第 3 章 安装 Service Telemetry Framework 的核心组件

流程

1. 登录到托管 STF 的 Red Hat OpenShift Container Platform 环境。

2. 要在 Prometheus 中存储指标，请使用 redhat-operators CatalogSource 启用 Cluster Observability Operator：

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

3. 验证 Cluster Observability Operator 的 ClusterServiceVersion 的状态是否为 Succeeded ：

   $ oc wait --for jsonpath="{.status.phase}"=Succeeded csv --namespace=openshift-operators -l operators.coreos.com/cluster-observability-operator.openshift-operators
   
   clusterserviceversion.operators.coreos.com/observability-operator.v0.0.26 condition met

流程

1. 登录到托管 STF 的 Red Hat OpenShift Container Platform 环境。

2. 验证 Red Hat OpenShift Container Platform 集群中尚未安装 cert-manager。如果返回任何结果，请不要安装另一个 cert-manager 实例：

   $ oc get sub --all-namespaces -o json | jq '.items[] | select(.metadata.name | match("cert-manager")) | .metadata.name'

3. 为 cert-manager Operator 创建命名空间：

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

4. 为 cert-manager Operator 创建 OperatorGroup：

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

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: cert-manager-operator
     labels:
       operators.coreos.com/openshift-cert-manager-operator.cert-manager-operator: ""
   spec:
     channel: stable-v1
     installPlanApproval: Automatic
     name: openshift-cert-manager-operator
     source: redhat-operators
     sourceNamespace: openshift-marketplace
   EOF

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

   oc wait --for jsonpath="{.status.phase}"=Succeeded csv --namespace=cert-manager-operator --selector=operators.coreos.com/openshift-cert-manager-operator.cert-manager-operator
   
   clusterserviceversion.operators.coreos.com/cert-manager-operator.v1.12.1 condition met

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. 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-1.5
     installPlanApproval: Automatic
     name: service-telemetry-operator
     source: redhat-operators
     sourceNamespace: openshift-marketplace
   EOF

4. 验证 Service Telemetry Operator 和依赖 Operator 的阶段为 Succeeded ：

   $ oc wait --for jsonpath="{.status.phase}"=Succeeded csv --namespace=service-telemetry -l operators.coreos.com/service-telemetry-operator.service-telemetry ; oc get csv --namespace service-telemetry
   
   clusterserviceversion.operators.coreos.com/service-telemetry-operator.v1.5.1700688542 condition met
