Operator Installation
IstioControlPlane is a schema for both defining and customizing Istio control plane installations. Running the operator with an empty user defined InstallSpec results in an control plane with default values, using the default charts.
The simplest install specialization is to point the user InstallSpec profile to a different values file, for example an Istio minimal control plane, which will use the values associated with the minimal control plane profile for Istio.
Deeper customization is possible at three levels:
New APIs defined in this file
Feature API: this API groups an Istio install by features and allows enabling/disabling the features, selecting base control plane profiles, as well as some additional high level settings that are feature specific. Each feature contains one or more components, which correspond to Istio components (Pods) in the cluster.
k8s API: this API is a pass through to k8s resource settings for Istio k8s resources. It allows customizing Istio k8s resources like Affinity, Resource requests/limits, PodDisruptionBudgetSpec, Selectors etc. in a more consistent and k8s specific way compared to values.yaml. See KubernetesResourcesSpec in this file for details.
values.yaml
The entirety of values.yaml settings is accessible through InstallSpec (see CommonComponentSpec/Values). This API will gradually be deprecated and values there will be moved either into CRDs that are used to directly configure components or, in the case of k8s settings, will be replaced by the new API above.
k8s resource overlays
Once a manifest is rendered from InstallSpec, a further customization can be applied by specifying k8s resource overlays. The concept is similar to kustomize, where JSON patches are applied for object paths. This allows customization at the lowest level and eliminates the need to create ad-hoc template parameters, or edit templates.
Here are a few example uses:

k8s.io.api.autoscaling.v2beta1.HorizontalPodAutoscalerSpec
HorizontalPodAutoscalerSpec describes the desired functionality of the HorizontalPodAutoscaler.
Field | Type | Description | Required |
---|---|---|---|
scaleTargetRef | CrossVersionObjectReference | scaleTargetRef points to the target resource to scale, and is used to the pods for which metrics should be collected, as well as to actually change the replica count. | No |
minReplicas | int32 | minReplicas is the lower limit for the number of replicas to which the autoscaler can scale down. It defaults to 1 pod. minReplicas is allowed to be 0 if the alpha feature gate HPAScaleToZero is enabled and at least one Object or External metric is configured. Scaling is active as long as at least one metric value is available. +optional | No |
maxReplicas | int32 | maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up. It cannot be less that minReplicas. | No |
metrics | MetricSpec[] | metrics contains the specifications for which to use to calculate the desired replica count (the maximum replica count across all metrics will be used). The desired replica count is calculated multiplying the ratio between the target value and the current value by the current number of pods. Ergo, metrics used must decrease as the pod count is increased, and vice-versa. See the individual metric source types for more information about how each type of metric must respond. +optional | No |
k8s.io.api.core.v1.Affinity
Affinity is a group of affinity scheduling rules.
Field | Type | Description | Required |
---|---|---|---|
nodeAffinity | NodeAffinity | Describes node affinity scheduling rules for the pod. +optional | No |

podAntiAffinity | PodAntiAffinity | Describes pod anti-affinity scheduling rules (e.g. avoid putting this pod in the same node, zone, etc. as some other pod(s)). +optional | No |
k8s.io.api.core.v1.EnvVar
EnvVar represents an environment variable present in a Container.
Field | Type | Description | Required |
---|---|---|---|
name | string | Name of the environment variable. Must be a C_IDENTIFIER. | No |
value | string | Variable references $(VARNAME) are expanded using the previous defined environment variables in the container and any service environment variables. If a variable cannot be resolved, the reference in the input string will be unchanged. The $(VARNAME) syntax can be escaped with a double $$, ie: $$(VAR_NAME). Escaped references will never be expanded, regardless of whether the variable exists or not. Defaults to “”. +optional | No |
valueFrom | EnvVarSource | Source for the environment variable’s value. Cannot be used if value is not empty. +optional | No |
k8s.io.api.core.v1.ServiceSpec
ServiceSpec describes the attributes that a user creates on a service.
