5.6. 在单一命名空间中安装 Red Hat Quay Operator 时启用监控

步骤

1. 输入以下命令检查 cluster-monitoring-config ConfigMap 对象是否存在：

   $ oc -n openshift-monitoring get configmap cluster-monitoring-config

   Copy to Clipboard Toggle word wrap

   输出示例

   Error from server (NotFound): configmaps "cluster-monitoring-config" not found

   Copy to Clipboard Toggle word wrap

2. 可选：如果 ConfigMap 对象不存在，请创建一个 YAML 清单。在以下示例中，该文件名为 cluster-monitoring-config.yaml。

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: cluster-monitoring-config
     namespace: openshift-monitoring
   data:
     config.yaml: |

   Copy to Clipboard Toggle word wrap

3. 可选：如果 ConfigMap 对象不存在，请创建 ConfigMap 对象：

   $ oc apply -f cluster-monitoring-config.yaml

   Copy to Clipboard Toggle word wrap

   输出示例

   configmap/cluster-monitoring-config created

   Copy to Clipboard Toggle word wrap

4. 运行以下命令，确保 ConfigMap 对象存在：

   $ oc -n openshift-monitoring get configmap cluster-monitoring-config

   Copy to Clipboard Toggle word wrap

   输出示例

   NAME                        DATA   AGE
   cluster-monitoring-config   1      12s

   Copy to Clipboard Toggle word wrap

步骤

1. 输入以下命令检查 user-workload-monitoring-config ConfigMap 对象是否存在：

   $ oc -n openshift-user-workload-monitoring get configmap user-workload-monitoring-config

   Copy to Clipboard Toggle word wrap

   输出示例

   Error from server (NotFound): configmaps "user-workload-monitoring-config" not found

   Copy to Clipboard Toggle word wrap

2. 如果 ConfigMap 对象不存在，请创建一个 YAML 清单。在以下示例中，该文件名为 user-workload-monitoring-config.yaml。

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: user-workload-monitoring-config
     namespace: openshift-user-workload-monitoring
   data:
     config.yaml: |

   Copy to Clipboard Toggle word wrap

3. 可选：输入以下命令来创建 ConfigMap 对象：

   $ oc apply -f user-workload-monitoring-config.yaml

   Copy to Clipboard Toggle word wrap

   输出示例

   configmap/user-workload-monitoring-config created

   Copy to Clipboard Toggle word wrap

步骤

1. 输入以下命令检查监控用户定义的项目是否正在运行：

   $ oc get pods -n openshift-user-workload-monitoring

   Copy to Clipboard Toggle word wrap

   输出示例

   No resources found in openshift-user-workload-monitoring namespace.

   Copy to Clipboard Toggle word wrap

2. 输入以下命令编辑 cluster-monitoring-config ConfigMap ：

   $ oc -n openshift-monitoring edit configmap cluster-monitoring-config

   Copy to Clipboard Toggle word wrap

3. 在 config.yaml 文件中设置 enableUserWorkload: true，以便在集群中为用户定义的项目启用监控：

   apiVersion: v1
   data:
     config.yaml: |
       enableUserWorkload: true
   kind: ConfigMap
   metadata:
     annotations:

   Copy to Clipboard Toggle word wrap

4. 输入以下命令保存文件，应用更改并确保适当的 pod 正在运行：

   $ oc get pods -n openshift-user-workload-monitoring

   Copy to Clipboard Toggle word wrap

   输出示例

   NAME                                   READY   STATUS    RESTARTS   AGE
   prometheus-operator-6f96b4b8f8-gq6rl   2/2     Running   0          15s
   prometheus-user-workload-0             5/5     Running   1          12s
   prometheus-user-workload-1             5/5     Running   1          12s
   thanos-ruler-user-workload-0           3/3     Running   0          8s
   thanos-ruler-user-workload-1           3/3     Running   0          8s

   Copy to Clipboard Toggle word wrap

步骤

1. 为 Service 对象创建 YAML 文件：

   $ cat <<EOF >  quay-service.yaml
   
   apiVersion: v1
   kind: Service
   metadata:
     annotations:
     labels:
       quay-component: monitoring
       quay-operator/quayregistry: example-registry
     name: example-registry-quay-metrics
     namespace: quay-enterprise
   spec:
     ports:
     - name: quay-metrics
       port: 9091
       protocol: TCP
       targetPort: 9091
     selector:
       quay-component: quay-app
       quay-operator/quayregistry: example-registry
     type: ClusterIP
   EOF

   Copy to Clipboard Toggle word wrap

2. 运行以下命令来创建 Service 对象：

   $  oc apply -f quay-service.yaml

   Copy to Clipboard Toggle word wrap

   输出示例

   service/example-registry-quay-metrics created

   Copy to Clipboard Toggle word wrap

步骤

1. 为 ServiceMonitor 资源创建 YAML 文件：

   $ cat <<EOF >  quay-service-monitor.yaml
   
   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
     labels:
       quay-operator/quayregistry: example-registry
     name: example-registry-quay-metrics-monitor

     - port: quay-metrics
     namespaceSelector:
       any: true
     selector:
       matchLabels:
         quay-component: monitoring
   EOF
