AWS EKS托管节点组自定义AMI支持：无法通过包含bootstrap.sh的YAML配置文件创建节点组

Let's break down the issue and fix it step by step:

Root Cause #

The error you're seeing is a YAML syntax parsing failure at line 15. This typically happens when YAML misinterprets part of your content as a key-value mapping when it shouldn't. In your case, the problem stems from the double quotes wrapping the --kubelet-extra-args parameter in the overrideBootstrapCommand block. The parameter string contains multiple colons that YAML tries to treat as mapping separators, triggering the parsing error.

Also, double-check that you're using spaces for indentation (not tabs) in your YAML file—tabs are invalid in YAML and often cause unexpected parsing issues.

Solution #

Modify the overrideBootstrapCommand to use single quotes for the --kubelet-extra-args parameter instead of double quotes. This avoids YAML parsing conflicts while still working correctly in bash. Here's the corrected YAML file:

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
  name: ginny
  region: us-west-2
  version: '1.17'
managedNodeGroups:
- name: ginny-mng-custom-ami
  instanceType: t3.small
  desiredCapacity: 2
  labels: {role: worker}
  ami: ami-0030109261aa0205b
  ssh:
    publicKeyName: bastion
  preBootstrapCommands:
  - kubelet --version > /etc/eks/test-preBootstrapCommands
  overrideBootstrapCommand: |
    #!/bin/bash
    set -ex
    /etc/eks/bootstrap.sh ginny --kubelet-extra-args '--node-labels=alpha.eksctl.io/cluster-name=ginny,alpha.eksctl.io/nodegroup-name=ginny-mng-custom-ami,eks.amazonaws.com/nodegroup=ginny-mng-custom-ami,eks.amazonaws.com/nodegroup-image=ami-0030109261aa0205b'

Verification Steps #

1. Save the corrected YAML file (note: you had a typo in the filename maanged-nodegroup.yaml—make sure it's managed-nodegroup.yaml when running the command).
2. Re-run your eksctl command:

   eksctl create nodegroup --config-file managed-nodegroup.yaml
   

3. Check the node group creation progress with:

   eksctl get nodegroups --cluster ginny
   

This change ensures YAML parses the bootstrap command correctly, and the single quotes will be handled properly by bash when executing the bootstrap script.
