Hi @ecerulm,
This is already being supported kubeletConfiguration.cpuCFSQuota.

@jigisha620 , the documentation at https://karpenter.sh/docs/concepts/nodeclasses/ explicitly say

Warning:
The Bottlerocket AMIFamily does not support the following fields:

evictionSoft
evictionSoftGracePeriod
evictionMaxPodGracePeriod
cpuCFSQuota

If any of these fields are specified on a Bottlerocket EC2NodeClass, they will be ommited from generated UserData and ignored for scheduling purposes. Support for these fields can be tracked via GitHub issue #3722.

That section of the documentation was added 4 days ago on #6720, if it's not accurate and kubeletConfiguration.cpuCFSQuota is actually supported in (1.0.0) then we should change the documentation. If it's not yet supported in 1.0.0 but it's supported in "main" then perfect and you can close this issue.

In any case this is related to #4271 and #3722

@ecerulm , thanks for pointing this out. I will go ahead and update the documentation since the change to support this field was merged - #4260
