Summary

Fixes #1807

The documentation in the Graviton scheduling section incorrectly referenced a tainted=yes label when the actual nodeSelector in the manifest uses kubernetes.io/arch=arm64.

Problem

The documentation contained two incorrect references:

  1. Line 35: "We have pre-configured our tainted managed node group with a label of tainted=yes..."

    • But the manifest actually uses kubernetes.io/arch: arm64
  2. Line 88: "We can see that we have pinned the pod to any node with the tainted=yes label..."

    • But the pod was actually pinned to kubernetes.io/arch=arm64

This was confusing for users following the tutorial because the explanation didn't match the actual code.

Fix

Updated the explanations to correctly reference the kubernetes.io/arch=arm64 label that is actually used in the Kustomize patches and kubectl output.

Testing

  • Verified the manifest files use kubernetes.io/arch: arm64 as the nodeSelector
  • Confirmed the kubectl output in the docs shows kubernetes.io/arch=arm64
  • Documentation now matches the actual implementation

The documentation incorrectly referenced `tainted=yes` label when
the actual nodeSelector uses `kubernetes.io/arch=arm64`. This was
confusing because:

1. Line 35 mentioned "tainted=yes" but the manifest uses
   "kubernetes.io/arch: arm64"
2. Line 88 said the pod was pinned to "tainted=yes" but it was
   actually pinned to "kubernetes.io/arch=arm64"

Updated the explanations to correctly reference the ARM64
architecture label that is actually used in the examples.

Fixes aws-samples#1807
