k8s.io.apimachinery.pkg.apis.meta.v1.LabelSelector

A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.

FieldTypeDescriptionRequired
matchLabelsmap<string, string>

matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is “key”, the operator is “In”, and the values array contains only “value”. The requirements are ANDed. +optional

No
matchExpressionsLabelSelectorRequirement[]

matchExpressions is a list of label selector requirements. The requirements are ANDed. +optional

No

k8s.io.apimachinery.pkg.api.resource.Quantity

Quantity is a fixed-point representation of a number. It provides convenient marshaling/unmarshaling in JSON and YAML, in addition to String() and Int64() accessors.

The serialization format is:

::= (Note that may be empty, from the “” case in .) ::= 0 | 1 | … | 9 ::= | ::= | . | . | . ::= “+” | “-” ::= | ::= | | ::= Ki | Mi | Gi | Ti | Pi | Ei (International System of units; See: http://physics.nist.gov/cuu/Units/binary.html) ::= m | “” | k | M | G | T | P | E (Note that 1024 = 1Ki but 1000 = 1k; I didn’t choose the capitalization.) ::= “e” | “E”

No matter which of the three exponent forms is used, no quantity may represent a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal places. Numbers larger or more precise will be capped or rounded up. (E.g.: 0.1m will rounded up to 1m.) This may be extended in the future if we require larger or smaller quantities.

When a Quantity is parsed from a string, it will remember the type of suffix it had, and will use the same type again when it is serialized.

Before serializing, Quantity will be put in “canonical form”. This means that Exponent/suffix will be adjusted up or down (with a corresponding increase or decrease in Mantissa) such that: a. No precision is lost b. No fractional digits will be emitted c. The exponent (or suffix) is as large as possible. The sign will be omitted unless the number is negative.

Examples: 1.5 will be serialized as “1500m” 1.5Gi will be serialized as “1536Mi”

Note that the quantity will NEVER be internally represented by a floating point number. That is the whole point of this exercise.

Non-canonical values will still parse as long as they are well formed, but will be re-emitted in their canonical form. (So always use canonical form, or don’t diff.)

This format is intended to make it difficult to use these numbers without writing some sort of special handling code in the hopes that that will cause implementors to also use a fixed point implementation.

K8sObjectOverlay.PathValue

FieldTypeDescriptionRequired
pathstring

Path of the form a.[key1:value1].b.[:value2] Where [key1:value1] is a selector for a key-value pair to identify a list element and [:value] is a value selector to identify a list element in a leaf list. All path intermediate nodes must exist.

No

k8s.io.api.core.v1.Toleration

The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>.

FieldTypeDescriptionRequired
keystring

Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. +optional

No
operatorstring

Operator represents a key’s relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. +optional

No
valuestring

Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. +optional

No
effectstring

Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. +optional

No
tolerationSecondsint64

TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. +optional

No

IstioOperatorSpec

IstioOperatorSpec defines the desired installed state of Istio components. The spec is a used to define a customization of the default profile values that are supplied with each Istio release. Because the spec is a customization API, specifying an empty IstioOperatorSpec results in a default Istio component values.

FieldTypeDescriptionRequired
profilestring

Path or name for the profile e.g. - minimal (looks in profiles dir for a file called minimal.yaml) - /tmp/istio/install/values/custom/custom-install.yaml (local file path) default profile is used if this field is unset.

Unvalidated overrides for default values.yaml. Used for custom templates where new parameters are added.

No
