Custom Features - Service Mesh 1.x | service mesh (2023)

When the Service Mesh operator createsServiceMeshControlPlaneThe resource can also create resources for distributed tracing. Service Mesh uses Jaeger for distributed discovery.

You can specify the Jaeger configuration in two ways:

  • jaeger configuration iServiceMeshControlPlaneresource. There are some limitations with this approach.

  • Configure Jaeger in a customjaegerfeature and then referring to the Jaeger example atServiceMeshControlPlaneresource. If a Jaeger resource matches its valuenameexists, the control layer will use the existing installation. This approach allows you to fully customize your Jaeger configuration.

The default Jaeger parameters specified inServiceMeshControlPlaneThe following is:

Elasticsearch is a memory intensive application. The initial set of nodes specified in the default installation of OpenShift Container Platform might not be large enough to support the Elasticsearch cluster. You must modify the default Elasticsearch configuration to match the use case and requested features for your OpenShift Container Platform installation. You can adjust CPU and memory limits for each component by modifying the resource block with valid CPU and memory values. Additional nodes must be added to the cluster if you want to run with the recommended amount (or more) of memory. Make sure you do not exceed the required resources for installing OpenShift Container Platform.

Connects to an existing Jaeger instance

In order for SMCP to connect to an existing Jaeger instance, the following must be true:

(Video) Service Mesh Architectures Explained - Sidecar and Beyond - Manuel Zapf, Containous

  • The Jaeger instance is implemented in the same namespace as the control plane, for example inweb systemnamespace.

  • To enable secure communication between services, enable the oauth proxy that secures communication with your Jaeger instance and make sure the secret is set for your Jaeger instance so that Kiali can communicate with it.

  • To use a custom or pre-existing Jaeger instance, click herespec.istio.tracing.enabledto "false" to disable the deployment of a Jaeger instance.

  • Give the mixer the correct jaeger sink endpoint with the settingspec.istio.global.tracer.zipkin.addressin the hostname and port of the jaeger-collector service. Service hostname is normal-collector..svc.cluster.local.

  • Provide correct jaeger query endpoint for Kiali to collect configuration tracesspec.istio.kiali.jaegerInClusterURLin the jaeger-query service hostname - the port is usually not needed as it uses 443 by default. Service hostname is normal-request..svc.cluster.local.

  • Enter the control panel URL for your instance of Jaeger on Kiali to allow access to Jaeger via the Kiali console. You can retrieve the OpenShift path URL generated by the Jaeger operator. If your Jaeger resource is calledoutside hunterand lives inweb systemproject, you can get the path using the following command:

    $ and get route-nthis system exterior jaeger

    sample output

    NAME ΥΠΗΡΕΣΙΕΣ HOST/PORT PATH [...]external-jaeger external-jaeger-istio-system.apps.test external-jaeger-query [...]
