1.27. Service Mesh control plane configuration reference

You can customize your Red Hat OpenShift Service Mesh by modifying the default ServiceMeshControlPlane (SMCP) resource or by creating a completely custom SMCP resource. This reference section documents the configuration options available for the SMCP resource.

1.27.1. Service Mesh Control plane parameters
링크 복사

The following table lists the top-level parameters for the ServiceMeshControlPlane resource.

표 1.31. ServiceMeshControlPlane resource parameters
NameDescriptionType

apiVersion

APIVersion defines the versioned schema of this representation of an object. Servers convert recognized schemas to the latest internal value, and may reject unrecognized values. The value for the ServiceMeshControlPlane version 2.0 is maistra.io/v2.

The value for ServiceMeshControlPlane version 2.0 is maistra.io/v2.

kind

Kind is a string value that represents the REST resource this object represents.

ServiceMeshControlPlane is the only valid value for a ServiceMeshControlPlane.

metadata

Metadata about this ServiceMeshControlPlane instance. You can provide a name for your Service Mesh control plane installation to keep track of your work, for example, basic.

string

spec

The specification of the desired state of this ServiceMeshControlPlane. This includes the configuration options for all components that comprise the Service Mesh control plane.

For more information, see Table 2.

status

The current status of this ServiceMeshControlPlane and the components that comprise the Service Mesh control plane.

For more information, see Table 3.

The following table lists the specifications for the ServiceMeshControlPlane resource. Changing these parameters configures Red Hat OpenShift Service Mesh components.

표 1.32. ServiceMeshControlPlane resource spec
NameDescriptionConfigurable parameters

addons

The addons parameter configures additional features beyond core Service Mesh control plane components, such as visualization, or metric storage.

3scale, grafana, jaeger, kiali, and prometheus.

cluster

The cluster parameter sets the general configuration of the cluster (cluster name, network name, multi-cluster, mesh expansion, etc.)

meshExpansion, multiCluster, name, and network

gateways

You use the gateways parameter to configure ingress and egress gateways for the mesh.

enabled, additionalEgress, additionalIngress, egress, ingress, and openshiftRoute

general

The general parameter represents general Service Mesh control plane configuration that does not fit anywhere else.

logging and validationMessages

policy

You use the policy parameter to configure policy checking for the Service Mesh control plane. Policy checking can be enabled by setting spec.policy.enabled to true.

mixer remote, or type. type can be set to Istiod, Mixer or None.

profiles

You select the ServiceMeshControlPlane profile to use for default values using the profiles parameter.

default

proxy

You use the proxy parameter to configure the default behavior for sidecars.

accessLogging, adminPort, concurrency, and envoyMetricsService

runtime

You use the runtime parameter to configure the Service Mesh control plane components.

components, and defaults

security

The security parameter allows you to configure aspects of security for the Service Mesh control plane.

certificateAuthority, controlPlane, identity, dataPlane and trust

techPreview

The techPreview parameter enables early access to features that are in technology preview.

N/A

telemetry

If spec.mixer.telemetry.enabled is set to true, telemetry is enabled.

mixer, remote, and type. type can be set to Istiod, Mixer or None.

tracing

You use the tracing parameter to enables distributed tracing for the mesh.

sampling, type. type can be set to Jaeger or None.

version

You use the version parameter to specify what Maistra version of the Service Mesh control plane to install. When creating a ServiceMeshControlPlane with an empty version, the admission webhook sets the version to the current version. New ServiceMeshControlPlanes with an empty version are set to v2.0. Existing ServiceMeshControlPlanes with an empty version keep their setting.

string

ControlPlaneStatus represents the current state of your service mesh.

표 1.33. ServiceMeshControlPlane resource ControlPlaneStatus
NameDescriptionType

annotations

The annotations parameter stores additional, usually redundant status information, such as the number of components deployed by the ServiceMeshControlPlane. These statuses are used by the command-line tool, oc, which does not yet allow counting objects in JSONPath expressions.

Not configurable

conditions

Represents the latest available observations of the object’s current state. Reconciled indicates whether the operator has finished reconciling the actual state of deployed components with the configuration in the ServiceMeshControlPlane resource. Installed indicates whether the Service Mesh control plane has been installed. Ready indicates whether all Service Mesh control plane components are ready.

string

components

Shows the status of each deployed Service Mesh control plane component.

string

appliedSpec

The resulting specification of the configuration options after all profiles have been applied.

ControlPlaneSpec

appliedValues

The resulting values.yaml used to generate the charts.

ControlPlaneSpec

chartVersion

The version of the charts that were last processed for this resource.

string

observedGeneration

The generation observed by the controller during the most recent reconciliation. The information in the status pertains to this particular generation of the object. The status.conditions are not up-to-date if the status.observedGeneration field doesn’t match metadata.generation.

integer

operatorVersion

The version of the operator that last processed this resource.

string

readiness

The readiness status of components & owned resources.

string

This example ServiceMeshControlPlane definition contains all of the supported parameters.
