    caFile [Required]
    string    		Trusted root certificates for server
    certData [Required]
    []byte    		CertData holds PEM-encoded bytes (typically read from a client certificate file). CertData takes precedence over CertFile
    keyData [Required]
    []byte    		KeyData holds PEM-encoded bytes (typically read from a client certificate key file). KeyData takes precedence over KeyFile
    caData [Required]
    []byte    		CAData holds PEM-encoded bytes (typically read from a root certificates bundle). CAData takes precedence over CAFile

    LabelPreference

    Appears in:

    LabelPreference holds the parameters that are used to configure the corresponding priority function

    FieldDescription
    label [Required]
    string    		Used to identify node “groups”
    presence [Required]
    bool    		This is a boolean flag If true, higher priority is given to nodes that have the label If false, higher priority is given to nodes that do not have the label

    LabelsPresence holds the parameters that are used to configure the corresponding predicate in scheduler policy configuration.

    FieldDescription
    labels [Required]
    []string    		The list of labels that identify node “groups” All of the labels should be either present (or absent) for the node to be considered a fit for hosting the pod
    presence [Required]
    bool    		The boolean flag that indicates whether the labels should be present or absent from the node

    LegacyExtender

    Appears in:

    LegacyExtender holds the parameters used to communicate with the extender. If a verb is unspecified/empty, it is assumed that the extender chose not to provide that extension.

    PredicateArgument

    Appears in:

    PredicateArgument represents the arguments to configure predicate functions in scheduler policy configuration. Only one of its members may be specified

    FieldDescription
    serviceAffinity [Required]
    ServiceAffinity    		The predicate that provides affinity for pods belonging to a service It uses a label to identify nodes that belong to the same “group”
    labelsPresence [Required]
    		The predicate that checks whether a particular node has a certain label defined or not, regardless of value

    PredicatePolicy

    Appears in:

    PredicatePolicy describes a struct of a predicate policy.

    FieldDescription
    name [Required]
    string    		Identifier of the predicate policy For a custom predicate, the name can be user-defined For the Kubernetes provided predicates, the name is the identifier of the pre-defined predicate
    argument [Required]
    PredicateArgument    		Holds the parameters to configure the given predicate

    PriorityArgument

    Appears in:

    PriorityArgument represents the arguments to configure priority functions in scheduler policy configuration. Only one of its members may be specified

    FieldDescription
    serviceAntiAffinity [Required]
    		The priority function that ensures a good spread (anti-affinity) for pods belonging to a service It uses a label to identify nodes that belong to the same “group”
    labelPreference [Required]
    LabelPreference    		The priority function that checks whether a particular node has a certain label defined or not, regardless of value
    requestedToCapacityRatioArguments [Required]
    		The RequestedToCapacityRatio priority function is parametrized with function shape.

    Appears in:

    FieldDescription
    name [Required]
    string    		Identifier of the priority policy For a custom priority, the name can be user-defined For the Kubernetes provided priority functions, the name is the identifier of the pre-defined priority function
    weight [Required]
    int64    		The numeric multiplier for the node scores that the priority function generates The weight should be non-zero and can be a positive or a negative integer
    argument [Required]
    		Holds the parameters to configure the given priority function

    RequestedToCapacityRatioArguments

    Appears in:

    RequestedToCapacityRatioArguments holds arguments specific to RequestedToCapacityRatio priority function.

    ResourceSpec

    Appears in:
