Should I enable the HA control plane?

Yes for production. The standard control plane is a single-zone managed control plane, fine for development; the HA control plane spans multiple zones for production-grade resilience. The cost premium is meaningful but the value is dramatic during a control-plane incident — without HA, your workloads stay running but you can't make any changes.

How does LKE autoscaling work?

Each node pool has a min and max count. The cluster autoscaler watches for unschedulable pods and adds nodes within bounds when needed; it removes nodes that have been underutilized for the configured cool-down period. Set min low enough to save money during quiet periods and max high enough to absorb your worst expected spike.

See It in Action

Your team's first LKE cluster runs every workload on one autoscaling pool of Shared 8 GB nodes. CoreDNS pods get evicted whenever the autoscaler reclaims nodes, causing brief DNS resolution failures cluster-wide. You add a second pool of three fixed Dedicated 4 GB nodes with system-only taints, redeploy CoreDNS and ingress to land on the dedicated pool, and the DNS flapping disappears.

What This Tool Does

Linode Kubernetes Engine (LKE) is the managed Kubernetes offering — control plane is managed, you size and configure the worker pools. The Linode LKE Cluster Builder produces a complete cluster spec including Kubernetes version, region, HA control plane flag, and node pools with autoscaling bounds. Output is ready for the Linode API or Terraform.

Technical Details

The builder collects cluster name, region, Kubernetes version, HA flag, and one or more node pool definitions (instance type, count or min/max for autoscaling). It validates the Kubernetes version against currently-supported LKE versions, checks the instance type against LKE-eligible types, and emits API-ready JSON or `linode_lke_cluster` Terraform.

Common Use Cases

1Standing up a fresh LKE cluster with HA control plane and an autoscaling worker pool sized for the initial workload.
2Adding a second worker pool optimized for a specific workload (Dedicated CPU for production, GPU for inference) to an existing cluster.
3Generating a reproducible cluster spec for an internal team that needs to spin up LKE clusters on demand.
4Migrating self-managed Kubernetes on Linodes to LKE for the operational handover.

Expert Tips

TIP

Use separate node pools for system workloads (DNS, ingress, monitoring agents) and application workloads. Don't let a runaway batch job in the app pool take out cluster DNS.

TIP

Enable HA control plane for any cluster with more than a handful of nodes — the cost differential as a percentage of the total cluster cost shrinks rapidly as you scale up, and HA's value scales with cluster size.
