    /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"

Error: couldn't create node group filter from command line options: loading config file "maanged-nodegroup.yaml": error converting YAML to JSON: yaml: line 15: mapping values are not allowed in this context

Try this way It should work:

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"
