Struct TopologySpreadConstraint 

pub struct TopologySpreadConstraint {
    pub label_selector: Option<LabelSelector>,
    pub max_skew: Option<i32>,
    pub topology_key: Option<String>,
    pub when_unsatisfiable: Option<String>,
}

Fields

label_selector: Option<LabelSelector>

max_skew: Option<i32>

MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 1/1/0: +—––+—––+—––+ zone1 | zone2 | zone3 | +—––+—––+—––+ P | P | | +—––+—––+—––+ if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 1/1/1; scheduling it onto zone1(zone2) would make the ActualSkew(2-0) on zone1(zone2) violate MaxSkew(1). if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It’s a required field. Default value is 1 and 0 is not allowed.

topology_key: Option<String>

TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. It’s a required field.

when_unsatisfiable: Option<String>

Trait Implementations

impl Clone for TopologySpreadConstraint

fn clone(&self) -> TopologySpreadConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopologySpreadConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TopologySpreadConstraint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for TopologySpreadConstraint

Converts Query Parameters representation (style=form, explode=false) to a TopologySpreadConstraint value as specified in https://swagger.io/docs/specification/serialization/ Should be implemented in a serde deserializer

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for TopologySpreadConstraint

fn eq(&self, other: &TopologySpreadConstraint) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToString for TopologySpreadConstraint

Converts the TopologySpreadConstraint value to the Query Parameters representation (style=form, explode=false) specified in https://swagger.io/docs/specification/serialization/ Should be implemented in a serde serializer

fn to_string(&self) -> String

Converts the given value to a String.

impl Validate for TopologySpreadConstraint

fn validate(&self) -> Result<(), ValidationErrors>

impl<'v_a> ValidateArgs<'v_a> for TopologySpreadConstraint
