IstioOperator Options

Configuration affecting Istio control plane installation version and shape. Note: unlike other Istio protos, field names must use camelCase. This is asserted in tests. Without camelCase, the json tag on the Go struct will not match the user’s JSON representation. This leads to Kubernetes merge libraries, which rely on this tag, to fail. All other usages use jsonpb which does not use the json tag.

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.

apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
spec:
  profile: default
  hub: gcr.io/istio-testing
  tag: latest
  revision: 1-8-0
  meshConfig:
    accessLogFile: /dev/stdout
    enableTracing: true
  components:
    egressGateways:
    - name: istio-egressgateway
      enabled: true
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.

No

  • /tmp/istio-installer/nightly (local file path)
No
hubstring

No
namespacestring

Namespace to install control plane resources into. If unset, Istio will be installed into the same namespace as the IstioOperator CR. You must also set values.global.istioNamespace if you wish to install Istio in a custom namespace. If you have enabled CNI, you must exclude this namespace by adding it to the list values.cni.excludeNamespaces.

No
revisionstring

Identify the revision this installation is associated with. This option is currently experimental.

No
compatibilityVersionstring

Compatibility version allows configuring Istio to behave like an older version by tuning various settings to align with a previous versions defaults. This accepts a major.minor format, such as 1.23. This option is currently experimental.

No
meshConfigStruct

Config used by control plane components internally.

No
componentsIstioComponentSetSpec

No
valuesStruct

Overrides for default values.yaml. This is a validated pass-through to Helm templates. See the Helm installation options for schema details. 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
unvalidatedValuesStruct

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

No
addonComponentsmap<string, ExternalComponentSpec>

Deprecated. Users should manage the installation of addon components on their own. Refer to samples/addons for demo installation of addon components.

No

InstallStatus

FieldTypeDescriptionRequired
statusStatus

Overall status of all components controlled by the operator.

  • 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.
  • If further action is needed for reconciliation to proceed, overall status is ACTION_REQUIRED.

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
valueValue

Value to add, delete or replace. For add, the path should be a new leaf. For delete, value should be unset. For replace, path should reference an existing node. All values are strings but are converted into appropriate type based on schema.

No

google.protobuf.Value

Value represents a dynamically typed value which can be either null, a number, a string, a boolean, a recursive struct value, or a list of values. A producer of value is expected to set one of that variants, absence of any variant indicates an error.

The JSON representation for Value is JSON value.

No
subPathstring

Path within the volume from which the container’s volume should be mounted. Defaults to "" (volume’s root).

No

mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10.

No
subPathExprstring

Expanded path within the volume from which the container’s volume should be mounted. Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container’s environment. Defaults to "" (volume’s root). SubPathExpr and SubPath are mutually exclusive.

No

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.

No
matchExpressionsLabelSelectorRequirement[]

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

RECONCILING

Controller has started but not yet completed reconciliation loop for the component.

HEALTHY

Component is healthy.

ERROR

Component is in an error state.

ACTION_REQUIRED

Overall status only and would not be set as a component status. Action is needed from the user for reconciliation to proceed e.g. There are proxies still pointing to the control plane revision when try to remove an IstioOperator CR.
