Installing the Operators

To install Red Hat OpenShift Service Mesh, first install the required Operators on OpenShift Container Platform and then create a ServiceMeshControlPlane resource to deploy the control plane.

This basic installation is configured based on the default OpenShift settings and is not designed for production use.  Use this default installation to verify your installation, and then configure your service mesh for your specific environment.
Prerequisites

The following steps show how to install a basic instance of Red Hat OpenShift Service Mesh on OpenShift Container Platform.

Operator overview

Red Hat OpenShift Service Mesh requires the following four Operators:

  • OpenShift Elasticsearch - (Optional) Provides database storage for tracing and logging with the distributed tracing platform. It is based on the open source Elasticsearch project.

  • Red Hat OpenShift distributed tracing platform - Provides distributed tracing to monitor and troubleshoot transactions in complex distributed systems. It is based on the open source Jaeger project.

  • Kiali - Provides observability for your service mesh. Allows you to view configurations, monitor traffic, and analyze traces in a single console. It is based on the open source Kiali project.

  • Red Hat OpenShift Service Mesh - Allows you to connect, secure, control, and observe the microservices that comprise your applications. The Service Mesh Operator defines and monitors the ServiceMeshControlPlane resources that manage the deployment, updating, and deletion of the Service Mesh components. It is based on the open source Istio project.

Do not install Community versions of the Operators. Community Operators are not supported.

Installing the Operators

To install Red Hat OpenShift Service Mesh, install following Operators in this order. Repeat the procedure for each Operator.

  • OpenShift Elasticsearch

  • Red Hat OpenShift distributed tracing platform

  • Kiali

  • Red Hat OpenShift Service Mesh

If you have already installed the OpenShift Elasticsearch Operator as part of OpenShift Logging, you do not need to install the OpenShift Elasticsearch Operator again. The Red Hat OpenShift distributed tracing platform Operator will create the Elasticsearch instance using the installed OpenShift Elasticsearch Operator.
Procedure

  1. Log in to the OpenShift Container Platform web console as a user with the cluster-admin role. If you use Red Hat OpenShift Dedicated, you must have an account with the dedicated-admin role.

  2. In the OpenShift Container Platform web console, click Operators → OperatorHub.

  3. Type the name of the Operator into the filter box and select the Red Hat version of the Operator. Community versions of the Operators are not supported.

  4. Click Install.

  5. On the Install Operator page for each Operator, accept the default settings.

  6. Click Install. Wait until the Operator has installed before repeating the steps for the next Operator in the list.

    • The OpenShift Elasticsearch Operator is installed in the openshift-operators-redhat namespace and is available for all namespaces in the cluster.

    • The Red Hat OpenShift distributed tracing platform is installed in the openshift-distributed-tracing namespace and is available for all namespaces in the cluster.

    • The Kiali and Red Hat OpenShift Service Mesh Operators are installed in the openshift-operators namespace and are available for all namespaces in the cluster.

  7. After all you have installed all four Operators, click Operators → Installed Operators to verify that your Operators installed.

Next steps

The Red Hat OpenShift Service Mesh Operator does not create the various Service Mesh custom resource definitions (CRDs) until you deploy a Service Mesh control plane. You use the ServiceMeshControlPlane resource to install and configure the Service Mesh components. For more information, see Creating the ServiceMeshControlPlane.
