Struct LinuxNodeConfig 

pub struct LinuxNodeConfig {
    pub cgroup_mode: Option<String>,
    pub hugepages: Option<HugepagesConfig>,
    pub node_kernel_module_loading: Option<NodeKernelModuleLoading>,
    pub sysctls: Option<HashMap<String, String>>,
    pub transparent_hugepage_defrag: Option<String>,
    pub transparent_hugepage_enabled: Option<String>,
}

Parameters that can be configured on Linux nodes.

This type is not used in any activity, and only used as part of another schema.

Fields

cgroup_mode: Option<String>

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

hugepages: Option<HugepagesConfig>

Optional. Amounts for 2M and 1G hugepages

node_kernel_module_loading: Option<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.

sysctls: Option<HashMap<String, String>>

The Linux kernel parameters to be applied to the nodes and all pods running on the nodes. The following parameters are supported. net.core.busy_poll net.core.busy_read net.core.netdev_max_backlog net.core.rmem_max net.core.rmem_default net.core.wmem_default net.core.wmem_max net.core.optmem_max net.core.somaxconn net.ipv4.tcp_rmem net.ipv4.tcp_wmem net.ipv4.tcp_tw_reuse net.ipv4.tcp_mtu_probing net.ipv4.tcp_max_orphans net.ipv4.tcp_max_tw_buckets net.ipv4.tcp_syn_retries net.ipv4.tcp_ecn net.ipv4.tcp_congestion_control net.netfilter.nf_conntrack_max net.netfilter.nf_conntrack_buckets net.netfilter.nf_conntrack_tcp_timeout_close_wait net.netfilter.nf_conntrack_tcp_timeout_time_wait net.netfilter.nf_conntrack_tcp_timeout_established net.netfilter.nf_conntrack_acct kernel.shmmni kernel.shmmax kernel.shmall kernel.perf_event_paranoid kernel.sched_rt_runtime_us kernel.softlockup_panic kernel.yama.ptrace_scope kernel.kptr_restrict kernel.dmesg_restrict kernel.sysrq fs.aio-max-nr fs.file-max fs.inotify.max_user_instances fs.inotify.max_user_watches fs.nr_open vm.dirty_background_ratio vm.dirty_background_bytes vm.dirty_expire_centisecs vm.dirty_ratio vm.dirty_bytes vm.dirty_writeback_centisecs vm.max_map_count vm.overcommit_memory vm.overcommit_ratio vm.vfs_cache_pressure vm.swappiness vm.watermark_scale_factor vm.min_free_kbytes

transparent_hugepage_defrag: Option<String>

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.

transparent_hugepage_enabled: Option<String>

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.
