↳ cgroup_mode
int

cgroup_mode specifies the cgroup mode to be used on the node.

↳ hugepages
LinuxNodeConfig\HugepagesConfig

Optional. Amounts for 2M and 1G hugepages

↳ transparent_hugepage_enabled
int

Optional. Transparent hugepage support for anonymous memory can be entirely disabled (mostly for debugging purposes) or only enabled inside MADV_HUGEPAGE regions (to avoid the risk of consuming more memory resources) or enabled system wide. See https://docs.kernel.org/admin-guide/mm/transhuge.html for more details.

↳ transparent_hugepage_defrag
int

Optional. Defines the transparent hugepage defrag configuration on the node. VM hugepage allocation can be managed by either limiting defragmentation for delayed allocation or skipping it entirely for immediate allocation only. See https://docs.kernel.org/admin-guide/mm/transhuge.html for more details.

↳ custom_node_init
LinuxNodeConfig\CustomNodeInit

Optional. Allow users to run arbitrary bash script or container on the node.

LinuxNodeConfig\SwapConfig

Optional. Enables and configures swap space on nodes. If omitted, swap is disabled.

↳ node_kernel_module_loading
LinuxNodeConfig\NodeKernelModuleLoading

Optional. Configuration for kernel module loading on nodes. When enabled, the node pool will be provisioned with a Container-Optimized OS image that enforces kernel module signature verification.

↳ accurate_time_config
LinuxNodeConfig\AccurateTimeConfig

Optional. The accurate time configuration for the node pool.
