Struct NodeAffinity

pub struct NodeAffinity {
    pub preferred_during_scheduling_ignored_during_execution: Option<Vec<PreferredSchedulingTerm>>,
    pub required_during_scheduling_ignored_during_execution: Option<NodeSelector>,
}

Node affinity is a group of node affinity scheduling rules.

Fields

preferred_during_scheduling_ignored_during_execution: Option<Vec<PreferredSchedulingTerm>>

The scheduler will prefer to schedule pods to nodes that satisfy the affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding “weight” to the sum if the node matches the corresponding matchExpressions; the node(s) with the highest sum are the most preferred.

required_during_scheduling_ignored_during_execution: Option<NodeSelector>

If the affinity requirements specified by this field are not met at scheduling time, the pod will not be scheduled onto the node. If the affinity requirements specified by this field cease to be met at some point during pod execution (e.g. due to an update), the system may or may not try to eventually evict the pod from its node.

Trait Implementations

impl Clone for NodeAffinity

fn clone(&self) -> NodeAffinity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeAffinity

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

Formats the value using the given formatter.

impl DeepMerge for NodeAffinity

fn merge_from(&mut self, other: Self)

Merge other into self.

impl Default for NodeAffinity

fn default() -> NodeAffinity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NodeAffinity

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NodeAffinity

fn eq(&self, other: &NodeAffinity) -> 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 NodeAffinity

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
