaling on the cluster, you can change the minimum number of nodes and the maximum number of nodes available for scaling the cluster up or down automatically.
Number of Worker Nodes denotes the minimum number of worker nodes to which the cluster can auto-scale down, and the Maximum Number of Worker Nodes denotes the maximum number of worker nodes to which the cluster can auto-scale up.
You must be a Platform9 administrator to perform this operation.
Follow the steps given below to scale a cluster:
- Navigate to Infrastructure > Cluster.
- Select the cluster that you wish to scale.
- Click Scale Cluster seen above the list of clusters.
- Change the current number of worker nodes to your desired number. If the number of workers you specified is smaller than the current number of workers, your cluster will be scaled down to that number. If the number you specified is greater than the current number, your cluster will be scaled up.
- Enter the Number of worker nodes. If auto-scale is enabled on the cluster, this field indicates the minimum number of worker nodes. You can change it to a new value, if required.
- If auto-scale is enabled on the cluster, and you wish to change the Maximum Number of nodes, enter the new value for Maximum Number of nodes.
- Click Scale Cluster.
The changes related to scaling of the cluster are saved.
