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.neigh.default.gc_thresh1 net.ipv4.neigh.default.gc_thresh2 net.ipv4.neigh.default.gc_thresh3 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.keys.maxkeys kernel.keys.maxbytes 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
cgroup_mode google.cloud.container_v1beta1.types.LinuxNodeConfig.CgroupMode
cgroup_mode specifies the cgroup mode to be used on the node.
hugepages google.cloud.container_v1beta1.types.LinuxNodeConfig.HugepagesConfig
Optional. Amounts for 2M and 1G hugepages This field is a member of oneof_ _hugepages.
transparent_hugepage_enabled google.cloud.container_v1beta1.types.LinuxNodeConfig.TransparentHugepageEnabled
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 google.cloud.container_v1beta1.types.LinuxNodeConfig.TransparentHugepageDefrag
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 google.cloud.container_v1beta1.types.LinuxNodeConfig.CustomNodeInit
Optional. Allow users to run arbitrary bash script or container on the node.
swap_config google.cloud.container_v1beta1.types.LinuxNodeConfig.SwapConfig
Optional. Enables and configures swap space on nodes. If omitted, swap is disabled. This field is a member of oneof_ _swap_config.
node_kernel_module_loading google.cloud.container_v1beta1.types.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 google.cloud.container_v1beta1.types.LinuxNodeConfig.AccurateTimeConfig
Optional. The accurate time configuration for the node pool. This field is a member of oneof_ _accurate_time_config.

Classes

AccurateTimeConfig

AccurateTimeConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

CgroupMode

CgroupMode(value)

Possible cgroup modes that can be used.

CustomNodeInit

CustomNodeInit(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Support for running custom init code while bootstrapping nodes.

NodeKernelModuleLoading

NodeKernelModuleLoading(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Configuration for kernel module loading on nodes.

SwapConfig

SwapConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.
