Hi @yaroslav-nakonechnikov, thanks for letting us know about this. I did some digging, and found out that the kubelet requires vm.overcommit_memory
to be set at 1
. The kubelet does allow a more "permissive" mode in which it will warn when this setting, and a few more, don't have the required values. However, in Bottlerocket we configure the more restrictive approach, which will cause the kubelet to refuse to start when the values of the kernel tunables don't match the required values (see kubelet configs -> --protect-kernel-defaults
). What's your use case to require vm.overcommit_memory=0
?

@arnaldo2792 thank you!
we are using splunk, and sometimes it crashes. And as we want to find root cause, we read that: https://docs.splunk.com/Documentation/Splunk/9.2.0/ReleaseNotes/LinuxmemoryovercommittingandSplunkcrashes
and wanted to try it.
yes, we understand that doc is more for on-premise setup, but before submitting case to support, we wanted to try set this setting. And found that it contradicts a bit with documentation
