Struct LinuxNodeConfig

#[non_exhaustive]
pub struct LinuxNodeConfig {
    pub sysctls: HashMap<String, String>,
    pub cgroup_mode: CgroupMode,
    pub hugepages: Option<HugepagesConfig>,
}

Parameters that can be configured on Linux nodes.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

sysctls: 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.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 kernel.shmmni kernel.shmmax kernel.shmall

cgroup_mode: CgroupMode

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

hugepages: Option<HugepagesConfig>

Optional. Amounts for 2M and 1G hugepages

Implementations

impl LinuxNodeConfig

pub fn set_cgroup_mode<T: Into<CgroupMode>>(self, v: T) -> Self

Sets the value of cgroup_mode.

pub fn set_hugepages<T: Into<Option<HugepagesConfig>>>(self, v: T) -> Self

Sets the value of hugepages.

pub fn set_sysctls<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Sets the value of sysctls.

Trait Implementations

impl Clone for LinuxNodeConfig

fn clone(&self) -> LinuxNodeConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinuxNodeConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LinuxNodeConfig

fn default() -> LinuxNodeConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LinuxNodeConfig

where LinuxNodeConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for LinuxNodeConfig

fn typename() -> &'static str

The typename of this message.

impl PartialEq for LinuxNodeConfig

fn eq(&self, other: &LinuxNodeConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LinuxNodeConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
