IstioOperator Options

11 minute read

Configuration affecting Istio control plane installation version and shape.

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.

Field	Type	Description	Required
`profile`	`string`	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.	No
`installPackagePath`	`string`	Path for the install package. e.g. - /tmp/istio-installer/nightly (local file path)	No
`hub`	`string`	Root for docker image paths e.g. docker.io/istio	No
`tag`	`TypeInterface`	Version tag for docker images e.g. 1.0.6	No
`namespace`	`string`	Namespace to install control plane resources into. If unset, Istio will be installed into the same namespace as the IstioOperator CR.	No
`revision`	`string`	Identify the revision this installation is associated with. This option is currently experimental.	No
`meshConfig`	`TypeMapStringInterface`	Config used by control plane components internally.	No
`components`	`IstioComponentSetSpec`	Kubernetes resource settings, enablement and component-specific settings that are not internal to the component.	No
`addonComponents`	`map<string, ExternalComponentSpec>`	Extra addon components which are not explicitly specified above.	No
`values`	`TypeMapStringInterface`	Overrides for default values.yaml. This is a validated pass-through to Helm templates. See the Helm installation options for schema details: https://istio.io/docs/reference/config/installation-options/. Anything that is available in IstioOperatorSpec should be set above rather than using the passthrough. This includes Kubernetes resource settings for components in KubernetesResourcesSpec.	No
`unvalidatedValues`	`TypeMapStringInterface`	Unvalidated overrides for default values.yaml. Used for custom templates where new parameters are added.	No

InstallStatus

Observed state of IstioOperator

Field	Type	Description	Required
`status`	`Status`	Overall status of all components controlled by the operator. - If all components have status NONE, overall status is NONE. - If all components are HEALTHY, overall status is HEALTHY. - If one or more components are RECONCILING and others are HEALTHY, overall status is RECONCILING. - If one or more components are UPDATING and others are HEALTHY, overall status is UPDATING. - If components are a mix of RECONCILING, UPDATING and HEALTHY, overall status is UPDATING. - If any component is in ERROR state, overall status is ERROR.	No
`componentStatus`	`map<string, VersionStatus>`	Individual status of each component controlled by the operator. The map key is the name of the component.	No

Field	Type	Description	Required
`path`	`string`	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

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.

Field	Type	Description	Required
`matchLabels`	`map<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
`matchExpressions`	`LabelSelectorRequirement[]`	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.
