第 6 章 将服务 Telemetry Framework 升级到 1.3

流程

1. 检索当前 ServiceTelemetry 对象并记录内容，特别是 clouds 参数，因为在升级 Operator 前必须删除此参数。

   $ oc get stf default -oyaml

2. 修改 ServiceTelemetry 对象，以清除 clouds 参数，并将其设置为空列表。将 cloudRemoveOnMissing 设置为 true 以删除所有智能网关。

   警告

   这个命令会停止所有监控功能，直到升级后，云 对象被重新定义。如果使用默认云配置，则 ServiceTelemetry 对象中没有定义它。

   $ oc patch stf default --patch $'spec:\n  clouds: []\n  cloudsRemoveOnMissing: true' --type=merge

3. 监控智能网关 pod，直到被完全终止和删除：

   $ oc get pods --selector app=smart-gateway --watch
   
   NAME                                                      READY   STATUS    RESTARTS   AGE
   default-cloud1-ceil-meter-smartgateway-58cc854f4-hgk92    1/1     Running   0          2m42s
   default-cloud1-coll-meter-smartgateway-6c76f9786d-crn9b   2/2     Running   0          2m55s
   default-cloud1-coll-meter-smartgateway-6c76f9786d-crn9b   2/2     Terminating   0          3m12s
   default-cloud1-ceil-meter-smartgateway-58cc854f4-hgk92    1/1     Terminating   0          3m
   ...

4. 检索 Smart Gateway Operator 的订阅 名称：

   $ oc get sub smart-gateway-operator-stable-1.2-redhat-operators-openshift-marketplace
   
   NAME                                                                       PACKAGE                  SOURCE             CHANNEL
   smart-gateway-operator-stable-1.2-redhat-operators-openshift-marketplace   smart-gateway-operator   redhat-operators   stable-1.2

5. 删除 Smart Gateway Operator 订阅：

   $ oc delete sub smart-gateway-operator-stable-1.2-redhat-operators-openshift-marketplace
   
   subscription.operators.coreos.com "smart-gateway-operator-stable-1.2-redhat-operators-openshift-marketplace" deleted

6. 检索 Smart Gateway Operator ClusterServiceVersion:

   $ oc get csv -o name | grep -E 'smart-gateway'
   
   clusterserviceversion.operators.coreos.com/smart-gateway-operator.v2.2.1623675667

7. 删除 Smart Gateway Operator ClusterServiceVersion:

   $ oc delete clusterserviceversion.operators.coreos.com/smart-gateway-operator.v2.2.1623675667
   
   clusterserviceversion.operators.coreos.com "smart-gateway-operator.v2.2.1623675667" deleted

8. 删除 SmartGateway 自定义资源定义：

   $ oc delete crd smartgateways.smartgateway.infra.watch
   
   customresourcedefinition.apiextensions.k8s.io "smartgateways.smartgateway.infra.watch" deleted

9. 对 Service Telemetry Operator 订阅进行补丁以使用 stable-1.3 频道：

   $ oc patch sub service-telemetry-operator --patch $'spec:\n  channel: stable-1.3' --type=merge
   
   subscription.operators.coreos.com/service-telemetry-operator patched

10. 监控 oc get csv 命令的输出，直到安装了 Smart Gateway Operator，并且服务 Telemetry Operator 为 Pending for 版本 1.2 和 1.3：

    $ oc get csv
    
    NAME                                         DISPLAY                                         VERSION          REPLACES                                     PHASE
    amq7-cert-manager.v1.0.0                     Red Hat Integration - AMQ Certificate Manager   1.0.0                                                         Succeeded
    amq7-interconnect-operator.v1.2.4            Red Hat Integration - AMQ Interconnect          1.2.4            amq7-interconnect-operator.v1.2.3            Succeeded
    elastic-cloud-eck.v1.6.0                     Elasticsearch (ECK) Operator                    1.6.0            elastic-cloud-eck.v1.5.0                     Succeeded
    prometheusoperator.0.47.0                    Prometheus Operator                             0.47.0           prometheusoperator.0.37.0                    Succeeded
    service-telemetry-operator.v1.2.1623675667   Service Telemetry Operator                      1.2.1623675667                                                Pending
    service-telemetry-operator.v1.3.1622734200   Service Telemetry Operator                      1.3.1622734200   service-telemetry-operator.v1.2.1623675667   Pending
    smart-gateway-operator.v3.0.1622734308       Smart Gateway Operator                          3.0.1622734308                                                Succeeded

11. 删除 Service Telemetry Operator v1.2 ClusterServiceVersion:

    $ oc delete csv service-telemetry-operator.v1.2.1623675667
    
    clusterserviceversion.operators.coreos.com "service-telemetry-operator.v1.2.1623675667" deleted

12. 编辑 ServiceTelemetry 对象并插入您之前记录的 cloud 参数的内容。如果之前没有定义 cloud 参数，因为您使用默认的 Smart Gateway 实例，删除 cloud: [] 参数。

    $ oc edit stf default

13. 验证智能卡是否已恢复：

    $ oc get pods --selector app=smart-gateway
    
    NAME                                                      READY   STATUS    RESTARTS   AGE
    default-cloud1-ceil-meter-smartgateway-6484b98b68-sl7mb   2/2     Running   0          5m56s
    default-cloud1-coll-meter-smartgateway-799f687658-nfzr6   2/2     Running   0          6m6s
