红帽全球峰会3.3. 升级中央集群
在创建了 Central 数据库的备份并使用置备捆绑包生成必要的资源后，下一步是升级 Central 集群。这个过程涉及升级 Central 和 Scanner。
3.3.1. 升级 Central
您可以通过下载和部署更新的镜像，将 Central 更新到最新版本。
如果使用 Kubernetes，请输入 kubectl 而不是 oc。
流程
要更新 Central 镜像，请运行以下命令：
$ oc -n stackrox set image deploy/central \ central=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:4.7.8要更新 Central-db 镜像，请运行以下命令：
$ oc -n stackrox set image deploy/central-db \ central-db=registry.redhat.io/advanced-cluster-security/rhacs-central-db-rhel8:4.7.8 \ init-db=registry.redhat.io/advanced-cluster-security/rhacs-central-db-rhel8:4.7.8要更新配置控制器镜像，请运行以下命令：
$ oc -n stackrox set image deploy/config-controller \ manager=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:4.7.8
验证
验证新 pod 是否已部署：
$ oc get deploy -n stackrox -o wide$ oc get pod -n stackrox --watch
3.3.2. 升级扫描器
您可以通过下载和部署更新的镜像将 Scanner 更新至最新版本。
如果使用 Kubernetes，请输入 kubectl 命令而不是 oc 命令。
流程
如果已创建了自定义 Scanner 配置，则必须在更新 Scanner 配置文件前应用这些更改：
要生成扫描器，请运行以下命令：
$ roxctl -e "$ROX_CENTRAL_ADDRESS" scanner generate要应用 TLS secret YAML 文件，请运行以下命令：
$ oc apply -f scanner-bundle/scanner/02-scanner-03-tls-secret.yaml要应用 Scanner 配置 YAML 文件，请运行以下命令：
$ oc apply -f scanner-bundle/scanner/02-scanner-04-scanner-config.yaml
要更新 Scanner 镜像，请运行以下命令：
$ oc -n stackrox set image deploy/scanner \ scanner=registry.redhat.io/advanced-cluster-security/rhacs-scanner-rhel8:4.7.8要更新 Scanner 数据库镜像，请运行以下命令：
$ oc -n stackrox set image deploy/scanner-db \ db=registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:4.7.8 \ init-db=registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:4.7.8
验证
要验证新 pod 是否已部署，请运行以下命令：
$ oc get deploy -n stackrox -o wide$ oc get pod -n stackrox --watch
3.3.3. 验证 Central 集群升级
在升级了 Central 和 Scanner 后，验证该中央集群升级已完成。
如果使用 Kubernetes，请输入 kubectl 而不是 oc。
流程
运行以下命令检查 Central 日志：
$ oc logs -n stackrox deploy/central -c central输出示例