Field | Type | Description | Required |
---|---|---|---|
ports | ServicePort[] | The list of ports that are exposed by this service. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies +patchMergeKey=port +patchStrategy=merge +listType=map +listMapKey=port +listMapKey=protocol | No |
selector | map<string, string> | Route service traffic to pods with label keys and values matching this selector. If empty or not present, the service is assumed to have an external process managing its endpoints, which Kubernetes will not modify. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/ +optional | No |
clusterIP | string | clusterIP is the IP address of the service and is usually assigned randomly by the master. If an address is specified manually and is not in use by others, it will be allocated to the service; otherwise, creation of the service will fail. This field can not be changed through updates. Valid values are “None”, empty string (“”), or a valid IP address. “None” can be specified for headless services when proxying is not required. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies +optional | No |
type | string | type determines how the Service is exposed. Defaults to ClusterIP. Valid options are ExternalName, ClusterIP, NodePort, and LoadBalancer. “ExternalName” maps to the specified externalName. “ClusterIP” allocates a cluster-internal IP address for load-balancing to endpoints. Endpoints are determined by the selector or if that is not specified, by manual construction of an Endpoints object. If clusterIP is “None”, no virtual IP is allocated and the endpoints are published as a set of endpoints rather than a stable IP. “NodePort” builds on ClusterIP and allocates a port on every node which routes to the clusterIP. “LoadBalancer” builds on NodePort and creates an external load-balancer (if supported in the current cloud) which routes to the clusterIP. More info: https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types +optional | No |
externalIPs | string[] | externalIPs is a list of IP addresses for which nodes in the cluster will also accept traffic for this service. These IPs are not managed by Kubernetes. The user is responsible for ensuring that traffic arrives at a node with this IP. A common example is external load-balancers that are not part of the Kubernetes system. +optional | No |
sessionAffinity | string | Supports “ClientIP” and “None”. Used to maintain session affinity. Enable client IP based session affinity. Must be ClientIP or None. Defaults to None. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies +optional | No |
loadBalancerIP | string | Only applies to Service Type: LoadBalancer LoadBalancer will get created with the IP specified in this field. This feature depends on whether the underlying cloud-provider supports specifying the loadBalancerIP when a load balancer is created. This field will be ignored if the cloud-provider does not support the feature. +optional | No |
loadBalancerSourceRanges | string[] | If specified and supported by the platform, this will restrict traffic through the cloud-provider load-balancer will be restricted to the specified client IPs. This field will be ignored if the cloud-provider does not support the feature.” More info: https://kubernetes.io/docs/tasks/access-application-cluster/configure-cloud-provider-firewall/ +optional | No |
externalName | string | externalName is the external reference that kubedns or equivalent will return as a CNAME record for this service. No proxying will be involved. Must be a valid RFC-1123 hostname (https://tools.ietf.org/html/rfc1123) and requires Type to be ExternalName. +optional | No |
externalTrafficPolicy | string | externalTrafficPolicy denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints. “Local” preserves the client source IP and avoids a second hop for LoadBalancer and Nodeport type services, but risks potentially imbalanced traffic spreading. “Cluster” obscures the client source IP and may cause a second hop to another node, but should have good overall load-spreading. +optional | No |
healthCheckNodePort | int32 | healthCheckNodePort specifies the healthcheck nodePort for the service. If not specified, HealthCheckNodePort is created by the service api backend with the allocated nodePort. Will use user-specified nodePort value if specified by the client. Only effects when Type is set to LoadBalancer and ExternalTrafficPolicy is set to Local. +optional | No |
publishNotReadyAddresses | bool | publishNotReadyAddresses, when set to true, indicates that DNS implementations must publish the notReadyAddresses of subsets for the Endpoints associated with the Service. The default value is false. The primary use case for setting this field is to use a StatefulSet’s Headless Service to propagate SRV records for its Pods without respect to their readiness for purpose of peer discovery. +optional | No |
sessionAffinityConfig | SessionAffinityConfig | sessionAffinityConfig contains the configurations of session affinity. +optional | No |
ipFamily | string | ipFamily specifies whether this Service has a preference for a particular IP family (e.g. IPv4 vs. IPv6). If a specific IP family is requested, the clusterIP field will be allocated from that family, if it is available in the cluster. If no IP family is requested, the cluster’s primary IP family will be used. Other IP fields (loadBalancerIP, loadBalancerSourceRanges, externalIPs) and controllers which allocate external load-balancers should use the same IP family. Endpoints for this Service will be of this family. This field is immutable after creation. Assigning a ServiceIPFamily not available in the cluster (e.g. IPv6 in IPv4 only cluster) is an error condition and will fail during clusterIP assignment. +optional | 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>.
Field | Type | Description | Required |
---|---|---|---|
key | string | 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 |
operator | string | 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 |
value | string | 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 |
effect | string | Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. +optional | No |
tolerationSeconds | int64 | 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 |
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.
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 |
