Node pool

As explained in Effective Platform Engineering

A node pool is a managed group of compute nodes sharing a configuration and available for scheduling workloads.

How Effective Platform Engineering covers it

How deep it goes

Explains labels, affinity, taints, tolerations, and provisioning tests, but stops short of Karpenter implementation internals.

Examples

Tests AMD and ARM deployments, management-node affinity, dedicated tolerations, pod startup, and dynamic node creation.

What it assumes

Assumes Kubernetes workload and scheduling familiarity while demonstrating placement constraints through concrete pod manifests.

What you can do after

Operate/configure workload placement by assigning selectors, affinity, taints, and tolerations, then validate provisioned pools with Bats tests.

How it connects

Connects node pools to Kubernetes scheduling, node affinity, taints, tolerations, Karpenter, and workload placement.
