第 3 章 安装服务 Telemetry Framework 的核心组件

流程

1. 创建一个命名空间来包含 STF 组件，如 service-telemetry ：

   $ oc new-project service-telemetry

2. 在命名空间中创建 OperatorGroup 以便调度 Operator pod：

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1
   kind: OperatorGroup
   metadata:
     name: service-telemetry-operator-group
     namespace: service-telemetry
   spec:
     targetNamespaces:
     - service-telemetry
   EOF

   如需更多信息，请参阅 OperatorGroups。

3. 启用 OperatorHub.io Community Catalog Source 来安装数据存储和视觉化 Operator：

   警告

   红帽支持核心 Operator 和工作负载，包括 AMQ Interconnect、AMQ Certificate Manager、Service Telemetry Operator 和 Smart Gateway Operator。红帽不支持社区 Operator 或工作负载组件，包括 ElasticSearch、Prometheus、Alertmanager、Grafana 以及它们的 Operator。

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1alpha1
   kind: CatalogSource
   metadata:
     name: operatorhubio-operators
     namespace: openshift-marketplace
   spec:
     sourceType: grpc
     image: quay.io/operatorhubio/catalog:latest
     displayName: OperatorHub.io Operators
     publisher: OperatorHub.io
   EOF

4. 使用 redhat-operators CatalogSource 订阅 AMQ Certificate Manager Operator:

   注意

   AMQ 证书管理器部署到 openshift-operators 命名空间，然后可供集群中的所有命名空间使用。因此，在有大量命名空间的集群上，Operator 可能需要几分钟才能在 service-telemetry 命名空间中可用。在将 AMQ Certificate Manager Operator 与其他命名空间范围的 Operator 搭配使用时，AMQ Certificate Manager Operator 与 Operator Lifecycle Manager 的依赖项管理不兼容。

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: amq7-cert-manager-operator
     namespace: openshift-operators
   spec:
     channel: 1.x
     installPlanApproval: Automatic
     name: amq7-cert-manager-operator
     source: redhat-operators
     sourceNamespace: openshift-marketplace
   EOF

5. 验证您的 ClusterServiceVersion。确保 amq7-cert-manager.v1.0.1 的阶段显示为 Succeeded ：

   $ oc get --namespace openshift-operators csv
   
   NAME                       DISPLAY                                         VERSION   REPLACES                   PHASE
   amq7-cert-manager.v1.0.3   Red Hat Integration - AMQ Certificate Manager   1.0.3     amq7-cert-manager.v1.0.2   Succeeded

6. 如果您计划在 ElasticSearch 中存储事件，您必须在 Kubernetes (ECK) Operator 上启用 Elastic Cloud。要启用 ECK Operator，请在 Red Hat OpenShift Container Platform 环境中创建以下清单：

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: elasticsearch-eck-operator-certified
     namespace: service-telemetry
   spec:
     channel: stable
     installPlanApproval: Automatic
     name: elasticsearch-eck-operator-certified
     source: certified-operators
     sourceNamespace: openshift-marketplace
   EOF

7. 验证 Kubernetes Succeeded 上的 Elastic Cloud 的 ClusterServiceVersion:

   $ oc get csv
   
   NAME                                          DISPLAY                        VERSION   REPLACES                                     PHASE
   ...
   elasticsearch-eck-operator-certified.1.9.1   Elasticsearch (ECK) Operator                    1.9.1                                Succeeded
   ...

8. 创建 Smart Gateway Operator 订阅来管理 Smart Gateway 实例：

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: smart-gateway-operator
     namespace: service-telemetry
   spec:
     channel: stable-1.3
     installPlanApproval: Automatic
     name: smart-gateway-operator
     source: redhat-operators
     sourceNamespace: openshift-marketplace
   EOF

9. 创建 Service Telemetry Operator 订阅来管理 STF 实例：

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: service-telemetry-operator
     namespace: service-telemetry
   spec:
     channel: stable-1.3
     installPlanApproval: Automatic
     name: service-telemetry-operator
     source: redhat-operators
     sourceNamespace: openshift-marketplace
   EOF

10. 验证 Service Telemetry Operator 和依赖 Operator：

    $ oc get csv --namespace service-telemetry
    
    NAME                                         DISPLAY                                         VERSION          REPLACES                             PHASE
    amq7-cert-manager.v1.0.3                     Red Hat Integration - AMQ Certificate Manager   1.0.3            amq7-cert-manager.v1.0.2             Succeeded
    amq7-interconnect-operator.v1.10.5           Red Hat Integration - AMQ Interconnect          1.10.5           amq7-interconnect-operator.v1.10.4   Succeeded
    elasticsearch-eck-operator-certified.1.9.1   Elasticsearch (ECK) Operator                    1.9.1                                                 Succeeded
    prometheusoperator.0.47.0                    Prometheus Operator                             0.47.0           prometheusoperator.0.37.0            Succeeded
    service-telemetry-operator.v1.3.1635451892   Service Telemetry Operator                      1.3.1635451892                                        Succeeded
    smart-gateway-operator.v3.0.1635451893       Smart Gateway Operator                          3.0.1635451893                                        Succeeded
