第 3 章 安装 Service Telemetry Framework 的核心组件

流程

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

   $ oc new-project service-telemetry

   Copy to Clipboard Toggle word wrap

2. 在命名空间中创建 OperatorGroup，以便您可以调度 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 OperatorGroup。

3. 为 cert-manager Operator 创建命名空间：

   $ oc create -f - <<EOF
   apiVersion: project.openshift.io/v1
   kind: Project
   metadata:
     name: openshift-cert-manager-operator
   spec:
     finalizers:
     - kubernetes
   EOF

   Copy to Clipboard Toggle word wrap

4. 为 cert-manager Operator 创建 OperatorGroup：

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1
   kind: OperatorGroup
   metadata:
     name: openshift-cert-manager-operator
     namespace: openshift-cert-manager-operator
   spec: {}
   EOF

   Copy to Clipboard Toggle word wrap

5. 使用 redhat-operators CatalogSource 订阅 cert-manager Operator：

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

   Copy to Clipboard Toggle word wrap

6. 验证您的 ClusterServiceVersion。确保 cert-manager Operator 显示 Succeeded 阶段：

   $ oc get csv --namespace openshift-cert-manager-operator --selector=operators.coreos.com/openshift-cert-manager-operator.openshift-cert-manager-operator
   
   NAME                            DISPLAY                                       VERSION   REPLACES   PHASE
   openshift-cert-manager.v1.7.1   cert-manager Operator for Red Hat OpenShift   1.7.1-1              Succeeded

   Copy to Clipboard Toggle word wrap

7. 使用 redhat-operators CatalogSource 订阅 AMQ Interconnect Operator：

   $ oc create -f - <<EOF
   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
     name: amq7-interconnect-operator
     namespace: service-telemetry
   spec:
     channel: 1.10.x
     installPlanApproval: Automatic
     name: amq7-interconnect-operator
     source: redhat-operators
     sourceNamespace: openshift-marketplace
   EOF

   Copy to Clipboard Toggle word wrap

8. 验证您的 ClusterServiceVersion。确保 amq7-interconnect-operator.v1.10.x 显示 Succeeded 的阶段：

   $ oc get csv --selector=operators.coreos.com/amq7-interconnect-operator.service-telemetry
   
   NAME                                  DISPLAY                                  VERSION   REPLACES                             PHASE
   amq7-interconnect-operator.v1.10.15   Red Hat Integration - AMQ Interconnect   1.10.15   amq7-interconnect-operator.v1.10.4   Succeeded

9. 要在 Prometheus 中存储指标，您必须使用 community-operators CatalogSource 启用 Prometheus Operator：

   警告

   社区 Operator 是尚未被红帽审查或验证的 Operator。社区 Operator 应谨慎使用，因为其稳定性未知。红帽不支持社区 Operator。

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

   Copy to Clipboard Toggle word wrap

10. 验证 Prometheus Succeeded 的 ClusterServiceVersion：

    $ oc get csv --selector=operators.coreos.com/prometheus.service-telemetry
    
    NAME                        DISPLAY               VERSION   REPLACES                    PHASE
    prometheusoperator.0.56.3   Prometheus Operator   0.56.3    prometheusoperator.0.47.0   Succeeded

11. 要在 Elasticsearch 中存储事件，您必须使用 certified-operators CatalogSource 在 Kubernetes (ECK) Operator 上启用 Elastic Cloud：

    警告

    认证的 Operator 是来自主要独立软件供应商(ISV)的 Operator。红帽与 ISV 合作打包并提供，但不支持经过认证的 Operator。支持由 ISV 提供。
