kubelet_extra_args cannot be specified in bootstrap_env

[mustafa89]

Description

I've been trying to use the KUBELET_EXTRA_ARGS in the bootstrap_env map in order to set taints but it was not working. After some digging I see that the default user_data always sets this value therefore the exported env var is never read.

SEE:

/etc/eks/bootstrap.sh ${cluster_name} --kubelet-extra-args <node-lables + taints + default labels> --apiserver-endpoint "$${API_SERVER_URL}" --b64-cluster-ca "$${B64_CLUSTER_CA}"

I think this should be mentioned in the README or Input descriptions. Currently, it implies all arguments to the bootstrap.sh script can be defined within in the bootstrap_env map.

⚠️ Note

Not using a custom AMI.

Versions

• Terraform: 0.13.6
• Provider(s): AWS: 3.63.0
• Module: 17.23.0

Reproduction

Add the below bootstrap_env key-value to a node group definition. The value will not be propagated.

Code Snippet to Reproduce

bootstrap_env = {
          KUBELET_EXTRA_ARGS = "--register-with-taints=dedicated=TEST:NoSchedule"
}

Expected behavior

AFAIS, KUBELET_EXTRA_ARGS is not supported in bootstrap_env

luckily stumbled upon: #1717 (comment)

I feel this point # 1 should really be mentioned in the docs some where.
